Research Progress in Fillersof Mixed Matrix Membrane Based on CO2 Separation

Efficient, green and low-energy CO₂ capture technology is the key to solving the problem of energy gas purification and greenhouse gas emission reduction. Membrane separation technology has potential prospects for development because of its high efficiency, energy saving, low carbon and other characteristics in the field of CO₂ capture. At present, the study of CO₂ separation membrane mainly focuses on the filler in mixed matrix membrane, and the "trade-off" effect between membrane permeability and selectivity is controlled by adjusting the filler. Mixed matrix membrane separation technology show a good application prospects in the field of gas separation. For the mixed matrix membrane, the filler is usually a key factor affecting its separation performance. In recent years, researchers have found that the filler is usually a key factor affecting separation performance of the mixed matrix membrane and the use of different fillers can improve the gas separation performance of the mixed matrix membrane. This paper summarizes the filler that has been developed at present. So as to provide a reference for the design and development of new mixed matrix membrane for CO₂ separation.
