摘　　要：以水蒸气为气化介质,在固定床实验台上进行生物质/甘油共气化制氢实验研究。实验考察给水速度、Ca O、压力、催化剂对制氢结果的影响,结果表明:由于Ca O的存在,给水速度对氢气浓度的影响呈曲线变化。提高Ca O的含量能明显促进氢气的产生;压力的升高促进共气化向制氢方向的进行,这与压力对生物质、甘油单独气化的影响截然相反;镍基催化剂的使用存在最佳值,过量催化剂会抑制制氢反应的进行。We experimentally studied the co-steam-gasification of biomass and glycerol for producing hydrogen in a fixed bed, and evaluated the effects of the amount of water fed, the addition of CaO, operating pressure, and the amount of catalyst used on the hydrogen yield. The results showed that the concentration of H2 with water fed shows a curve change due to the presence of CaO, but increasing the amount of CaO added can substantially enhance the yield. The experiment also finds that increasing the operating pressure favors the hydrogen production in this co-gasification, whereas increasing the operating pressure reversibly affects the production when biomass or glycerol is the only feeding material. In addition, we also find that the excessive use of the Ni-based catalyst prevents the yield, indicating that the amount of catalyst used needs to be well controlled.
