Freshly harvested woody biomass has a significant amount of weight in water. Wood chips need to be ground and dried to reduce the amount of water entering pyrolysis. The larger the wood chip, the more energy needed to dry it. Reducing water in pyrolysis products increases the quality and energy value of the bio-oil. Abstract. Virtually any form of biomass can be considered for fast pyrolysis. Most work has been performed on wood, because of its consistency and comparability between tests. However, nearly types of biomass have been tested, ranging from agricultural wastes such as straw, olive pits, and nut shells to energy crops such as miscanthus Cited by: This paper analyzes the main kinetic features of biomass pyrolysis, devolatilization, and the gas phase reactions of the released species. Three complex steps are faced in sequence: the characterization of biomasses, the description of the release of the species, and finally, their chemical evolution in the gas phase. Biomass is characterized as a mixture of reference constituents: cellulose Cited by:

For the hydrogen-production scenario, 38% of the bio-oil is reformed to produce 1, kg/hour of hydrogen. • Pyrolysis is thermal decomposition occurring in the absence of oxygen – Energy required to raise temperature to start process (F) may be external or internal (part of biomass load) • It is the first step of combustion and gasification • Family of related processes including: – Slow pyrolysis . This paper analyzes the main kinetic features of biomass pyrolysis, devolatilization, and the gas phase reactions of the released species. Three complex steps are faced in sequence: the characterization of biomasses, the description of the release of the species, and finally, their chemical evolution in the gas phase. Biomass is characterized as a mixture of reference constituents: cellulose Cited by: Biomass pyrolysis is a fundamental thermochemical conversion process that is of both industrial and ecological importance. Freshly harvested woody biomass has a significant amount of weight in water. Wood chips need to be ground and dried to reduce the amount of water entering pyrolysis. The larger the wood chip, the more energy needed to dry it. Reducing water in pyrolysis products increases the quality and energy value of the bio-oil. Biomass can be converted into heat and electricity in a number of ways. Depending on its source, these processes include: combustion, pyrolysis, gasification, liquefaction, anaerobic digestion or fermentation. Thermo-chemical processes convert biomass into higher-value or .
