Microwave pyrolysis of Biomass

By using microwave pyrolysis, almost half of lignocellulosic biomass can be converted into gas product, which is mainly composed of H2, CH4, CO, and CO2. Due to high H2and CO yields, the gas product of microwave pyrolysis has higher heating value than that of conventional pyrolysis. The addition of proper catalysts can provide substantial influence on the product selectivity of microwave pyrolysis. The gas and liquid yields as well as the heating performance of microwave pyrolysis can be dramatically promoted by adding catalysts. The activation energy and pre-exponential factor of microwave pyrolysis are much lower than those of conventional pyrolysis, revealing that the reaction kinetics for the two methods are different. According to the aforementioned literature results, microwave assisted pyrolysis should have a high potential for the production bioenergy and green materials from lignocellulosic biomass.
