This book presents research on biomass pretreatments, which are a fundamental part of bioethanol fuel production to make biomass more accessible. This book also includes an introductory section on the bioethanol fuels. Bioethanol Fuel Production Processes. I: Biomass Pretreatments is the first volume in the Handbook of Bioethanol Fuels (Six-Volume Set). The primary pretreatments at the macro level are the biological chemical, hydrothermal, and mechanical pretreatments of the biomass. It also has an introductory section on the biomass pretreatments at large for bioethanol fuel production. The major pretreatments at the micro level are the enzymatic and fungal pretreatments of the biomass as the biological pretreatments, acid, alkaline, ionic liquid, and organic solvent pretreatment pretreatments of the biomass as the chemical pretreatments, steam explosion and liquid hot water pretreatments of the biomass as the hydrothermal pretreatments, and milling, ultrasonic, and microwave pretreatments of the biomass as the mechanical pretreatments. The first volume also indicates that a wide range of pretreatments stand alone or in combination with each other fractionate the biomass to its constituents of cellulose, lignin, and hemicellulose and improve both sugar and bioethanol fuel yield, making this bioethanol fuel more competitive in relation to crude oil- and natural gas-based fossil fuels. This first volume is a valuable resource for the stakeholders primarily in the research fields of energy and fuels, chemical engineering, environmental science and engineering, biotechnology, microbiology, chemistry, physics, mechanical engineering, agricultural sciences, food science and engineering, materials science, biochemistry, genetics, molecular biology, plant sciences, water resources, economics, business, management, transportation science and technology, ecology, public, environmental and occupational health, social sciences, toxicology, multidisciplinary sciences, and humanities among others.

Advances in 2nd Generation of Bioethanol Production presents a comprehensive overview of technologies and strategies for the conversion of lignocellulosic biomass. This includes issues like sustainable production, environmental and economic benefits, and the main hurdles for upscaling and achieving commercial viability. The book assesses the current biomass conversion technologies, their readiness level for commercial production, and applications of bioethanol in bioenergy and chemical feedstock. The essential conversion process of 2nd generation biofuels, including feedstock composition and pretreatment, is then broken down, with special focus on advantages and pitfalls of each feedstock and process. It also explores the advances and challenges of bioprocessing, hydrolysis technologies and simultaneous fermentation of pentose and hexose. Finally, it presents the current status and bottlenecks for industrial production of bioethanol, as well as its future prospects. Its interdisciplinary approach, drawing upon plant biology, chemistry, biochemistry, microbiology, and genetics, makes Advances in 2nd Generation of Bioethanol Production a must-have reference for researchers in academia and industry R&D. It allows them to compare challenges and opportunities of new technologies and identify the gaps where new technology is needed. Practitioners in the industry also benefit from the information on working principles, design and control of the bioethanol production process, highlighting areas where technology innovation and investment should be placed.

Bioethanol and Beyond: Advances in Production Process and Future Directions discusses the advances in the production process of bioethanol, ranging from first to fourth generation bioethanol. Bioethanol is currently applied besides simple fuels (biofuel): it is mixed with other fuels, such as gasoline and diesel, and used for generating renewable fuels, such as hydrogen. Advances in the industrial bioethanol (first and second generation) chain point towards the co-energy generation, in situ, and the possibility of generating outside the industry via energetic densification of the residues. A biorefinery is suggested as a strategy to use the industrial residues by amplifying the products portfolio and, thus, collaborating with the process feasibility. The book covers the technological possibilities to produce bioethanol. These processes include the second generation with the use of structural sugars from the plant cell wall and residues from algae (third and fourth generation bioethanol). The fermentation process and contamination in the industrial fermentation is presented, as well as strategies for its control. Pretreatment technologies, enzymatic hydrolysis technologies, and the search for enzymes are described based on recent developments and finds. When it comes to commercialization, technical-analytical standards have been developed in order to control bioethanol quality, contributing to overcome technical barriers and providing product reliability. This book covers the most important tasks in the production process and future directions for the uses, which is a very useful source of information for everything involved in bioethanol science. In particular, this book will answer the questions of students and researches regarding bioethanol production process, as well as professionals in the industry supply chain.
