    摘要： The present invention provides processes for making synthesis gas and processes for making syngas-derived products. For example, one aspect of the present invention provides a process for making a synthesis gas stream comprising hydrogen and carbon monoxide, the process comprising (a) providing a carbonaceous feedstock; (b) 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 and carbon monoxide; (c) removing steam from and sweetening the raw product gas stream to form a sweetened gas stream; (d) separating and adding steam to the sweetened gas stream to form a first reformer input gas stream having a first steam/methane ratio; and a second reformer input stream having a second steam/methane ratio, in which the first steam/methane ratio is smaller than the second steam/methane ratio; (e) reforming the second reformer input stream to form a recycle gas stream comprising steam, carbon monoxide and hydrogen; (f) introducing the recycle gas stream to the gasification reactor; and (g) reforming the first reformer input stream to form the synthesis gas stream.
