Research on the Performance of Solid Acid Catalysts for Catalyzing the Regeneration of CO2-Rich MEA Solution
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.
