| 摘 要： | 采用单一流化床二步气化方法,在流化床中用纯水蒸汽做气化剂进行生物质与煤共气化制取氢气的工艺试验.研究了反应温度、生物质与煤的质量比值、水蒸气和生物质的质量比值m(S)/m(B)等参数对产氢量的影响,同时考察不同工作条件下的焦油质量浓度.通过对气体成分和产率的试验分析计算出氢气的实际产量和最大产量.试验结果表明,反应温度和水蒸气量是提高氢气实际产量以及潜在产量的重要参数.当反应温度区间在950～1 000 ℃,m(S)/m(B)为0.9,生物质与煤的质量比值为4/1时,每千克无灰干基生物质和煤的实际产氢量为68.25 g,潜在产氢量最大值可达138.01 g.

| Abstract: | An experiment of hydrogen production from co-gasification of biomass and coal was conducted in a fluidized bed with steam as gasifying agent.Two-step gasification process in a fluidized bed was adopted in this experiment.Parametric experiments were performed to determine the effects of reactor temperature,biomass to coal and steam to biomass ratios,which had effect on hydrogen yield.At the same time tar content was investigated on different condition.Experimental measurements of gas composition and rate of ... |
