摘　　要：以麦秸为对象,采用管式气化炉进行生物质蒸汽气化制取富氢气体实验研究。在非催化气化实验基础上,选取NiO、纯Fe粉以及橄榄石(FeMg)_2SiO_4这3类催化荆来提高氢含量。实验结果表明,气化反应温度在700～950℃范围内,氢体积浓度达到45%以上,添加Fe时达到了60%以上。非催化时,氢产率达到60g/(kg麦秸);添加催化剂时,Fe粉催化效果最好,最大产氢率达到119g/(kg麦秸);NiO次之,相比非催化时可提高40%;而橄榄石催化作用明显低于前两者。另外随着气化温度提高,3种催化剂的催化作用均增强。The experiments of biomass steam gasification to produce hydrogen-rich gas were carried out in a tubing gasifier. Based on non-catalytic gasification, three kinds of catalysts, such as NiO, Fe and Olivine, were adopted to catalytic gasification for hydrogen-rich gas. The experiment results showed that the hydrogen concentration can reach more than 45% （vol.） while gasification temperature is in the range of 700℃ to 950℃, the hydrogen can reach more than 60% （vol.） while the Fe is used as catalyst. In addition, the 60g/（kg biomass） hydrogen yield can be obtained under noncatalytic gasification. The Fe is shown the best catalytic effect, and the highest hydrogen yield is 119 g/（kg wheat straw）. The NiO also possesses better catalytic effect, and the hydrogen yield can increase 40 percent compared with non-catalytic gasification. But the catalytic effect of the olivine is worse than the formers. The results also showed that the effect of the three kinds of catalysts can be enhanced with raising the gasification temperature.
