This book presents a collection of studies on state-of-art techniques for converting biomass to chemical products by means of pyrolysis, which are widely applicable to the valorization of biomass. In addition to discussing the fundamentals and mechanisms for producing bio-oils, chemicals, gases and biochar using pyrolysis, it outlines key reaction parameters and reactor configurations for various types of biomass. Written by leading experts and providing a broad range of perspectives on cutting-edge applications, the book is a comprehensive reference guide for academic researchers and industrial engineers in the fields of natural renewable materials, biorefinery of lignocellulose, biofuels, and environmental engineering, and a valuable resource for university students in the fields of chemical engineering, material science and environmental engineering.

Conversion of biomass into chemicals and biofuels is an active research and development area as trends move to replace traditional fossil fuels with renewable resources. By integrating processing methods with microwave and ultrasound irradiation into biorefineries, the time-scale of many operations can be greatly reduced while the efficiency of the reactions can be remarkably increased so that process intensification can be achieved. “Production of Biofuels and Chemicals with Microwave” and “Production of Biofuels and Chemicals with Ultrasound” are two independent volumes in the Biofuels and Biorefineries series that take different, but complementary approaches for the pretreatment and chemical transformation of biomass into chemicals and biofuels. The volume “Microwave” provides current research advances and prospects in theoretical and practical aspects of microwave irradiation including properties, effects and temperature monitoring, design of chemical reactors, synergistic effects on combining microwave, ultrasound, hydrodynamic cavitation and high-shear mixing into processes, chemical and catalytic conversion of lignin into chemicals, pyrolysis and gasification, syngas production from wastes, platform chemicals, algal biodiesel, cellulose-based nanocomposites, lignocellulosic biomass pretreatment, green chemistry metrics and energy consumption and techno-economic analysis for a catalytic pyrolysis facility that processes pellets into aromatics. Each of the 12 chapters has been peer-reviewed and edited to improve both the quality of the text and the scope and coverage of the topics. Both volumes “Microwave” and “Ultrasound” are references designed for students, researchers, academicians and industrialists in the fields of chemistry and chemical engineering and include introductory chapters to highlight present concepts of the fundamental technologies and their application.

Pyrolysis of Biomass for Fuels and Chemicals provides a thorough overview of thermochemical conversion of biomass to fuels and chemicals via the pyrolysis platform. The book covers the principles underlying pyrolysis of biomass from the chemical engineering perspective. It discusses thermal-only pyrolysis, the traditional pyrolysis process under inert atmosphere with no catalyst, and the role of catalytic pyrolysis and tail gas reactive pyrolysis in resolving the instability issues associated with product distribution. The addresses condensed phase upgrading where the oil produced can be upgraded for stability or hydrogenated to drop-in transportation fuels, as well as feedstock selection, including opportunity fuels/feedstocks. Finally, pilot and demonstration scale projects from around the world are examined, and some immediate applications of pyrolysis oils in combustion systems are analyzed. Engineering researchers and professionals in the bioenergy, biochemical, and petrochemical fields find in this book a complete resource for understanding the relationships between possible technologies, applications, costs, and products value, as they tackle the challenges for large scale adoption of pyrolysis for the production of 2nd generation biofuels and biochemicals. PhD students in areas of energy, chemical, mechanical, and materials engineering will also benefit from fundamental and applied research in a concise format that can save them time and serve as a reference through bioenergy conversion courses. Covers thermal only pyrolysis, catalytic pyrolysis, and tail gas reactive pyrolysis Examines the relationships between technologies, applications, costs and products value, and end-use Offers a cradle-to-grave approach that includes coverage of feedstocks, their compositional traits, and how they affect conversion technologies with regard to yields, quality of pyrolysis fuel intermediates, and subsequent upgrade to drop-in fuels
