Experiments on purification technologies for the conversion of cornstalk biomass into the industrial product were made to produce cornstalk gas in the down-flow fixed by the gasifier. The experiment focused on the technical procedures for deoxygenation. catalytic cracking of tar, hydrogenation, etc. Quality straw syngas was produced for methanol synthesis. The catalysis of methanol synthesis for the production of cornstalk syngas was earned out in a tubular-flow integral and isothermal reactor under the pressure of 5MPa over Cu-based catalyst C301 (particle size: 0.833mm×0.351mm), a catalyst made in China. Thirty-three sets of test data were obtained.
