Abstract

Abstract:

　 Experiments for hydro gen production w ere carried out in subcritical and supercritical water in a batch - type reactor biomass set up by our selves. Glucose was used as a model compound, and CaO was used as CO₂remover in experiments. The effects of temperature , residence time and n (Ca) /n(C) on glucose reactions with and without CaO were examined by comparison and the optimal process for hydrogen production from biomass was also suggested. Under the condition of 480 ～530 ℃, above critical pressure , 2. 5%～ 5. 0 %mass fraction of glucose , 3～ 5 min resident time , n(Ca)/n(C) of 0. 45 ～ 0. 52 , the mass fraction of hydro gen is up to 67. 5 %.

Key words: Supercritical water, , Biomass, , Glucose, , CaO, , Hydrogen

摘要： 　利用自建的一套间歇式超临界生物质气化实验装置, 在水的近临界态和超临界态, 以葡萄糖为生物质模型化合物, 以制取氢气为目的进行实验研究。选用氧化钙为二氧化碳脱除剂, 对比在添加氧化钙前后, 反应温度、停留时间和n(Ca)/n(C)等因素对实验效果的影响。得出了新的超临界生物质气化制氢最佳工艺条件:温度在480 ～ 530 ℃, 压力在临界压力以上, 葡萄糖质量分数在2. 5%～ 5. 0%, 反应停留时间在3 ～ 5 min, n(Ca)/n(C)在0. 45～ 0. 52, H2 质量分数可以达到67. 5 %.
