초록 ▼

A gas conversion process including catalytic hydrocarbon synthesis from a synthesis gas comprising a mixture of H.sub.2 and CO, produces hydrogen from the synthesis gas and upgrades synthesized hydrocarbons by one or more hydroconversion operations which utilize this hydrogen. The hydroconversion also produces a hydrogen rich tail gas which is used in the process for at least one of (i) hydrocarbon synthesis catalyst rejuvenation, (ii) the hydrocarbon synthesis, and (iii) hydrogen production. In one embodiment the tail gas is used to hydrodesulfurize sulfur-containing hydrocarbon liquids recovered from the natural gas used to form the synthesis gas. The hydrogen production is accomplished by physical separation, such as PSA, with or without chemical means such as a water gas shift reaction.

대표청구항 ▼

[ What is claimed is:] [1.] A gas conversion process comprising:(a) synthesizing hydrocarbons by reacting a synthesis gas comprising a mixture of H.sub.2 and CO in the presence of a Fischer-Tropsch hydrocarbon synthesis catalyst, at reaction conditions effective to react said H.sub.2 and CO to form hydrocarbons,(b) upgrading at least a portion of said synthesized hydrocarbons by reacting them with hydrogen, or a hydrogen containing gas, in the presence of a hydroconversion catalyst, to produce upgraded hydrocarbons and a hydrogen rich tail gas, and(c) using said hydrogen rich tail gas for at least one of (i) said hydrocarbon synthesis, (ii) hydrogen production, (iii) rejuvenation of said hydrocarbon synthesis catalyst, and (iv) hydrodesulfurization of sulfur-containing hydrocarbons.
