Conoco's gasification process uses a synthetic CO/sub 2/ acceptor consisting essentially of at least one calcium compound (either calcium oxide or calcium carbonate) supported in a refractory carrier matrix having the general formula Ca/sub 5/(SiO/sub 4/)/sub 2/CO/sub 3/. The synthetic acceptor is more effective than a natural calcium oxide acceptor during the gasification process because the thermally stable matrix causes the calcium compounds to remain in discrete particles that tend to reactivate with each passage through the process. This eliminates the need for large quantities of fresh makeup acceptor materials.
