  • Patent number: 10703689
    Abstract: A process for converting a feed stream to C2 to C5 hydrocarbons includes introducing a feed stream of hydrogen and at least one carbon-containing component selected from CO, CO2, and mixtures thereof into a reaction zone at an initial reactor pressure and an initial reactor temperature. The feed stream is contacted to a hybrid catalyst positioned in the reaction zone, and the hybrid catalyst includes a methanol synthesis component and a solid microporous acid material. The pressure within the reaction zone is increased during the contacting of the feed stream to the hybrid catalyst from the initial reactor pressure to a final reactor pressure. A temperature within the reaction zone at any time during the contacting of the feed stream to the hybrid catalyst is within ±20° C. of the initial reactor temperature.
