This volume focuses on technological advances relevant to establishing biofuels as a viable alternative to fossil fuels by overcoming current limitations. The progressive depletion of fossil fuels due to their large-scale utilization and their environmental consequences, notably global warming, increase the need for sustainable and cleaner energy options. Renewable biofuels – like biohydrogen, biomethane, biogas, ethanol and butenol – represent attractive energy sources to meet the growing global demand, thanks to sustainable and cost-efficient production approaches based on cellulosic biomass. Currently, the commercialization of these technologies is hindered by technical and economic limitations, such as biomass complexity and pre-treatment, enzyme hydrolysis, production efficiency as well as storage and cost. As such, this book presents economically viable and sustainable approaches to improve existing biofuel technologies and appeals to anyone with an interest in biofuels as renewable energy options and their practical implementation.

This book provides in-depth coverage on the latest concepts, systems, and technologies that are being utilized in biorefineries for the production of biofuels and value-added commodities. Written by internationally recognized experts, the book provides a comprehensive overview of pretreatment technology for biorefineries and biofuels, enzymatic hydrolysis and fermentation technology for biofuel production, and lignin valorization for developing new products from waste lignin. The book will be a valuable resource for researchers and professionals working in process engineering, product engineering, material science, and systems and synthetic biology in the fields of biorefining, biofuel, biomaterials, environmental waste utilization, and biotechnology.

This book examines the key aspects that will define future sustainable energy systems: biofuels, green nanomaterials and the production of bioethanol and bio-hydrogen from bio-waste. Bio-based fuels are the future energy carriers for internal combustion engines as they have lower environmental impact and higher efficiency. The book clearly illustrates the requirement for a unified engineering approach based on solid mathematical and engineering principles. Aside from the ecological advantages, support for sustainable energy can help the socioeconomic situation of developing countries by providing a consistent supply of new energy along with the generation of new job opportunities. The sustainable energy applications and existing contextual investigations provide useful guidance for the broad comprehension of the significance of sustainable energy. Technical topics discussed in the book include: Thermochemical Conversion process; Catalytic conversion process; Rankine cycle; Nanomaterials;

This second volume in the Advances in Biofeedstocks and Biofuels series focuses on the latest and most up-to-date technologies and processes involved in the production of biofuels. Biofuels production is one of the most extensively studied fields in the energy sector that can provide an alternative energy source and bring the energy industry closer to sustainability. Biomass-based fuel production, or renewable fuels, are becoming increasingly important as a potential solution for man-made climate change, depleted oil reserves, and the dangers involved with hydraulic fracturing (or "fracking"). The price of oil will always be volatile and changeable, and, as long as industry and private citizens around the world need energy, there will be a need for alternative energy sources. The area known as "biofuels and biofeedstocks" is one of the most important and quickly growing pieces of the "energy pie." Biofuels and biofeedstocks are constantly changing, and new processes are constantly being created, changed, and improved upon. The area is rapidly changing and always innovative. It is important, therefore, that books like the volumes in this series are published and the information widely disseminated to keep the industry informed of the state-of-the-art. This second volume in the Advances in Biofeedstocks and Biofuels series focuses on the production of biofuel, covering all of the major biofuels, such as biodiesel, biohydrogen, bioethanol, and others. This engaging text touches on all of the most important new processes and technologies, providing the most up-to-date coverage of the science available to industry. It is a must-have for any engineer or scientist working with biofuel technology.

Sets the stage for large-scale production of biofuels and bio-based chemicals In response to diminishing supplies as well as the environmental hazards posed by fossil fuels and petrochemicals, interest and demand for green, sustainable biofuels and bio-based chemicals are soaring. Biomass may be the solution. It is an abundant carbon-neutral renewable feedstock that can be used for the production of fuels and chemicals. Currently, biorefineries use corn, soybeans, and sugarcane for bioethanol and biodiesel production; however, there are many challenges facing biorefineries, preventing biomass from reaching its full potential. This book provides a comprehensive review of bioprocessing technologies that use lignocellulosic biomass for the production of biofuels, biochemicals, and biopolymers. It begins with an overview of integrated biorefineries. Next, it covers: Biomass feedstocks, including sugar, starch, oil, and energy crops as well as microalgae Pretreatment technologies for lignocellulosic biomass Hydrolytic enzymes used in biorefineries for the hydrolysis of starch and lignocelluloses Bioconversion technologies for current and future biofuels such as ethanol, biodiesel, butanol, hydrogen, and biogas Specialty chemicals, building block chemicals, and biopolymers produced via fermentation Phytochemicals and functional food ingredients extracted from plant materials All the chapters have been written and edited by leading experts in bioprocessing and biorefining technologies. Contributions are based on a thorough review of the literature as well as the authors' firsthand experience developing and working with bioprocessing technologies. By setting forth the current state of the technology and pointing to promising new directions in research, Bioprocessing Technologies in Biorefinery for Sustainable Production of Fuels, Chemicals, and Polymers will enable readers to move towards large-scale, sustainable, and economical production of biofuels and bio-based chemicals.

This book provides a single-source reference to green technologies in advanced biofuel technology. The main focus is on the description of the state of the art in catalytic processes for the "green" production of biofuels. The authors describe two different, practical approaches for catalysts, which allow for effective and easy separation of the catalyst by simple filtration, and enable reuse for several cycles. Readers will gain understanding as to the mechanisms involved in the synthesis and structure formation of the catalyst, in order to maximize yield of biodiesel production. The authors also address the question of how catalytic material should be distributed inside a porous support to obtain optimal performance. The effects of physicochemical and operating parameters are analyzed to gain insight into the underlying phenomena governing the performance of optimally designed catalysts.“br>
