1. A process for preparing C2 to C3 hydrocarbons comprising:
introducing a feed stream comprising hydrogen gas and a carbon-containing gas selected from the group consisting of carbon monoxide, carbon dioxide, and mixtures thereof into a reaction zone of a reactor; and
converting the feed stream into a product stream comprising C2 to C3 hydrocarbons in the reaction zone in the presence of a hybrid catalyst, the hybrid catalyst comprising:
a mixed metal oxide catalyst component; and
a microporous catalyst component comprising 8-MR pore openings having a size less than or equal to 5.1 Å and a cage defining ring size less than or equal to 7.45 Å, wherein:
a C2/C3 carbon molar ratio of the product stream is greater than or equal to 0.7.
