A broad range of mesoporous silica - Amine composite powders were prepared, and readily shaped into robust forms, as are preferred for industrial applications, in accord with recently patented bindcrless shaping technologies. such materials are of key interest to facilitate CO2 capture, such as to help mitigate global warming. shaping of the powders was otherwise found to be problematic due to product extrusion and/or texture. select shaped products prepared in accord with the patent technologies were then subjected to CO2 partial pressure swing adsorption (ppsa) processing. these products were found to exhibit up to wt % and -11 wt % CO2 working capacity, as estimated for the post combustion capture (PCC) of CO2 from simulated flue gases via pressure swing adsorption (psa) and thermal swing adsorption (TSA) processing respectively. the patent technologies were thus found to provide a promising opportunity to facilitate the preparation of robust sorbent options for CO2 capture applications.
