Lignin polymer is biologically and chemically stable and requires highly vigorous conditions for de-polymerization, and subsequent stabilization of the monomeric conversion products to prevent re-polymerization and char production. The Lignin-to-Liquid (LtL) process is a solvolytic conversion of lignin with formic acid. Formic acid has been shown to both catalyze the de-polymerization and supply hydrogen that stabilizes the de-polymerization products. In this paper, lignin from Eucalyptus wood was used as the feedstock, and the LtL-process was performed in both aqueous and ethanolic solvent systems. The experimental variables were different levels of loading in the reactor, stirred and non-stirred conditions, and different reaction temperatures. The bio-oil consisted mostly of phenolic compounds, and the bio-oil yields differed with type of the solvent used, level of loading in the reactor, stirring condition, and operating temperature. More than 55 wt.% of the lignin was recovered as bio-oil at 320 °C at stirred conditions when the reactor was loaded at high level. Overall, the ethanolic solvent together with maximum level of loading in the reactor under stirred condition resulted in the highest bio-oil yield. Elemental balance data for bio-oil and char yields and the molecular composition of the bio-oils were also investigated using, respectively, elemental analysis and GC-MS. Finally, principal component analysis was used as well to systematically explore the relationship between the bio-oil and char yields and the reaction conditions.
木质素聚合物在生物和化学上是稳定的,需要高度剧烈的条件进行脱聚合,并随后稳定单体转化产物,以防止再聚合和炭的产生。木质素转化为液体(LtL)工艺是木质素与甲酸的溶剂化转化。甲酸已被证明既能催化脱聚合,又能提供稳定脱聚合产物的氢气。本文以桉树木质素为原料,在水溶剂和乙醇溶剂体系中进行了LtL工艺。实验变量是反应器中不同的负载水平、搅拌和非搅拌条件以及不同的反应温度。生物油主要由酚类化合物组成,生物油的产率因所用溶剂的类型、反应器中的负载水平、搅拌条件和操作温度而异。当反应器在高水平下加载时,在320°C的搅拌条件下,超过55wt.%的木质素以生物油的形式回收。总的来说,在搅拌条件下,乙醇溶剂与反应器中的最大负载水平一起导致最高的生物油产率。还分别使用元素分析和GC-MS研究了生物油和焦炭产量的元素平衡数据以及生物油的分子组成。最后,利用主成分分析法系统地探讨了生物油和焦炭产率与反应条件之间的关系。

The long term use of pure vegetable oil in diesel engines should be thoroughly evaluated from different perspectives including engine performance, deposit formation, etc. to ensure its compatibility. In line with that, the trilateral correlation of spray characteristics, combustion parameters, and deposit formation in the injector hole of a high-speed, 4-stroke, direct injection diesel engine fueled with pure Jatropha oil and diesel fuel (DF) was studied. Jatropha oil was investogated at room temperature 30 oC (PSJO30) and in preheated form at 90 oC (PSJO90). The expertimental tests were conducted in two phases: (i)- investigation of the spray characteristics of the fuels including cone angle and penetration length at 200 bar of injection pressure, (ii)- investigation of the combustion characteristics (i.e., thermal efficiency and engine emissions) and deposits formation in the injector hole of the diesel engine at 0 h and 300 h of operation. The results obtained showed large differences between the spray characteristics of PJO30 and the other fuels investigated. Moreover, this fuel led to significant reductions in NOx emissions (14.69-20.30%) and thermal efficiency (3.04-4.41%) but large increases in CO emissions (26.36-77.57%),  HC emissions (48.98-77.85%), and smoke (58.43-131.71%). It also resulted in huge deposits formed in the injector hole after 300 h of the endurance test compared to DF and PJO90 as revealed by optical observations using scanning electron microscopy analysis. Overall and compared to DF, PSJO30 cannot be recommemded for long term use in diesel engines while PSJO90 may only be considered as an alternative fuel in the short term.
对柴油发动机长期使用纯植物油应从发动机性能、沉积物形成等不同角度进行全面评估,以确保其兼容性。在此基础上,研究了以纯麻疯树油和柴油(DF)为燃料的高速四冲程直喷柴油机喷油器孔内喷雾特性、燃烧参数和沉积形成的三边相关性。在室温30℃(PSJO30)和预热90℃(PSJO90)下研究麻疯树油。实验测试分两个阶段进行:(i)-在200巴喷射压力下研究燃料的喷射特性,包括锥角和穿透长度;(ii)-研究柴油发动机在运行0和300小时时的燃烧特性(即热效率和发动机排放)和喷油器孔中的沉积物形成情况。实验结果表明,PJO30的喷雾特性与其他燃油存在较大差异。此外,该燃料显著降低了NOx排放量(14.69-20.30%)和热效率(3.04-4.41%),但大幅增加了CO排放量(26.36-77.57%)、HC排放量(48.98-77.85%)和烟雾(58.43-131.71%)。与DF和PJO90相比,使用扫描电子显微镜分析的光学观察结果显示,在300小时的耐久性测试后,在注入孔中形成了巨大的沉积物。总的来说,与DF相比,PSJO30不能被推荐长期用于柴油发动机,而PSJO90只能在短期内被视为替代燃料。

In-situ catalytic pyrolysis of biomass has been extensively studied in recent years for cost-competitive production of high quality bio-oil. To achieve that, numerous catalysts have been studied to facilitate in-situ upgrading of low-grade condensable vapors (bio-oil) by converting oxygenated compounds and large-molecule species. In this review, these catalysts are categorized in different families and a systematic evaluation of the catalyst effects on pyrolysis products and their characteristics is carried out with respect to the scale of the experimental setup. Among these catalysts, microporous zeolites are considered as most promising in terms of performance and the potential to tailor the desired bio-oil properties. More specifically, the prominent advantages of zeolites include efficient deoxygenation and molecular weight reduction of the resultant bio-oil, while the main drawbacks are decreases in the yield of bio-oil’s organic phase and catalyst deactivation by coke deposition. In addition to the zeolite-based catalysts, other catalysts including mesoporous aluminosilicates, a widely-applied class of catalysts used for deoxygenation of bio-oil as well as alkaline compounds are also reviewed and discussed herein. The research on the latter has not been extensive but the preliminary results have revealed their potential for deoxygenation of bio-oil, production of hydrocarbons, and reduction of undesired compounds. Nevertheless, these catalysts need to be further investigated systematically. Overall, further development of dedicated catalysts for selective deoxygenation and cracking of bio-oil would be essential for scaling up the existing pyrolysis technologies to achieve commercial production of biofuels through pyrolysis.
近年来,生物质原位催化热解技术得到了广泛的研究,以获得具有成本竞争力的高品质生物油。为了实现这一目标,人们研究了许多催化剂,通过转化含氧化合物和大分子物质来促进低品位可冷凝蒸汽(生物油)的原位升级。本文对这些催化剂进行了分类,并结合实验装置的规模,系统评价了催化剂对热解产物的影响及其特性。在这些催化剂中,微孔沸石被认为是最有前途的催化剂,具有定制所需生物油性质的潜力。更具体地说,沸石的突出优点是高效脱氧和降低所得生物油的分子量,而主要缺点是生物油的有机相收率降低和焦炭沉积导致催化剂失活。除沸石基催化剂外,还对介孔硅铝酸盐等催化剂进行了综述和讨论。介孔硅铝酸盐是一类广泛应用于生物油和碱性化合物脱氧的催化剂。对后者的研究还不是很广泛,但初步结果已经揭示了它们在生物油脱氧、碳氢化合物生产和减少不需要的化合物方面的潜力。然而,这些催化剂需要进一步系统地研究。总的来说,进一步开发用于生物油选择性脱氧和裂解的专用催化剂对于扩大现有热解技术的规模,通过热解实现生物燃料的商业化生产至关重要。

An experimental study was carried out on a large stationary compression ignition engine to evaluate the long-term compatibility and durability issues associated with the use of crude palm oil as fuel. Two different preheating temperatures (60 and 80 °C) were adopted to assess the potential improvements related to lower fuel viscosity. The results obtained, in terms of in-cylinder carbon deposits and engine wear, were compared with the results obtained using ordinary diesel fuel. For each fuel and preheating temperature, the engine was operated for 300 consecutive h, during which several engine lubricant samples were collected and analysed to determine soot and fuel contaminations, viscosity alterations, and the presence of different wear-related metals (measured by atomic absorption spectroscopy). At the end of each 300 h endurance test, the carbon deposits were scraped from engine cylinders and examined through thermogravimetric analysis (TGA). It was found that the use of crude palm oil caused a remarkable increment of in-cylinder deposits formation compared with ordinary diesel. The lubricant analysis also revealed a faster viscosity degradation and consequent stronger engine wear, above all with the lower preheating temperature. The results obtained confirmed that continuous engine operation (i.e., without a complete lubricant change) should be carefully reduced when fuelling with crude palm oil. Moreover, the findings obtained herein confirmed the favourable impacts of fuel preheating at 80 °C compared to 60 °C, i.e., reduced carbon deposits by 27% and extended engine operation time by 30%.
在大型固定式压缩点火发动机上进行了一项实验研究,以评估使用粗棕榈油作为燃料的长期兼容性和耐久性问题。采用两种不同的预热温度(60°C和80°C)来评估与降低燃料粘度相关的潜在改进。在缸内积碳和发动机磨损方面,与使用普通柴油得到的结果进行了比较。对于每种燃料和预热温度,发动机连续运行300小时,在此期间收集和分析几种发动机润滑油样品,以确定烟灰和燃料污染,粘度变化以及不同磨损相关金属的存在(通过原子吸收光谱测量)。在每次300小时耐力测试结束时,从发动机气缸中刮取碳沉积,并通过热重分析(TGA)进行检测。研究发现,与普通柴油相比,使用粗棕榈油导致缸内沉积物形成显著增加。对润滑油的分析还显示,粘度下降更快,因此发动机磨损更严重,尤其是预热温度较低。所获得的结果证实,在使用粗棕榈油加油时,应小心减少发动机的连续运行(即没有完全更换润滑油)。此外,本文的研究结果证实,与60°C相比,80°C燃料预热的有利影响,即减少了27%的碳沉积,延长了30%的发动机运行时间。

Here we report on a static, algebraic, spreadsheet-implemented modeling approach to estimate the costs, energy inputs and outputs, and global warming potential of biomass feedstocks. Inputs to the model included literature sourced data for: environmental factors, crop physiological-parameters such as radiation use efficiency and water use efficiency, and crop cost components. Using an energy-input-output life-cycle-assessment approach, we calculated the energy associated with each cost component, allowing an estimate of the total energy required to produce the crop and fuel alongside the energy return on investment. We did this for crop scenarios in the upper Midwest US and Far West US (for algae). Our results suggested that algae are capable of the highest areal biomass production rates of 120 MG/(ha·a), ten times greater than Maize. Algal fuel systems had the highest costs, ranging from 28 to 65 US $/GJ, compared to 17 US $/GJ for Maize ethanol. Algal fuel systems had the lowest energy returns on investment, nearly 0, compared to 25 for Switchgrass to ethanol. The carbon equivalent emissions associated with the production schemes predictions ranged from 40 (Maize) to 180 (algae PBR) CO2eq/GJnet. The promise of low cost fuel and carbon neutrality from algae is demonstrated here to be extremely challenging for fundamental reasons related to the capital-intensive nature of the cultivation system.
在这里,我们报告了一种静态的、代数的、电子表格实现的建模方法,以估计生物质原料的成本、能源投入和产出以及全球变暖的潜力。该模型的输入包括文献来源的数据:环境因素、作物生理参数,如辐射利用效率和水分利用效率,以及作物成本组成部分。使用能源投入-产出生命周期评估方法,我们计算了与每个成本组成部分相关的能源,从而可以估计生产作物和燃料所需的总能源以及能源投资回报。我们这样做是针对美国中西部上游和美国西部偏远地区的作物情况(针对藻类)。我们的研究结果表明,藻类的面积生物量生产率最高,为120 MG/(ha·a),是玉米的十倍。藻类燃料系统的成本最高,从28至65美元/吉焦不等,而玉米乙醇的成本为17美元/吉吉焦。藻类燃料系统的能源投资回报率最低,接近0,相比之下,Switchgrass生产乙醇的能源回报率为25。与生产计划预测相关的碳当量排放量从40(玉米)到180(藻类PBR)CO2eq/GJnet不等。低成本燃料和藻类碳中和的前景在这里被证明是极具挑战性的,这是由于与种植系统的资本密集性有关的基本原因。

Novel synthesis of Lewis and Bronsted acid sites incorporated CS-Fe3O4@SO3H catalyst and its application in one-pot synthesis of tri(furyl)methane under aqueous media 引入CS-Fe3O4@SO3H催化剂的Lewis和Bronsted酸位合成新方法及其在水介质中一锅合成三(糠基)甲烷中的应用

A sustainable chitosan (CS)-derived magnetic solid acid catalyst (CS-Fe3O4@SO3H) incorporated by Lewis and Bronsted acid sites was synthesized in an eco-friendly manner through the preloading of iron on CS and one-pot low-temperature carbonization/sulfonation. The carbonization/sulfonation of CS-Fe3O4 using p-Toluenesulfonic acid (p-TSA) at 140 oC resulted in the loss of ammonia in some extent and provided bifunctional sites on the catalyst. This heterogeneous catalyst was found to be highly selective for the conversion of xylose and arabinose to furfural (FF) and subsequent tri(furyl)methane (TFM) formation by the condensation with furan in the same reaction vessel without any purification. The outcome of optimization under different reaction parameters showed that only 20 wt.% of CS-Fe3O4@SO3H catalyst resulted in 81% TFM yield from xylose while arabinose gave a 70% TFM yield in dimethyl sulfoxide (DMSO):water with high selectivity. This green protocol provides an easy isolation of products and minimizes the formation of polymerized by-products. The catalyst can be readily recovered and efficiently reused for three consecutive catalytic cycles without any significant loss on product yields.
一种可持续的壳聚糖磁性固体酸催化剂(CS-Fe3O4@SO3H)通过在CS上预加载铁和一锅低温碳化/磺化,以环保的方式合成了由Lewis和Bronsted酸位点结合的铁。使用对甲苯磺酸(p-TSA)在140℃下对CS-Fe3O4进行碳化/磺化,在一定程度上导致了氨的损失,并在催化剂上提供了双功能位点。发现这种多相催化剂对木糖和阿拉伯糖转化为糠醛(FF)以及随后通过在同一反应容器中与呋喃缩合而不进行任何纯化而形成三(呋喃)甲烷(TFM)具有高度选择性。在不同反应参数下的优化结果表明CS-Fe3O4@SO3H催化剂从木糖中得到81%的TFM产率,而阿拉伯糖在二甲基亚砜(DMSO):水中以高选择性得到70%的TFM收率。这种绿色方案提供了产品的简单分离,并最大限度地减少了聚合副产物的形成。催化剂可以容易地回收并有效地重复使用三个连续的催化循环,而不会对产物产率造成任何显著损失。

Biodiesel has huge potentials as a green and technologically feasible alternative to fossil diesel. However, biodiesel production from edible oil crops has been widely criticized while nonedible oil plants are associated with some serious disadvantages, such as high cost, low oil yield, and unsuitable oil composition. The next generation sequencing (NGS), omics technologies, and genetic engineering have opened new paths toward achieving high performance-oil plants varieties for commercial biodiesel production. The intent of the present review paper is to review and critically discuss the recent genetic and metabolic engineering strategies developed to overcome the shortcoming faced in nonedible plants, including Jatropha curcas and Camelina sativa, as emerging platforms for biodiesel production. These strategies have been looked into three different categories. Through the first strategy aimed at enhancing oil content, the key genes involved in triacylglycerols (TAGs) biosynthesis pathway (e.g., diacylglycerol acyltransferase (DGAT), acetyl-CoA carboxylase (ACCase), and glycerol‐3‐phosphate dehydrogenase (GPD1)), genes affecting seed size and plant growth (e.g., transcription factors (WRI1), auxin response factor 19 (ARF19),  leafy cotyledon1 (LEC1), purple acid phosphatase 2 (PAP2), G-protein c subunit 3 (AGG3), and flowering locus T (FT)), as well as genes involved in TAGs degradation (e.g., sugar-dependent protein 1 triacylglycerol lipase (SDP1)) have been deliberated. While through the second strategy targeting enhanced oil composition, suppression of the genes involved in the biosynthesis of linoleic acids (e.g., fatty acid desaturase (FAD2), fatty acid elongase (FAE1), acyl-ACP thioesterase (FATB), and ketoacyl-ACP synthase II (KASII)), suppression of the genes encoding toxic metabolites (curcin precursor and casbene synthase (JcCASA)), and finally, engineering the genes responsible for the production of unusual TAGs (e.g., Acetyl-TAGs and hydroxylated fatty acids (HFA)) have been debated. In addition to those, enhancing tolerance to biotic (pest and disease) and abiotic (drought, salinity, freezing, and heavy metals) stresses as another important genetic engineering strategy to facilitate the cultivation of nonedible oil plants under conditions unsuitable for food crops has been addressed. Finally, the challenges faced prior to successful commercialization of the resultant GM oil plants such have been presented.
生物柴油作为一种绿色且技术可行的化石柴油替代品,具有巨大的潜力。然而,食用油料作物生产生物柴油受到了广泛的批评,而非食用油料作物生产生物柴油存在成本高、出油率低、油成分不合适等严重缺点。下一代测序(NGS)、组学技术和基因工程为实现用于商业生物柴油生产的高性能油料植物品种开辟了新的途径。本综述的目的是回顾和批判性地讨论最近开发的遗传和代谢工程策略,以克服非食用植物面临的缺点,包括麻疯树和亚麻荠,作为生物柴油生产的新兴平台。这些策略被分为三个不同的类别。通过提高含油量的第一个策略,涉及三酰基甘油(TAGs)生物合成途径的关键基因(如二酰基甘油酰基转移酶(DGAT)、乙酰辅酶a羧化酶(ACCase)和甘油- 3 -磷酸脱氢酶(GPD1)),影响种子大小和植物生长的基因(如转录因子(WRI1)、生长素反应因子19 (ARF19)、叶子叶1 (LEC1)、紫色酸性磷酸酶2 (PAP2)、g -蛋白c亚基3 (AGG3)和开花位点T (FT)),以及参与标签降解的基因(例如,糖依赖性蛋白1三酰基甘油脂肪酶(SDP1))已被审议。而通过第二种策略,针对增强的油成分,抑制参与亚油酸生物合成的基因(如脂肪酸去饱和酶(FAD2)、脂肪酸延长酶(FAE1)、酰基- acp硫酯酶(FATB)和酮酰基- acp合成酶II (KASII)),抑制编码有毒代谢物的基因(curcin前体和casbene合成酶(JcCASA)),最后,设计负责产生异常标签的基因(如:乙酰基标签和羟基化脂肪酸(HFA)一直存在争议。除此之外,提高对生物(病虫害)和非生物(干旱、盐碱、冰冻和重金属)胁迫的耐受性是另一个重要的基因工程策略,以促进在不适合粮食作物的条件下种植非食用油类植物。最后,所面临的挑战,在成功的商业化所产生的转基因油料工厂已经提出。

Biological pretreatment of lignocellulosic biomass is considered to be energy-efficient and cost-effective. In the present study, sorghum husk was biologically pretreated with a white-rot fungus Phanerochaete chrysosporium (MTCC 4955) under submerged static condition. Ligninolytic enzymes like lignin peroxidase (0.843 U/mL) and manganese peroxidase (0.389 U/mL) played an important role in the biological pretreatment of sorghum husk. Activities of different hydrolytic enzymes such as endoglucanase (57.25 U/mL), exoglucanase (4.76 U/mL), filter paperase (0.580 U/mL), glucoamylase (153.38 U/mL), and xylanase (88.14 U/mL) during biological pretreatment of sorghum husk by P. chrysosporium were evaluated. Enzymatic hydrolysis of untreated sorghum husk and biologically pretreated sorghum husk produced 20.07 and 103.0 mg/g reducing sugars, respectively. This result showed a significant increase in reducing sugar production in the biologically pretreated sorghum husk as compared to its untreated counterpart. Biologically pretreated sorghum husk hydrolysate was further fermented for 48 h using Saccharomyces cerevisiae (KCTC 7296), Pachysolen tannophilus (MTCC 1077), and their co-culture resulting in ethanol yields of 2.113, 1.095, and 2.348%, respectively. The surface characteristics of the substrate were evaluated after the delignification and hydrolysis, using FTIR, XRD, and SEM, confirming the effectiveness of the biological pretreatment process.
木质纤维素生物质的生物预处理被认为是节能和经济的。本研究用白腐真菌黄孢原毛平革菌(MTCC 4955)在浸没静态条件下对高粱壳进行生物预处理。木质素过氧化物酶(0.843U/mL)和锰过氧化物酶(0.389U/mL)等木质素水解酶在高粱壳的生物预处理中起着重要作用。对黄孢菌对高粱壳进行生物预处理时,内葡聚糖酶(57.25U/mL)、外葡聚糖酶(4.76U/mL),滤纸酶(0.580U/mL)和葡糖淀粉酶(153.38U/mL)以及木聚糖酶(88.14U/mL)等不同水解酶的活性进行了评价。未处理高粱壳和生物预处理高粱壳的酶水解分别产生20.07和103.0mg/g的还原糖。这一结果表明,与未处理的高粱壳相比,生物预处理的高粱皮中的还原糖产量显著增加。使用酿酒酵母(KCTC 7296)、嗜单宁Pachysolen(MTCC 1077)和它们的共培养物进一步发酵生物预处理的高粱壳水解物48小时,乙醇产量分别为2.113、1.095和2.348%。使用FTIR、XRD和SEM对脱木素和水解后的基质表面特性进行了评估,证实了生物预处理工艺的有效性。
