Abstract

The University of Illinois at Urbana-Champaign and URS Group, Inc. are developing, characterizing, and testing CO2 sorbents that can be used in a sorption-enhanced water-gas-shift (SEWGS) process for coal gasification plants. The SEWSG process combines the WGS and CO2 capture in one single process unit and would improve the plant's overall efficiency. In this study, thermodn. modeling studies were performed to identify the compns. of sorbents and operating conditions suitable for the SEWGS application. Various sorbents were prepd. using mech. alloying (MA), ultra-sonic spray pyrolysis (USP), and flame spray pyrolysis (FSP) approaches. Carbonation and recarbonation performances of the sorbents were evaluated over fifteen cycles using an atm. thermogravimetric analyzer (TGA). The sorbents exhibited higher capacities and better stabilities than several selected com. CaCO3 materials at temp. swings between 650Â°C and 900Â°C. Doping of the sorbents with magnesium, aluminum and zirconium further improved their stability. on SciFinder(R)]
