Processes for improving the activity of hybrid catalysts
A process for converting a feed stream to C.sub.2 to C.sub.5 hydrocarbons includes introducing a feed stream of hydrogen and at least one carbon-containing component selected from CO, CO.sub.2, 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.
