Abstract
An integrated process for producing a hydrocarbon stream including C normal and iso-paraffins is disclosed. The process involves isolating a non-sulfur containing methane stream and a sulfur-containing C + stream from a natural gas source. The methane stream is converted to syngas and further reacted to form a higher molecular weight hydrocarbon product stream. The C hydrocarbons in that product stream are hydroprocessed along with at least a portion of the C + stream from the natural gas source. The presence of sulfur in the C + stream minimizes the hydrogenolysis that would otherwise occur if the C hydrocarbons were hydroprocessed without added sulfur-containing compounds or other hydrocracking suppressants. The result is an improved yield of C hydrocarbons relative to when the hydroprocessing step does not include hydrocracking suppressants.
