Study of calcium-based waste on adsorption enhanced biomass gasification for hydrogen production

Funds: The project was supported by the National Key Research and Development Program of China (2019YFB1503900)
  • 摘要:

    为了提高生物质气化制氢效率,综合利用工业固废资源,利用钙基废弃物——电石渣作为CO2吸附剂,在两段式固定床上探究了钙基废弃物的添加量、反应温度对生物质气化制氢特性的影响,着重研究了吸附剂在实际应用中的循环吸附性能,并以此探讨了电石渣对生物质吸附增强气化的影响机制。结果表明,随着电石渣添加量的逐渐增加,H2产量和含量都呈现出增加的趋势。而随着温度的升高,H2产量和含量先增加后减小。当CaO/C物质的量比为1,重整段温度为700 ℃时,气体产物中的H2产量和含量为154.34 mL/g(生物质)和26.76%,获得最大值。当电石渣循环次数小于5时,H2的含量和产量相较于初次反应都有所增加。
