1. A process for preparing C2 and C3 olefins 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 and C3 olefins in the reaction zone in the presence of a hybrid catalyst, wherein the hybrid catalyst comprises:
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 SAPO-34 microporous catalyst component, wherein
an atomic ratio of chromium:zinc (Cr:Zn) is 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 %.
