URS and the University of Illinois at Urbana-Champaign are investigating a dry sorbent process configured to combine the water-gas-shift (WGS) reaction with carbon dioxide (CO2) removal for coal gasification systems. A combination of process simulation modeling and sorbent molecular and thermodynamic analyses will be performed to predict optimal sorbent properties and identify optimal operating temperature and pressure ranges required to maximize the energy efficiency of the combined WGS and CO2 capture processes.

The goal of the project is to develop high performance sorbents that are capable of achieving 90 percent (%) CO2 removal, have high loading capacities, and operate at the high temperatures and pressures typically encountered upstream of a WGS reactor. If successful, the sorbents developed in this program will augment or replace the carbon monoxide (CO) conversion catalysts currently used in WGS reactors and improve overall WGS thermal efficiency. The process also enables CO2 capture and regeneration at high temperature and pressure, thus minimizing energy efficiency impacts on the treated integrated gasification combined cycle (IGCC) plant. Program objectives include identification of optimal sorbents and operating conditions for CO2 removal and regeneration and CO conversion in simulated syngas.
