摘　　要：生物质能是一种可再生能源,为了研究秸秆类生物质(农业废弃物)转化为燃料甲醇和生物质能的有效利用,采用热化学方法在下吸式固定床气化炉中生产了低热值秸秆燃气,对该燃气进行脱硫、脱氧、焦油催化分解、纯化、配氢等优化实验,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催化实验,在235℃和5 MPa条件下进行了催化剂种类及粒度对甲醇合成的影响实验.实验结果表明:合成甲醇的适宜催化剂型号为C301,最优化颗粒粒度为0.833 mm×0.351 mm.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 renewable and potential resource.In order to research the conversion of cornstalk biomass(the agricultural residues) into the fuel methanol and the effective utilization of biomass energy,the low-heat-value cornstalk gas is produced by the means of the thermo-chemical method in the down-flow fixed bed gasifier.The cornstalk gas is purified and the technical procedures such as desulfurization,catalytic cracking of tar,deoxygenation,purification and hydrogenation are performed,and the corn...
