Process for conversion of natural gas and associated light hydrocarbons to salable products

摘要

Salable hydrocarbon products prepared by reacting a light hydrocarbon gaseous stream with a gaseous oxidant to produce carbon oxides and hydrogen, which is contacted in a hydrocarbon synthesis zone to produce a product stream comprising salable hydrocarbon products. That product stream is separated into a gaseous fraction and at least one fraction of salable hydrocarbon products. The light hydrocarbon gaseous stream is formed by separating a light hydrocarbon gaseous feed comprising alkanes into a lighter fraction and a heavier fraction and contacting that heavier fraction in a disproportionation zone to convert a significant portion of the alkanes in the heavier fraction by disproportionation into both higher and lower alkanes, then at least part of the lighter fraction and the lower alkanes form the light hydrocarbon gaseous stream.
