Abstract
A series of mixed matrix membranes using a commercially available aromatic polyimide (Matrimid® 5218) with nanoparticles formed from carbon, a porous organic polymer and metal organic frameworks were prepared to investigate the effects of flue gas impurities on gas permeation. We show that common impurities found in power station flue gases (H2S, SO2, and NO) have significant effects upon the performance of these mixed matrix membranes. The effects of NO, SO2 and H2S on the zeolitic imidazolate framework ZIF-8 are all large and rapid and would render these membranes unsuitable for flue gas service that do not use flue gas desulfurisation. Similarly, H2S adsorbs irreversibly into membranes co..
