Microwave is an alternative method which can rapidly pyrolyze biomass by thermal treating, and produce clean syngas and bio-oil products. In this research, the wood particles microwave pyrolysis process was proposed for preparing bio-oil and syngas production. The wood particles were first pyrolyzed by microwave reactor in the process, and then the bio-oil products were separated by cyclone separator and multi-phase separator, syngas products were prepared by steam reforming reactor and absorption tower. Kinetics for larch microwave thermogravimetry reactions were proposed and correlated with lab-scale experiments; the microwave pyrolysis process was simulated in Aspen HYSYS, and the results showed that when pyrolysis reaction temperature and microwave power were 900℃ and 2.0 kW respectively, the maximum bio-oil and syngas production can be achieved. The H/CO and CO content in syngas which can be used in chemical processes such as Fischer-Tropsch synthesis, can be controlled by the molar ratio function of steam and pyrolysis gas.
微波是一种可通过热处理快速热解生物质的替代方法，能够生产清洁合成气和生物油产品。本研究提出了木材颗粒微波热解工艺以制备生物油和合成气。在此过程中，木材颗粒首先通过微波反应器进行热解，然后生物油产品通过旋风分离器和多相分离器进行分离，合成气产品则通过蒸汽重整反应器和吸收塔制备。提出了落叶松微波热重反应动力学并与实验室规模实验相关联；在Aspen HYSYS中对微波热解过程进行了模拟，结果表明，当热解反应温度和微波功率分别为900℃和2.0kW时，可实现生物油和合成气的最大产量。可用于费托合成等化学过程的合成气中的H/CO和CO含量，可通过蒸汽与热解气的摩尔比函数进行控制。
