A gas conversion process comprising synthesis gas production, hydrocarbon synthesis and hydrogen production from the synthesis gas, also includes hydrodesulfurizing sulfur-containing hydrocarbon liquids separated from a mixture of natural gas and the liquids produced from a gas well. Hydrogen produced from the synthesis gas is used for the hydrodesulfurization, to remove at least a portion of the sulfur as H2S and form desulfurized hydrocarbon liquid. The hydrogen is produced from the synthesis gas by one or more of (i) physical separation means such as pressure swing adsorption and (ii) chemical means such as a water gas shift reactor. The synthesized hydrocarbons are upgraded by hydroconversion. A portion of the hydrogen produced from the synthesis gas may also be used for at least one of (i) hydrocarbon synthesis catalyst rejuvenation and the hydroconversion.
