Claim 0:
1. A process for upgrading natural gas liquids (NGL) into higher molecular weight hydrocarbons, comprising:
providing a hydrocarbon gas comprising 30 mol % to about 95 mol % of methane, and about 5 mol % to about 40 mol % C2+ alkanes;
dehydrogenating, in the presence of the methane, at least a portion of the C2+ alkanes in the hydrocarbon gas to provide a dehydrogenation effluent comprising the methane, hydrogen, ethylene, propylene and one or more unconverted C2+ alkanes;
oligomerizing, in the presence of the methane, at least a portion of the ethylene and propylene in the dehydrogenation effluent to provide one or more C4 to C26 hydrocarbons; and then
separating the methane from the one or more C4 to C26 hydrocarbons.
