The production of large quantities of bio mass of aquatic floating species especially waterweeds, during the aquatic phase of the flood-pulse characteristics for this ecosystem. Such bio mass could be wisely managed for the production of bio fuels. The aquatic biomass exploitation would require low fossil energy and material inputs leaving a positive energy balance, white minimal interference in the environment. And it is relatively less flammable as compared fossil diesel. It is significantly reduced level of particulate matter emission and also less harmful carbon emission. Currently biodiesel is becoming popular as an environmental friendly fuel. It has been used as in the automotive industry. A major source of energy for our society is the burning of fossil fuels such as coal, petroleum and natural gas. But these sources are found out to be in the limited amounts of available, so those are depleting resources. Bio fuel is much better lubricant than petro diesel and extends engine life. An attempt was made to produce biodiesel from water weeds and discuss technical, socio-economic, and environmental benefits of small scale biofuels such as improving energy access, generation and mitigating environmental pollution at both local and global levels. The obtained result indicated that waterweeds sample should variable sugar content (for 30% of H2SO4 sample) is 1% to 1.2% and Alcohol content should found 2% to 2.4% from 1.5 kg of waterweeds sample. Thus the study has demonstrated systematic approach to disposal of water weeds in solid waste management system. Biodiesel and bio-ethanol production is an alternative approach to fossil fuel.
大量水生漂浮物种特别是水草的生物量的产生,在水相期间具有这种生态系统的洪水脉动特征。这样的生物质量可以被明智地管理,用于生产生物燃料。水生生物质的开发需要较少的化石能源和物质投入,从而保持正能量平衡,对环境的干扰最小。与化石柴油相比,它的可燃性相对较低。它大大降低了颗粒物排放水平,也减少了有害碳排放。目前,生物柴油作为一种环境友好型燃料越来越受欢迎。它已被用于汽车工业。我们社会的主要能源来源是燃烧化石燃料,如煤、石油和天然气。但是这些资源是有限的,所以它们正在消耗资源。生物燃料是比汽油柴油更好的润滑剂,可以延长发动机的寿命。我们尝试从水草中生产生物柴油,并讨论了小规模生物燃料的技术、社会经济和环境效益,如改善能源获取、发电和减轻地方和全球层面的环境污染。结果表明,水草样品的含糖量应为1% ~ 1.2%(含h2so30 %),酒精含量为2% ~ 2.4%(含1.5 kg)。因此,该研究为固体废物管理系统中水草的处理提供了系统方法。生物柴油和生物乙醇生产是化石燃料的一种替代方法。

The Algerian gas condensate may be valuated as a raw matter to obtain maximum ethylene and propylene yields, the latter are used as first materials to produce polyethylene and polypropylene. It is judged utile to substitute ethane as pyrolysis feedstock by the Algerian condensate compounded with ethane. Several dilutions (5%, 10% and 20%) of the gas condensate and its fractions with ethane have been prepared to be used as pyrolysis feedstock. The effect of temperature, residence-time and steam flow on the yield of pyrolysis products have been studied well as their influence on the composition of pyro gas and liquid pyrolysis.

Lignocellulosic biofuel production mainly carried out by two ways: simultaneous saccharification and fermentation (SSF) and separate hydrolysis and fermentation (SHF). In the present study, simultaneous saccharification and fermentation (SSF) was carried out using microwave assisted thermochemically pretreated (0.5 M NaOH for 20 minutes at 120°C in preheated oven) corn husk. Using co-cultures of Saccharomyces cerevisiae and Fusarium oxysporum, SSF process was optimized. Maximum ethanol production (6.24%, v/v) was observed after 24 h of incubation. Further for enhanced ethanol production, effect of different surfactant was carried out on SSF using co-culture strategy. It was found that addition of Tween 60 enhanced the ethanol production upto 6.38% (v/v). Further for addition enhancement of ethanol production, different co-culture strategy was adopted. It was found that maximum ethanol production (6.58% v/v) was obtained when ethanol fermentation was carried out by Fusarium oxysporum followed by Saccharomyces cerevisiae.

Optimization of Composite Layering Effect Based on Measured FormationFracture Height to Length Ratios 基于实测地层裂缝高长比的复合层理效果优化

This study achieves two main goals. First, it develops a method that uses the Composite Layering Effect (CLE) Equation to predict the behavior of potential fractures in conventional and unconventional reservoirs from core samples. The second goal of this study is to determine how different mineralogical and elemental components affect the behavior of fractures predicted using the CLE equation. After the samples are fractured, X-ray Powder Diffraction (XRD) and X-ray Fluorescence (XRF) techniques are executed to measure the mineralogical and elemental compositions of the core samples respectively. In this method, core samples are first obtained from the formation. Next, X-Ray Computed Tomography (CT) is used to determine if core samples have preexisting fractures. The samples are then fractured slightly using Uniaxial Compressive Strength (UCS), in which a compressive-strength machine initiates fractures by applying uniaxial load and stopping automatically upon reaching a predetermined load. CT then confirms the existence of the new fractures, and Image J interprets the height–length ratio of each fracture. These results are used in calculating the CLE. The results of these experiments revealed the relationship between the mineral and elemental compositions of the rocks and the crack dimensions. It was seen that the presence of quartz and clay minerals had the strongest influence on the CLE value due to the brittle behavior of the quartz and ductile behavior of the clay minerals (nacrite). The highest CLE value was recorded for the shale sample that had a preexisting fracture. The fracture patterns developed in the shale samples were mainly parallel to one another. In contrast, the fracture patterns developed in sandstones started out parallel and later merged together to form a connected fracture network.
这项研究实现了两个主要目标。首先,开发了一种利用复合分层效应(CLE)方程从岩心样品中预测常规和非常规储层潜在裂缝行为的方法。本研究的第二个目标是确定不同的矿物学和元素成分如何影响使用CLE方程预测的裂缝行为。试样破碎后,采用x射线粉末衍射(XRD)和x射线荧光(XRF)技术分别测定岩心样品的矿物学和元素组成。在这种方法中,首先从地层中获得岩心样品。接下来,使用x射线计算机断层扫描(CT)来确定岩心样品是否存在先前存在的裂缝。然后使用单轴抗压强度(UCS)稍微破坏样品,其中压缩强度机器通过施加单轴载荷并在达到预定载荷时自动停止来启动断裂。CT确认了新裂缝的存在,图像J解释了每条裂缝的高长比。这些结果用于计算CLE。这些实验结果揭示了岩石的矿物和元素组成与裂缝尺寸之间的关系。可见,石英和粘土矿物的存在对CLE值的影响最大,这是由于石英的脆性和粘土矿物(橄榄石)的延展性。对于已经存在裂缝的页岩样品,记录了最高的CLE值。页岩样品中发育的裂缝模式主要是平行的。相反,砂岩中发育的裂缝模式一开始是平行的,后来合并在一起,形成了一个连接的裂缝网络。

The main objective of this research is to estimate and discuss the effect of shear stress on wax deposition in the hydrocarbon pipeline. Two sets of experimental data were used to analyse the effect of shear stress on wax deposition with and without spiral flow at different inlet coolant temperatures and different flow rates. A new mathematical model was developed during this study to estimate the shear stress, because of the spiral flow, on wax deposition. The concept of this model was based on the forces that influence on the crude oil flow in the pipe, with and without inserting the twisted plate to create spiral flow, depending on the pressure drop along the pipe. The results are presented that, increasing the shear stress, because of the effect of the spiral flow, leads to decrease the wax deposit thickness with increasing the pressure drop while the shear stress decreased in the case of crude oil flow without spiral flow leading to increasing the wax deposit thickness. On the other hand, increasing the inlet coolant temperature leads to decrease the shear stress and wax thickness because of decreasing the value of the crude oil viscosity. This developed model can be considered as a base model for similar studies to calculate the shear stress in the fluid flow pipelines using the twisted plate to create spiral flow.
本研究的主要目的是估计和讨论剪切应力对油气管道中蜡沉积的影响。采用两组实验数据,分析了在不同进口冷却液温度和不同流量下,剪切应力对有和无螺旋流动的蜡沉积的影响。本文建立了一个新的数学模型来估计螺旋流对蜡沉积的剪切应力。该模型的概念是基于影响管道中原油流动的力,根据管道上的压降,是否插入扭曲板以产生螺旋流。结果表明:随着压降的增大,由于螺旋流的影响,增大剪切应力会导致蜡层厚度减小;而原油无螺旋流时,剪切应力减小导致蜡层厚度增大。另一方面,由于原油粘度值的降低,进口冷却液温度的升高导致剪切应力和蜡层厚度的减小。该模型可作为利用扭板产生螺旋流的流体流动管道中剪切应力计算的基础模型。

The field experiment was carried out at the National Horticultural Research Institute (NIHORT) Idi-Ishin Jericho, Ibadan to determine the growth and herbage yield of Lagos spinach (Celosia argentea L.) as affected by different tillage methods and plant spacing. The experiment was a Randomized Complete Block Design (RCBD) involving twelve treatments, replicated three times. The plot size used was 2 m × 3 m with 1 m path ways between plots and 1 m between replicates. The treatments were different plant spacing (15 cm × 30 cm, 30 cm × 30 cm, 45 cm × 30 cm and 60 cm × 30 cm) and tillage methods (raise bed, ridges and flatbed). The result showed that the plants from raised bed at spacing of 30 cm × 30 cm (111,111 plants per ha) gave the highest response in terms of average growth parameters that were considered at 7 WAP and the yield value after harvesting at 8th week. The spacing of 30 cm × 30 cm from raised bed gave the highest fresh herbage yield of the Celosia planted.

Spilled polycyclic aromatic hydrocarbons (PAH), oils and dyes on water surface involve a big environmental risk. The clean-up of such pollutants consist a challenge from economic and environmental points of view. The absorbent of oils or PAH must have buoyancy, high uptake ratio oil/water, reusable and biodegradable. In this study, β-Cyclodextrin polymerized with beetroot fibers (Bio-polymer), was prepared and applied to remove oil, polycyclic aromatic hydrocarbons (PAH) and dyes from water. The Bio-polymer was prepared by copolymerization of beetroot with β-cyclodextrin polyurethane at 70°C. The prepared new material was characterized by means of granulometry, Scanning Electronic Microscopy and FTIR. The investigation into the use of cross-linked cyclodextrin polyurethanes with beetroot fibers as adsorbents for organic pollutants showed significant results. The effectiveness to eliminate dyes such as methylene blue and Rhoda mine B with concentrations around 100 ppm and 150 ppm respectively, was more than 99%, while the pyrene, which was chosen as an example among PAHs, showed a potential of elimination exceeding the 96 % for solutions of 30 ppm. Furthermore, spilled motor oils were tested and showed an efficacy exceeding the 90g oil per one g of biopolymers. The results indicated that the biopolymer developed in this study is a promising material for the removal of mixed pollutants from industrial wastewater and good sorbent for spilled oil clean-up applications. After the biopolymer’s application, yeast has been used for its biodegradation. The biodegradation, led to complete mineralization of organic contaminants and transform them into carbon dioxide, water, and inorganic compounds. The biopolymer weight polluted was reduced by biodegradation process to 15% of its initial mass.
多环芳烃(PAH)、油类和染料在水面上的泄漏具有很大的环境风险。从经济和环境的角度来看,清除这些污染物是一项挑战。油或多环芳烃的吸收剂必须具有浮力、高吸水比、可重复使用和可生物降解。本研究以甜菜根纤维(生物聚合物)为原料制备了β-环糊精,并将其用于去除水中的油脂、多环芳烃(PAH)和染料。甜菜根与β-环糊精聚氨酯在70℃下共聚制备了生物聚合物。用粒度法、扫描电镜和红外光谱对制备的新材料进行了表征。甜菜根纤维交联环糊精聚氨酯作为有机污染物吸附剂的研究取得了显著的成果。对浓度分别为100 ppm和150 ppm左右的亚甲基蓝和罗达矿B等染料的去除率超过99%,而以芘为例,对浓度为30 ppm的溶液的去除率超过96%。此外,对溢出的机油进行了测试,结果显示,每一克生物聚合物的功效超过了90克油。结果表明,本研究开发的生物聚合物是一种很有前途的去除工业废水中混合污染物的材料,也是一种很好的溢油清理吸附剂。生物聚合物应用后,利用酵母对其进行生物降解。生物降解导致有机污染物完全矿化,并将其转化为二氧化碳、水和无机化合物。受污染的生物聚合物经生物降解后重量降至初始质量的15%。

In this study, β-Cyclodextrin polymerized with beetroot fibers (Bio-polymer), was prepared and applied to remove oil, polycyclic aromatic hydrocarbons (PAH) and dyes from water. The Bio-polymer was prepared by copolymerization of beetroot with β-cyclodextrin polyurethane at 70°C. The prepared new material was characterized by means of granulometry, Scanning Electronic Microscopy and FTIR. The investigation into the use of cross-linked cyclodextrin polyurethanes with beetroot fibers as adsorbents for organic pollutants showed significant results. The effectiveness to eliminate dyes such as methylene blue and Rhoda mine B with concentrations around 100 ppm and 150 ppm respectively, was more than 99%, while the pyrene, which was chosen as an example among PAHs, showed a potential of elimination exceeding the 96 % for solutions of 30 ppm. Furthermore, spilled motor oils were tested and showed an efficacy exceeding the 90g oil per one g of biopolymers. The results indicated that the biopolymer developed in this study is a promising material for the removal of mixed pollutants from industrial wastewater and good sorbent for spilled oil clean-up applications. After the biopolymer’s application, yeast has been used for its biodegradation.

The research on utilization of spent mushroom substrate (SMS), vermicompost (VC), domestic compost (DC) and leachate (L) as inoculum of microorganisms in bioremediation of 30% oil sludge was conducted. The aim of this study was to obtain the most suitable inoculum in bioremediation of oil sludge. TPH and C/N ratios were analyzed on 15 days of interval, while Polycyclic Aromatic Hydrocarbon (PAH) and heavy metals were measured at the beginning (H-0) and the end of experiment (H-45) for 45 days of experiment. The additional parameters such as acidity (pH), temperature (°C), and humidity of medium (%) were measured. The results showed that all inoculums (SMS, VC, DC and L) affect the diminution of TPH as much as 27.7%, 20.9%, 24.8% and 24.20%, respectively. On the other hand, SMS and VC were able to decrease C/N ratio as much as 18% and 4%, respectively. By contrast, DC and L increased C/N ratio as much as 33% and 1.14%, respectively. In this study, inoculum of SMS and L were able to decrease Cr content (16% and 5.88%, respectively). However, Hg content diminished (29%) only in oil sludge medium with SMS inoculum. The PAH compound can be degraded by all types of inoculum with carbon chain ranged from C6-C54 into shorter carbon chain (C6-C30).

Hydrocarbons are a linear chain of carbon and hydrogen rich molecules serve as fuel from fossil source from the deep underground. Due to rapid population explosion followed by dynamic development in the Industrial sector, the Indian sub-continent is spending lot of money on energy to the Middle East Countries. Therefore, exploration of hydrocarbon rich regions within our country is one of the needful mission to cut-short the cost of fuel. As a novel theme, the hydrocarbon exploration study was carried out at five different locations each for freshwater site (Cauvery Riverbed region) and Marine site (Chennai Coastal region). About 100 g of soil samples from ten different sampling sites were collected by digging the ground up to three feet deep in both the riverbed and marine coastal sites. Then the soil samples were analyzed for different physio-chemical parameters such as pH, moisture content, nitrogen, potassium, sodium, magnesium phosphorous, total organic carbon, Sulphur, manganese, zinc, copper, molybdenum and nickel. For hydrocarbon analysis, the soil samples were subjected to hydrocarbon extraction by Soxhlet extraction method and analyzed by GC-MS by using standards for polyaromatic hydrocarbons including Naphthalene, Acenaphthylene, 2-Bromo-Naphthalene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Pyrene, Fluoranthene, Chrysene, Benz [a] anthracene, Benzo [b] fluoranthene, Benzo [ghi] perylene, Dibenz [a,h] anthracene and Indeno [1,2,3-cd] pyrene. The final result confirms that the hydrocarbon content was high in the soil samples of Chennai Coastal sites than the Cauvery freshwater riverbed regions. This may be due to high biochemical depositions of dead particles and algae in the sediments of marine coastal regions for a very long period. And this is a preliminary study to explore hydrocarbons in the soil sediments by exploring hydrocarbons from small pits as biochemical markers.
碳氢化合物是一种富含碳和氢的线性分子链,从地下深处的化石资源中作为燃料。由于人口快速爆炸以及工业部门的蓬勃发展,印度次大陆正在向中东国家投入大量资金购买能源。因此,勘探我国的油气富集区是降低燃料成本的必要任务之一。作为一个新的主题,油气勘探研究在五个不同的地点进行,分别是淡水地点(Cauvery河床地区)和海洋地点(Chennai沿海地区)。从10个不同的采样点收集了大约100克的土壤样本,这些样本是通过在河床和海洋沿岸地点挖掘3英尺深的地面收集的。然后分析土壤样品的不同理化参数,如pH、含水量、氮、钾、钠、镁、磷、总有机碳、硫、锰、锌、铜、钼和镍。碳氢化合物分析采用索氏萃取法提取,并采用气相色谱-质谱联用法对土壤样品进行多芳香烃(萘、苊、2-溴-萘、苊、芴、菲、蒽、芘、氟蒽、芘、苯并[a]蒽、苯并[b]氟蒽、苯并[ghi]苝、二苯并[a,h]蒽、茚地诺[1,2,3-cd]芘)标准进行分析。最终结果证实,金奈沿海地区土壤样品的碳氢化合物含量高于科弗里淡水河床地区。这可能是由于在很长一段时间内,死颗粒和藻类在海洋沿海地区的沉积物中大量生化沉积所致。这是一个初步的研究,通过从小坑中寻找碳氢化合物作为生物化学标记来探索土壤沉积物中的碳氢化合物。
