Abstract

Separation of CO2 from various gaseous streams is becoming increasingly important in the field of energy production and sustainable use of fossil energy. A new kind of CO2 "molecular basket", which shows high CO2 capacity and superior CO2 selectivity, was developed. The effect of different types of PEI on the adsorption separation performance of the CO2 "molecular basket" adsorbents was presented. Highly effective CO2 "molecular basket" adsorbent could be prepared by using mesoporous molecular sieve MCM-41 and polyethylenimine with a linear structure. The adsorbent with linear PEI showed a higher CO2 adsorption capacity and a faster CO2 adsorption/desorption rate, than those for the "molecular basket" adsorbent with branched PEI. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
