Abstract: A process to catalytically transform natural gas liquid (NGL) into higher molecular weight hydrocarbons includes providing an NGL stream, catalytically dehydrogenating at least a portion of the NGL stream components to their corresponding alkene derivatives, catalytically oligomerizing at least a portion of the alkenes to higher molecular weight hydrocarbons and recovering the higher molecular weight hydrocarbons. The NGL stream can be extracted from a gas stream such as a gas stream coming from shale formations. The higher molecular weight hydrocarbons can be hydrocarbons that are liquid at ambient temperature and ambient pressure.

Abstract: Processes and systems for upgrading natural gas liquids. At least a portion of the natural gas liquid components in a shale gas stream can be dehydrogenated to their corresponding olefin derivatives prior to separating any methane from the liquids. Further processing subsequent to dehydrogenation could include various separations, oligomerizing olefins produced in the dehydrogenation step, recovering desired products, etc. The order of the processing steps subsequent to dehydrogenation could be adjusted in various cases.
