摘　　要：生物质能是一种可再生能源．为了实现秸秆类生物质合成燃料甲醇的工业转化,有效利用生物质能,对下 吸式固定床气化炉产生的低热值玉米秸秆燃气进行除氧、分解焦油和配氢等纯化试验,制备出合成甲醇的优质秸 秆合成气,在直流流动等温积分反应器中,使用国产C301铜基催化剂,催化剂粒度为20-40目(0．833 mm×0．351 mm),在5 MPa反应压力下,对玉米秸秆合成气进行催化合成甲醇试验研究,获得33套试验数据．试验结果表明, 低热值秸秆燃气通过适当处理,可直接合成甲醇,合成反应的适宜温度为230-250℃,适宜流量为0．8-1．0 mol／ h,较佳的甲醇时空收率为0．24 kg/(kgcat·h)．Biomass energy is a renewable resource. Experiments on purification technologies for the conversion of cornstalk biomass into the industrial product （ synthesis of fuel methanol） were made to produce cornstalk gas （ low heat value） 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 carried out in a tubularflow integral and isothermal reactor under the pressure of 5 MPa over Cu-based catalyst C301 （ particle size： 0. 833 mm ×0. 351 mm）, a catalyst made in China. Thirty-three sets of test data were obtained. The test resuits showed that the methanol could be synthesized directly from cornstalk gas （low heat value） through proper treatment. The proper operation temperature of the synthetic reaction was 230-250 ℃ ; the suitable flow of syngas was 0.8-1.0 mol/h ; and the better methanol time-space yield was 0.24 kg/（kgeat · h）.
