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.
