A novel catalytic composition comprises a combination of a Group VIII noble metal component, a Group IA or IIA metal component, and a component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium, or mixtures thereof, with a theta-alumina support having a low surface area of 120 m<2>/g or less, and an ABD of 0.5 g/cm<3> or more. The novel catalytic composite has particular utility as a hydrocarbon dehydrogenation catalyst. |
