Abstract:
A catalyst composition for the production of synthesis gas from light hydrocarbons, the catalyst composition comprising a crystalline metal oxide component having a chemical composition on an anhydrous basis expressed by an empirical formula of:Av(Bt+)wNixD(Guâˆ’)yOz where A is an alkali metal selected from the group consisting of Li+, Na+, K+, Rb+, Cs+, and mixtures thereof, â€œvâ€  is the mole ratio of A to D and varies from 0 to about 2, B is a basic metal, â€œwâ€  is the mole ratio of B to D and varies from about 1 to about 3, â€œtâ€  is the weighted average valence of B and varies from 2 to about 3, â€œxâ€  is the mole ratio of Ni to D and varies from 0 to about 0.5, D is a framework component selected from the group consisting of P+5, V+5, and mixtures thereof, and G is an anionic species selected from the group consisting of OHâˆ’, Clâˆ’, Fâˆ’, CO32âˆ’, and mixtures thereof, â€œuâ€  is the average valence of G and varies from 1 to about 2, â€œyâ€  is the mole ratio of G to D and varies from 0 to about 2, â€œzâ€  is the mole ratio of O to D and has a value determined by the equation:z=Â½(v+tÂ·w+2Â·x+5âˆ’uÂ·y), and when B is Ca, â€œvâ€  is not 0, and when â€œxâ€  is 0, the catalyst composition further comprises a nickel component dispersed on the crystalline metal oxide component.
