摘　　要：采用从牛粪堆肥中获取的Clostridium sp.Fanp2菌种作为产氢菌源,考察了联合预处理的玉米秸秆在序批式小型反应器及放大的5 L、30 L反应器的产氢能力,研究了玉米秸秆发酵序批式小型反应器和5 L、30 L放大反应器的产氢动力学,采用修正的Gompertz方程拟合产氢动力学实验数据,建立了各个反应器玉米秸秆发酵产氢动力学模型,确定了产氢动力学参数,并进行数理验证,关联度R2均大于0.99,动力学方程显著可靠.In this study, Clostridium sp. Fanp2, as bio-hydrogen production bacterial source, was achieved from cow dung compost. The capability of hydrogen production was investigated in small batch reactors, 5 L and 30 L reactors from pretreatment corn straw. Then, the kinetics of hydrogen production from corn straw was studied about small batch fermentation reactor and 5 L, 30 L reactors. The experimental data of kinetics of hydrogen production was in agreement with the modified Gompertz equation, then the kinetics model of corn straw＇ s hydrogen production in the batch reactor and 5 L, 30 L reactors were established and the kinetics of hydrogen production parameters was determined. And the kinetics model were analyzed with mathematical sta- tistics method. The calculation results show that the association degree greater than 0.99, respectively. So the kinetic equation was reliable.
