Catalyst systems and methods for mixed cracking of hydrocarbons and selective hydrogen combustion are disclosed. The catalyst system comprises at least one solid acid component and at least one metal base component, the metal base component comprising (a) oxygen and / or sulfur and (b) a metal combination selected from the group consisting of: i ) At least one metal of Group 3 of the Periodic Table of Elements and at least one metal of Group 4-15; ii) at least one metal of Group 5-15 of the Periodic Table of Elements, and Period of Elements At least one metal selected from at least one of groups 1, 2 and 4 of the table; iii) at least one metal of groups 1 and 2 of the periodic table of elements, at least one metal of group 3 And at least one metal of Group 4-15; and iv) two or more metals of Group 4-15 of the Periodic Table of Elements, wherein at least one of oxygen and sulfur is intermetallic Chemically bond with Optionally, (3) at least one of at least one carrier, at least one filler, and at least one binder. In this method, the hydrogen yield is lower than the hydrogen yield when only the hydrocarbon and the solid acid component are contacted. Furthermore, NO x emissions from the regeneration cycle of the catalyst system is reduced. |
