20 Claims

1. A dehydrogenation catalyst composition comprising

Ga, present in the composition in an amount within a range of 2 wt. % to 20 wt. %, calculated as elemental metal on a calcined basis;

Ce, present in the composition in an amount within a range of 0.5 wt. % to 10 wt. %, calculated as elemental metal on a calcined basis;

Pt, present in the composition in an amount within a range of 1 ppm to 500 ppm, calculated as elemental metal on a calcined basis;

a promoter M2 selected from the alkali metals, the alkaline earth metals, and any mixture thereof, present in the composition in an amount of up to 7.5 wt. %, calculated as elemental metal on a calcined basis; and

a silica-alumina support S1, present in the composition in an amount within a range of 50 wt. % to 97.5 wt. % of the composition, calculated as oxide on a calcined basis, silica being present in S1 in an amount within a range of 5 wt. % to 30 wt. % of the mass of S1, calculated as SiO₂on a calcined basis,

wherein amounts of Ga, Ce, Pt, and promoter M2, are provided on the basis of the amount of the support S1 being 100 wt %.
