摘要： A process for the production of a synthesis gas, capable of being upgraded to a high BTU pipeline gas, by the partial oxidation and substantially complete gasification of a carbonaceous material under CO-promoting conditions wherein the carbonaceous material, oxygen, and recycled carbon dioxide from the process are introduced into a molten salt containing an alkali metal carbonate and a minor portion of an alkali metal sulfide, the system being operated at a selected temperature and pressure between 1400.degree. and 2000.degree. F and between 1 and 100 atmospheres. The molar ratio of carbon dioxide to oxygen employed is controlled at from about 0.6:1 to about 1.2:1 to control the CO production and also to maintain the molten salt at a desired operating temperature. Sulfur and ash introduced with the fuel are retained in the molten salt. The gaseous effluent, containing a molar ratio of carbon monoxide to carbon dioxide substantially greater than one, is reacted in a water gas shift reaction, followed by removal of the carbon dioxide present in the gaseous effluent from the shift reaction to produce the synthesis gas, capable of being reacted further under appropriate conditions to produce pipeline gas, methanol, ammonia, or gasoline. At least a portion of the removed carbon dioxide is recycled for admixture with the oxygen to form the feed gas to the molten salt containing the carbonaceous material.
