First claim

Opening claim text (preview).

1 . A hybrid catalyst comprising: a metal oxide catalyst component comprising chromium, zinc, and at least one additional metal selected from the group consisting of iron and manganese; and a microporous catalyst component that is a molecular sieve having 8-MR pore openings, wherein the at least one additional metal is present in an amount from 5.0 at % to 20.0 at %. 2 . The hybrid catalyst of claim 1 , wherein the at least one additional metal is iron. 3 . The hybrid catalyst of claim 1 , wherein the at least one additional metal is manganese. 4 . The hybrid catalyst of claim 1 , wherein the microporous catalyst component is SAPO-34. 5 . The hybrid catalyst of claim 1 , wherein a ratio of chromium to zinc is from 0.35 to 0.45. 6 . The hybrid catalyst of claim 1 , wherein a ratio of chromium to zinc is about 0.40. 7 . The hybrid catalyst of claim 1 , wherein the metal oxide catalyst component is calcined at a temperature less than 600° C. 8 . The hybrid catalyst of claim 7 , wherein the metal oxide catalyst component is calcined at a temperature less than 500° C. 9 . The hybrid catalyst of claim 7 , wherein the metal oxide catalyst component is calcined at temperatures from 300° C. to less than 600° C. 10 . The hybrid catalyst of claim 1 , wherein the at least one additional metal is present in an amount from 5.0 at % to 17.5 at %. 11 . The hybrid catalyst of claim 1 , wherein the at least one additional metal is present in an amount from 7.5 at % to 17.5 at %. 12 . A process for preparing C 2 and C 3 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 C 2 and C 3 olefins in the reaction zone in the presence of the hybrid catalyst of claim 1 . 13 . The hybrid catalyst of claim 2 , wherein a ratio of chromium to zinc is from 0.35 to 0.45. 14 . The hybrid catalyst of claim 3 , wherein a ratio of chromium to zinc is from 0.35 to 0.45. 15 . The hybrid catalyst of claim 2 , wherein a ratio of chromium to zinc is from 0.35 to 0.45. 16 . The hybrid catalyst of claim 3 , wherein a ratio of chromium to zinc is from 0.35 to 0.45. 17 . The hybrid catalyst of claim 2 , wherein the metal oxide catalyst component is calcined at a temperature less than 600° C. 18 . The hybrid catalyst of claim 3 , wherein the metal oxide catalyst component is calcined at a temperature less than 600° C. 19 . The hybrid catalyst of claim 2 , wherein the at least one additional metal is present in an amount from 5.0 at % to 17.5 at %. 20 . The hybrid catalyst of claim 3 , wherein the at least one additional metal is present in an amount from 5.0 at % to 17.5 at %.
