Abstract: A hybrid catalyst including a metal oxide catalyst component comprising chromium, zinc, and at least one additional metal selected from the group consisting of aluminum and gallium, and a microporous catalyst component that is a molecular sieve having 8-MR pore openings. The metal oxide catalyst component includes anatomic ratio of chromium:zinc (Cr:Zn) from 0.35 to 1.00, and the at least one additional metal is present in an amount from 25.0 at % to 40.0 at %. A process for preparing C2 and C3 olefins comprising: a) 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 b) converting the feed stream into a product stream comprising C2 and C3 olefins in the reaction zone in the presence of said hybrid catalyst.
