Various enzymatic loadings (15–20 FPU/g biomass) and concentrations of yeast extract (0.25–1 g/L) were studied during the enzymatic hydrolysis. Optimization of yeast extract insertion was performed to simultaneously facilitate the infusion of cellulolytic enzymes into the pores of the pre-treated bagasse concomitantly inhibiting enzyme absorption caused by residual lignin.

Saad ,&nbsp;Adilson R. Gonçalves","doi":"10.1016/j.biombioe.2024.107426","DOIUrl":"10.1016/j.biombioe.2024.107426","url":null,"abstract":"&lt;div&gt;&lt;div&gt;Renewable alternatives to fossil fuels are now a worldwide effort, and biofuels can play an essential role in a sustainable energy matrix. The great potential of lignocellulosic biomass as feedstock for bioethanol production has been underexplored due to technological barriers and the costs involved. However, a new chapter in this history has been written recently after eight different biomass-to-ethanol processes achieved the industrial scale, leading bioethanol technologies to a new step of maturity due to challenges faced and lessons learned. The pretreatment of biomass has been recognized as the most complex step in the cellulosic ethanol production processes and the reason for the failure of some industrial initiatives. Pretreatment represents an essential process to prepare lignocellulosic material for subsequent hydrolysis and fermentation, and this review aims to describe the early and recent efforts to scale-up pretreatment systems and the current challenges of pretreatment operations. Since the early 2010s, a global running for cellulosic ethanol resulted in eight industrial facilities around the world; agricultural residues like corn stover, corn cob, wheat straw, sugarcane bagasse, and sugarcane straw were used by POET-DSM, Raízen, Beta Renewables, GranBio, Abengoa, DuPont, Clariant, and Longlive Bio-tech as feedstock for bioethanol production. Pretreatment technologies, including diluted acid, steam explosion, dilute ammonia, and mechanical refining, were then experienced industrially through batch or continuous systems performed in one or two conversion stages. The pretreatment systems employed by each cellulosic biorefinery are analyzed in this review, and the process conditions and strategies applied are discussed based on public information available. Furthermore, a historical background of the early developments of acid hydrolysis of cellulose and the transition to the modern pretreatment concept is provided. Typical batch reactors employed during the 1900s were replaced by continuous reactors aiming for high productivity. An overview of digesting systems used by the pulp and paper industry is explored, which were initially developed for pulping and recently adapted to perform biomass pretreatment. Special attention is paid to describing vertical and horizontal continuous digesters and mechanical disc refiners, the leading equipment used in industrial pretreatment systems. Additionally, current pretreatment challenges are discussed based on pilot and industrial experience. Biorefineries faced low throughput capacity due to unstable operation and high wear damage to equipment caused by mineral impurities. The impact of feedstock quality and preconditioning processes on pretreatment operation is also reviewed. Feedstock collection, storage, and cleaning have been considered critical operations for a successful pretreatment process; best practices from the non-wood pulping industry are analyzed, providing an important ref","PeriodicalId":253,"journal":{"name":"Biomass & Bioenergy","volume":"190 ","pages":"Article 107426"},"PeriodicalIF":5.8,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142434522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system design and process simulation were implemented via Aspen plus, and the thermodynamic performance of the system was analyzed. Meanwhile, a life cycle environmental assessment under different conditions was performed using SimaPro. Based on the fixed reaction concentration, results of thermodynamic analysis reveal that the energy efficiency and exergy efficiency of the system are related to temperatures of the first-stage gasification reactor and the second-stage oxidation reactor. When temperatures of FGR and SOR are 603°C and 833°C respectively, the system could reach the highest hydrogen production. Moreover, the energy efficiency and exergy efficiency could reach 54.9 % and 56.2 % respectively, while changes of temperatures of the first-stage oxidation reactor and the second-stage gasification reactor have no effect on efficiency. In addition, the maximum recoverable energy loss is induced by the waste heat of the effluent from Cooler, indicating the path of system optimization. By using organic Rankine cycle, the energy efficiency and exergy efficiency could reach 57.7 % and 59.3 % respectively. Meanwhile, the data from SimaPro shows LCI and LCIA of the system, which identified the main environmental burdens. Overall, this work has great advantages in terms of thermodynamics and environmental impact, while it faces both opportunities and challenges.

In this study, metal oxides and ZSM-5 were chosen as catalysts to further extend the advantages of selective catalysis. In this paper, microscopic and bench-scale experiments for the conversion of biomass to high-yield aromatics using ZSM-5 and metal oxide catalysts were systematically investigated. In a dual catalyst pyrolysis study involving ZSM-5 and metal oxides (CaO, MgO, NiO, MoO₃), PY-GC-MS, Tube Furnace experiments were used to evaluate various catalyst layouts. The influence of catalyst dose on three-phase product yields was examined in a bench-scale fixed bed reactor employing the optimal architecture and metal oxides. The findings revealed that the dual-catalyst arrangement was critical to improving bio-oil quality. The best yield (50.02 %) of monocyclic aromatic hydrocarbons (MAHs) was produced by combining Miscanthus with the metal oxides and then separating with ZSM-5. Among the four metal oxides, CaO had the greatest synergistic effect on MAHs and selectivity. The inclusion of CaO decreased the concentration of several oxygenated compounds, particularly the suppression of furans, phenols, and acids, which was extremely advantageous for improving bio-oil quality.
