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 ultrasound and microwave 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 Ultrasound” and “Production of Biofuels and Chemicals with Microwave” 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 “Ultrasound” provides current research advances and prospects in mechanistic principles of acoustic cavitation in sonochemistry, physical and chemical mechanisms in biofuel synthesis, reactor design for transesterification and esterification reactions, lipid extraction from algal biomass, microalgae extraction, biodiesel and bioethanol synthesis, practical technologies and systems, pretreatment of biomass waste sources including lignocellulosic materials, manures and sludges for biogas production, vibration-assisted pelleting, combined chemical-mechanical methods, valorization of starch-based wastes and techno-economic methodology. 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 “Ultrasound” and “Microwave” 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.

This book provides state-of-the-art reviews, current research, prospects and challenges of the production of biofuels and chemicals such as furanic biofuels, biodiesel, carboxylic acids, polyols and others from lignocellulosic biomass, furfurals, syngas and γ-valerolactone with bifunctional catalysts, including catalytic, and combined biological and chemical catalysis processes. The bifunctionality of catalytic materials is a concept of not only using multifunctional solid materials as activators, but also design of materials in such a way that the catalytic materials have synergistic characteristics that promote a cascade of transformations with performance beyond that of mixed mono-functional catalysts. This book is a reference designed for researchers, academicians and industrialists in the area of catalysis, energy, chemical engineering and biomass conversion. Readers will find the wealth of information contained in chapters both useful and essential, for assessing the production and application of various biofuels and chemicals by chemical catalysis and biological techniques.

Biofuels are a viable alternative to petroleum-based fuel because they are produced from organic materials such as plants and their wastes, agricultural crops, and by-products. The development of cutting-edge technology has increased the need for energy significantly, which has resulted in an overreliance on fossil fuels. Renewable fuels are an important subject of research because of their biodegradability, eco-friendliness, decrease in greenhouse gas (GHG) emissions, and favorable socioeconomic consequences to counteract imitations of fossil fuels. Different extraction techniques are used for the production of biofuel from renewable feedstocks. Biodiesel is a promising biofuel which is produced by transesterification of plant-based oils. Extraction of oil includes old traditional methods, solvent extraction, mechanical extraction, microwave-assisted and ultrasonic-assisted methods. Many innovative techniques are also used to overcome the limitations of conventional methods. Microwave-assisted, ultrasonic-assisted is some of the new techniques which include the pre-treatment of the raw material using either ultrasonic waves or radio waves which helps in increasing the efficiency of the extraction of oil and improves the final quality of the oil. Written and edited a team of experts in the field, this exciting new volume covers all of these technologies with a view toward giving the engineer, scientist, or other professional the practical solutions for their day-to-day problems. It also contains the theory behind the practical applications, as well, making it the perfect reference for students and engineers alike. Whether for the veteran engineer or scientist, the student, or a manager or other technician working in the field, this volume is a must-have for any library.

This work aimed to improve the understanding of the use of microwaves and ultrasound for chemical processes. Using biodiesel production as the case for study, the non-linear effects of high intensity ultrasonics, electromagnetic loss, and microwave heating were explored. Cavitation and atomization phenomena were used to describe the process of ultrasonic emulsification. The dielectric loss mechanisms pertinent to the biodiesel production materials were described as the connection to between the effects of ultrasonic emulsification and microwave heating. Superheating and anisothermal heating phenomena were identified as the specific advantages afforded by microwave heating. High intensity ultrasonics was found to be capable of creating emulsions of biodiesel reactants with uniform dispersed phase droplets. Through optical microscopy, the ability to control the dispersed phase droplet size by altering the frequency and intensity of ultrasound was confirmed. This ultrasonic technique was investigated by measuring complex permittivity of the emulsions from 500 MHz and 5 GHz. The dielectric loss of emulsions consisting of methanol and soybean oil indicated that ultrasonic treatments could be used to alter the microwave absorption. Microwave heating tests of ultrasonically formed emulsions confirmed the permittivity results practically. The superheated boiling point of methanol and heating rate of methanol was extended to higher temperatures and rates in ultrasonically formed emulsions. Microwave heating of ultrasonically mixed emulsions was shown to result in faster transesterification relations than microwave heating of conventionally mixed emulsions. Finally, utilizing ultrasonics to optimize microwave absorption was shown capable of transesterification without catalyst.
