Abstract

The invention discloses an auxiliary agent for biomass treatment and a biomass gasification treatment method. The auxiliary agent comprises a component A, a component B and a component C, wherein thecomponent A comprises Lewis acid and one or more of optional organic acid and protonic acid, the component B is a salt of group IA, IIA and IIIA metals and ammonium, and the component C is one or moreof manganese acetate, manganese sulfate and manganese nitrate. The gasification treatment method comprises the following steps: mixing a biomass raw material and an auxiliary agent, and carrying outa reaction to obtain a volatile component and biological semicoke; performing a reaction on the solid-phase materials obtained after gas-solid separation of volatile components and the biological semicoke respectively in a biological coke microwave gasification reactor to obtain crude synthesis gas and activated carbon; and feeding the synthesis gas obtained after gas-solid separation of the crudesynthesis gas into a purification reactor to be treated, thus preparing purified synthesis gas. According to the biomass gasification treatment method and system, the yield of the synthesis gas can be increased, and the tar content in the obtained synthesis gas product is low.

Description

technical field [0001] The invention belongs to the field of biomass processing, and relates to a biomass gasification method, in particular to a biomass microwave gasification method. Background technique [0002] my country is rich in biomass resources, but the utilization methods are backward, and the energy utilization efficiency is low, resulting in a serious waste of biomass resources. Research and development of clean and efficient biomass indirect liquefaction technology has become one of the important contents to solve the current shortage of petroleum resources, develop biomass energy economy and reduce environmental pollution. Biomass indirect liquefaction technology essentially decomposes biomass into small molecular substances mainly composed of syngas, and then undergoes further chemical conversion into high-quality fuels and high value-added chemicals. However, the immaturity of biomass pyrolysis and gasification technology, low gasification efficiency, the p...
