In anoxic circumstance, the pyrolysis or torrefaction of biomass can be induced under the microwave irradiations. Thus various valued products can be generated, such as biofuels and green materials. Different from the conventional heating, the fast and focused microwave heating provides higher thermal and energy efficiency. These advantages promote the productivities of gas and liquid products that can be regarded as alternative fuels. This project will study the reaction kinetics, reaction mechanism, and product characteristics of microwave pyrolysis and torrefaction. Effects of microwave absorber, catalyst addition, and reaction atmosphere on product distribution and process productivity will be studied, and the basic characteristics and thermo-chemical properties of various biomass feedstocks will be researched as well. This project will discuss the reaction conditions, productivity, product characteristics, and technology feasibility of the biorefinery process based on microwave pyrolysis. This study will attempt to obtain the best products and the highest productivity by various methods, including atmosphere control and process optimization. This study will prepare novel catalysts using microwave heating, and then test their effects on catalytic microwave pyrolysis. The adsorption of carbon dioxide on the biochar produced by the microwave torrefaction will be studied to maximize the adsorption capacity and to be compared with the biochar produced by conventional heating. The life cycle assessment of a biorefinery process based on microwave pyrolysis will be studied to evaluate the environmental impacts and benefits of microwave pyrolysis. There has been no study on microwave pyrolysis biorefinery yet so far. This project will attempt to develop a bioenergy technology with high efficiency, and thus to promote the localized researches and developments of the bioenergy technologies and to replace the traditional fuels.微波加熱裂解生質能源催化吸附生命週期評估Microwave heatingPyrolysisBioenergyCatalysisAdsorptionLife cycle assessment
