| 摘 要： | 搭建了一套连续式多碟太阳能聚热与生物质超临界水气化耦合制氢系统,以生物质模型化合物(乙二醇、丙三醇、葡萄糖)为原料在该装置上进行了气化制氢实验,研究了太阳能直接辐照度(DNI)、物料成分、物料浓度、停留时间对气化效果的影响。实验结果表明:太阳能直接辐照度对太阳能吸收器腔内及反应器壁温的影响较大,进而能影响气化效果,在实验流量、压力范围内当DNI为363～656W/m2时,反应器出口流体温度达520～676℃,可以满足生物质超临界水气化制氢的温度及能量需要。0.1mol/L葡萄糖气化H2体积分数均值超过50%,H2产量为27.2mol/kg,气化率达109.7%。低物料浓度和长停留时间有利于气化效果的提高。实验验证了利用可再生的太阳能聚焦供热耦合生物质超临界水气化制氢是可行的。
