摘要
文章探讨了城市生活垃圾催化热解要素对氢气制取过程的影响.研究催化剂（纳米NiO/γ-Al2O3、纳米NiO/赤泥）、温度、进料速度三因素对城市生活垃圾催化热解产气、产氢的影响规律.实验结果表明,在热解温度750～900℃范围内,两种催化剂分别作用下的产气量和氢气含量均随着温度的升高明显提升,并在900℃时达到最大.相同实验条件下,螺旋进料器进料速度在30转/分条件时（25转/分～40转/分范围内）的制氢效果最佳.相对于无催化剂条件下的热解过程,生活垃圾催化热解的产气量和氢气含量均较之有明显提升,纳米NiO/γ-Al2O3催化效果优于纳米NiO/赤泥.
The influencing factors on hydrogen production from municipal solid waste（MSW）during catalytic pyrolysis were discussed in this paper. The study for the influence rule of catalyzers （Nano NiO/γ-Al2O3, Nano NiO/red mud）, furnace temperature and feed speed of spiral feeder on hydrogen production from MSW was carried out. The result showed that the gas production and the hydrogen rate both increased while the temperature gone up （in the range of 750-900 ℃）. In addition, when the feed speed of spiral feeder varied from 25-40 r/min, the hydrogen production reached the best at the speed of 30 r/min. Compared with the non-use of catalyst pyrolysis process, the gas production and the hydrogen rate both made a remarkable enhancement in the catalytic pyrolysis process of MSW. Nano NiO/γ-Al2O3 was better than nano NiO/red mud.
