Title: A calcium oxide sorbent process for bulk separation of carbon dioxide

Conference ·
OSTI ID:10107704

The overall project is divided into two phases. Phase I, now complete, investigated the technical feasibility of a regenerable calcium sorbent-based process for the high-temperature, high-pressure (HTHP) separation of CO{sub 2} from coal-derived gas. A high-pressure electrobalance reactor and microgram quantities of sorbent were used in this phase of the study. Favorable results led to continuation of the project into Phase II where a laboratory-scale fixed-bed reactor involving gram quantities of sorbent and with capability for product gas analysis is being used. The possibility of the simultaneous occurrence of the water-gas shift reaction and CO{sub 2} separation is of particular interest in Phase II. Simultaneous reactions create the possibility of a direct, one-step process for producing hydrogen from coal-derived gas.
