摘要
采用等体积浸渍法在HZSM-5负载不同含量的Cu、Fe、Mo和Nb,在98℃油浴下研究金属改性HZSM-5对5 mol/L乙醇胺(Monoethanolamine,MEA)富液解吸CO_(2)的影响,并与空白对照实验进行对比。结果表明,0.6Nb-HZSM-5催化效果最佳,可将最大解吸速率提高74.6%,解吸负载提高46.3%,相对能耗降至65.2%;0.6Nb-HZSM-5经4次使用后可将解吸负载提升40.0%,相对能耗降低30.5%,具有良好的稳定性,成型后催化效果优于HZSM-5。
The equal volume impregnation method was adopted to load different contents of Cu,Fe,Mo and Nb on HZSM-5.The effect of metal-modified HZSM-5 on the desorption of CO_(2)in 5 mol/L monoethanolamine(MEA)rich liquid was studied under an oil bath at 98℃,and it was compared with the blank control experiment.The results show that 0.6Nb-HZSM-5 has the best catalytic effect,which can increase the maximum desorption rate by 74.6%,increase the desorption load by 46.3%,and reduce the relative energy consumption to 65.2%;After four uses,0.6Nb-HZSM-5 can increase the desorption load by 40.0%and reduce the relative energy consumption by 30.5%.It has good stability and the catalytic effect after molding is better than that of HZSM-5.
