利用间隙式釜式反应器
在反应器内流体温度为450 ℃、初压为4 MPa(终压为22~27 MPa)、保温时间为20 min、NaOH作为催化剂的条件下
分别对生物质模型化合物羧甲基纤维素钠(CMC)与煤以及原生生物质玉米芯与煤的超临界水气化制氢进行实验研究.结果表明:CMC/煤共超临界水气化制氢过程中
共气化的产氢率和气化率均高于同样情况下CMC、煤单独气化的加权平均值
玉米芯/煤共气化也出现类似结果
这说明CMC/煤、玉米芯/煤共超临界水气化制氢均存在协同效应.初步分析了协同效应产生的机理.
Hydrogen production from carboxymethylcellulose(CMC)/coal and corncob/coal gasified in supercritical water(SCW)is investigated experimentally by batch reactor with fluid temperature of 450 ℃
original pressure 4 MPa(final pressure 22-27 MPa)
a residence time 20 min and NaOH as catalyst. The results show that hydrogen yield and gas efficiency for CMC/coal co-gasification are higher than the average value for CMC and coal gasification separately under the same conditions. The similar results are also found for corncob/coal
which indicates the synergistic effects for CMC/coal and corncob/coal co-gasification in SCW.
