摘要
利用ASPEN PLUS软件建立了生物质水蒸气气化制氢模型,对各种影响因素进行了深入分析。结果表明:随着碳转化率的增加,H2浓度略有降低,H2产量大幅增加,在碳转化率为1时达到最大值142.54 g/kg;随着水蒸气/生物质质量比的增加,H2浓度和产量大幅增加,而后趋于稳定,水蒸气/生物质质量比取2比较适宜。适当的升温和低压对制备H2有利,在加压条件下,H2浓度与产量达到最大值的温度升高。
In order to study biomass steam gasification for hydrogen production furtherly, a gasification model was built using ASPEN PLUS, and the effects of various factors on gasification characteristics were analyzed. The results showed that, as carbon conversion rate increased, the hydro- gen concentration decreased slightly, the hydrogen production increased greatly and it got a maxi- mum value of 142.54 g/kg at carbon conversion rate of 1. As mass ratio of steam to biomass in- creased, the concentration and production of hydrogen firstly increased greatly then got steady, and the suitable value of mass ratio of steam to biomass is 2. Appropriate temperature rising and low pressure is beneficial for hydrogen production, and under pressurized conditions, the temperature increased when the concentration and production of hydrogen reached maximum
