  • Natural Gas Liquids Upgrading Process: Two-Step Catalytic Process For Alkane Dehydrogenation And Oligomerization
    Publication number: 20230227735
    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.

  • Increased oligomer selectivity from olefin oligomerization by incorporation of boron
    Patent number: 11358912
    Abstract: A novel catalyst composition and its use in the oligomerization reactions of light alkenes to higher molecular weight hydrocarbons. The catalyst comprises boron added to an Al-containing or Ga-containing or Fe-containing support. The catalyst composition is an active and selective catalyst for the catalytic oligomerization reactions of light alkenes to higher molecular weight hydrocarbons.
