摘要
由生物质废弃物催化裂解制取氢气是一种可再生的制氢方法，本研究采用2段加热管式反应器，前段装生物质，后段装催化剂，用以研究生物质催化裂解制取氢气的特性，并提出潜在氢产率的概念对生物质制氢的经济技术可行性进行深入的分析。测试的3种生物质废弃物为：松木粉、木质素和纤维素，测试温度为600～700℃。实验结果表明，加入催化剂后3种物料的产氢率从5．48～15．06g／kg增加到12．94～37．73g／kg；催化剂对潜在产氢率的影响较小，加入催化剂前后的变化范围为：36、25～98、86g／kg到37．40～116．98g／kg。生物质废弃物催化裂解产氢率与相同温度下空气-水蒸气气化的氢产率相当，实验结果证明，生物质废弃物催化裂解是一种有效的制氢方法。
Renewable hydrogen can be produced from biomass catalytic pyrolysis. In the present study, two tubular furnaces were connected in series, one filled with biomass samples, the other filled with catalysts, to explore the characteristics of hydrogen yield from biomass catalytic pyrolysis. The idea of hydrogen yield potential （HYP） was put forward in order to have a deep analysis on the technical-economic evaluation of hydrogen pro- duction from biomass. Three samples： wood powder, lignin and cellulose were used as the test materials and the temperature range was between 600～700℃. The test results indicated that the hydrogen yield was improved from 5.48～15.06 g/kg biomass to 12.94～37.73 g/kg biomass in the presence of catalysts. The catalysts had a relative small effect on HYP and its yield was increased from 36.25～98.86 g/kg to 37.40～116.98 g/kg. Hydrogen yield from biomass catalytic pyrolysis was comparable with hydrogen yield from biomass air-steam gasification at the same temperature, which proves that biomass catalytic pyrolysis is an effective way for hydrogen production.
