Therefore, the problems of waste treatment can be solved, and the produced bio-energy can lower the excessive demand of fossil fuels as well. The microwaves are a kind of electromagnetic waves, whose wavelengths are between 1 mm – 1 m, and the frequencies are between 300 MHz – 300 GHz. The microwaves own the characteristic of fast, uniform, and selective heating manner, so the microwave technologies have been widely applied to many different fields. This project is going to utilize the technology of microwave-induced pyrolysis and torrefaction. In the anoxic circumstance, a pyrolysis can occur among the biomass waste after the microwave irradiations. Thus some products valuable for energy can be generated. Different from the traditional manner of heating, the fast and focused microwave heating provides higher thermal efficiency and energy-usage efficiency. These advantages promote the productivities of gas and liquid products, which means the more gas and liquid fuels can be generated. By the control of reaction atmosphere and the addition of microwave absorber or catalyst, to optimize the operational conditions is supposed, to improve the qualities and productivities of products. The reaction kinetics analysis and the economic analysis are both planned to do to understand the mechanism of microwave-induced pyrolysis and torrefaction, and to assess the commercial feasibility. This project is also going to establish the critical parameters of operation and performance, which can be consulted by the following applications and developments. There are fewer applications of microwave-induced pyrolysis and torrefaction of biomass waste so far, both in overseas and domestic markets. By the execution of this project, to develop a treatment of high efficiency is expected, and thus to promote the localized researches and developments of the bio-energy technologies.生質廢棄物生質能源微波熱裂解焙燒biomass wastebio-energymicrowavepyrolysistorrefaction生質廢棄物微波誘發裂解之應用技術研發(II)
