Summary: | The invention belongs to the technical field of biomass treatment, and particularly relates to a process for preparing light aromatic hydrocarbon and co-producing methanol through biomass microwave conversion acetylene trimerization, which comprises the following steps: (1) crushing and pretreating biomass; (2) carrying out anaerobic fermentation on the pretreated biomass particles to generate methane and carbon dioxide; (3) drying, purifying and separating methane and carbon dioxide; (4) performing microwave reaction on methane to obtain acetylene, and performing trimerization reaction on the obtained acetylene to obtain light aromatic hydrocarbon; and performing methanol synthesis reaction on the hydrogen generated in the step (4) and the carbon dioxide separated in the step (3) to obtain methanol. According to the process, anaerobic fermentation, microwave conversion, acetylene trimerization and methanol synthesis processes are coupled, biomass is directly converted into light aromatic hydrocarbon compound |
