Claim 11:
12. A process for upgrading natural gas liquid (NGL) components into one or more higher molecular weight hydrocarbons, comprising:
providing a hydrocarbon gas comprising at least 30 mol % methane, at least 2 mol % ethane, and at least 2 mol % propane;
catalytically dehydrogenating, in the presence of the methane, at least a portion of the ethane and propane in the hydrocarbon gas to provide a dehydrogenation effluent comprising the methane, hydrogen, ethylene, propylene and one or more unconverted C2+ alkanes comprising ethane and/or propane;
catalytically 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.
