Gas conversion using hydrogen from synthesis gas and hydroconversion tail gas

A gas conversion process including catalytic hydrocarbon synthesis from a synthesis gas comprising a mixture of H2 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 pr...

More Information
Summary:A gas conversion process including catalytic hydrocarbon synthesis from a synthesis gas comprising a mixture of H2 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.
