摘　　要：采用热化学方法将秸秆类生物质裂解为生物质燃气,并对该燃气进行优化试验,制备出合成气,在等温积分反应器中,采用5MPa压力和国产C301铜基催化剂(粒度为0 833mm×0 351mm),对玉米秸秆合成气进行催化合成甲醇试验研究,研究结果表明:合成甲醇的最佳温度和流量分别为230℃,0 98mol·h-1,最大甲醇时空收率为0In order to research to change the agricultural residues into the industrial product, pyrolysis test of cornstalk biomass fuel gas by the thermochemical method, and the optimum tests were performed through which the synthesis gas was produced from fuel gas cornstalk. The catalytic test of methanol sythesis for biomass syngas over a domestic Cu-based catalyst C301(Particle size is Φ0.833 mm×0.531 mm)were carried out in an integral and isothermal reactor under the pressure of 5MPa. The test results showed that the optimum operating temperature and the flow of the methanol synthetic was 230℃,0.98 mol·h^(-1), and the maximum methanol time-space yield rate was 0.238 1 kg·kg^(-1)·h^(-1).
