摘要:在间歇式反应器中研究TiO(OH)2、MCM-41、SAPO-34、Mont等4种单一固体酸催化剂在MEA富液再生过程中的催化效果。结果表明,4种固体酸催化剂可以降低再生能耗12.78~23.22个百分点。通过离子交换利用Fe、Zr和Ce等3种金属对蒙脱土(Mont)进行修饰,结果表明,经过金属修饰后的Mont催化性能有大幅提升,3种M-Mont的催化性能均优于单一的Mont,其中Zr-Mont表现最佳,解吸能耗可降低27.46个百分点。

Abstract:The catalytic effects of four single solid acid catalysts,TiO(OH)2,MCM-41,SAPO-34 and Mont on the process of MEA(monoethanolamine)flooded regeneration were studied in batch reactors.The results show that the four solid acid catalysts can reduce the regeneration energy consumption by 12.78 to 23.22 percentage points. Mont was modified by three metals,Fe,Zr,and Ce through ion exchange.The results show that the catalytic performance of the Mont after modification is largely improved,and the catalytic performance of the three M-Monts is better than that of a single Mont,among which Zr-Mont shows the best performance,and its desorption energy consumption can be reduced by 27.46 percentage points.
