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 first delves into 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 their product distribution. The author goes on to address 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.
Rotary Kilns—rotating industrial drying ovens—are used for a wide variety of applications including processing raw minerals and feedstocks as well as heat-treating hazardous wastes. They are particularly critical in the manufacture of Portland cement. Their design and operation is critical to their efficient usage, which if done incorrectly can result in improperly treated materials and excessive, high fuel costs. This professional reference book will be the first comprehensive book in many years that treats all engineering aspects of rotary kilns, including a thorough grounding in the thermal and fluid principles involved in their operation, as well as how to properly design an engineering process that uses rotary kilns.
