Patent ID: 8123827

Claim:
A process of making a syngas-derived product from a carbonaceous feedstock, the process comprising the steps of: (a) providing a carbonaceous feedstock; (b)(i) reacting the carbonaceous feedstock in a gasification reactor in the presence of steam and a gasification catalyst under suitable temperature and pressure to form a raw product gas stream comprising a plurality of gases comprising methane, hydrogen, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and steam; (b)(ii) removing steam and ammonia from and sweetening the raw product gas stream to form a sweetened gas stream; (b)(iii) separating carbon monoxide and hydrogen from the sweetened gas stream to provide a synthesis gas stream and a methane gas stream, wherein the synthesis gas stream comprises hydrogen and carbon monoxide; (c) conveying the synthesis gas stream to a syngas reaction zone; (d) reacting the synthesis gas stream in the syngas reaction zone to form the syngas-derived product and heat energy; (e) recovering the syngas-derived product; and (f) recovering the heat energy formed from the reaction of the synthesis gas stream.
