摘　　要：生物质能是一种可再生能源,为了研究秸秆类生物质转化为燃料甲醇以有效地利用生物质能,采用热化学方法在下吸式固定床气化炉中生产低热值燃气,对该燃气进行脱硫、脱氧、焦油催化分解、纯化、配氢等优化试验,制备出秸秆合成气。在直流流动等温积分反应器中进行了催化合成甲醇的试验,在235℃和5MPa条件下进行了催化剂种类及粒度对合成甲醇的影响试验。试验结果表明:合成甲醇的适宜催化剂型号为C301,最优化颗粒粒度为0.833mm×0.351mm,该研究为生物质(秸秆)气催化合成甲醇的深入研究提供了基础数据。Biomass energy is a kind of renewable and potential resource.In order to study the conversion of stalk-type biomass（the agricultural residues） into fuel methanol and effectively utilize biomass energy,the low-heat-value cornstalk gas was produced by means of the thermo-chemical method in a down-flow fixed bed gasifier.The cornstalk gas was purified and the technical procedures such as desulfurization,catalytic cracking of tar,deoxygenation,purification and hydrogenation were performed.Under the optimum test conditions,the cornstalk syngas was prepared.The catalytic experiments of methanol synthesis with cornstalk syngas as feedstock were carried out in a tubular flow integral and isothermal reactor.The effect of the catalyst types,catalyst particle size was investigated at 235 ℃ under the pressure of 5 MPa.The experimental results indicated that the proper catalyst for the synthetic reaction was C301 and the optimum catalyst size was 0.833 mm×0.351 mm.This study can provided basic data for further studies of methanol synthesis from biomass（cornstalk） gas.
