A novel catalyst composite is disclosed. Also disclosed is a use for the novel composite. The catalyst composite comprises 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, all on an alumina support comprising essentially theta-alumina, having a surface area from about 50 to about 120 m2/g, an apparent bulk density of at 0.5 g/cm3 and a mole ratio of the Group VIII noble metal component to the component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium or mixtures thereof in the range from about 1.5 to about 1.7.
A catalytic composite comprising a first component selected from the group consisting of Group VIII noble metal components and mixtures thereof, a second component in an amount of from 0.9 to 1.1 weight percent, based on the total composite weight, selected from the group consisting of alkali metal components, alkaline earth metal components, and mixtures thereof, and a third component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium, and mixtures thereof, all supported on an alumina support comprising essentially theta-alumina, said support having a surface area of from about 50 to about 120 m2/g and an apparent bulk density of at least 0.5 g/cm3, and wherein the mole ratio of the first component to the third component is in the range of from about 1.5 to about 1.7.
A catalytic composite comprising platinum, potassium in an amount of from 0.9 to 1.1 weight percent, based on the total composite weight, and another component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium, and mixtures thereof, all supported on an alumina support, said alumina comprises essentially of theta-alumina, which has a surface area of from about 50 to about 120 m2/g, an apparent bulk density of greater than about 0.6 g/cm3, and a mole ratio of platinum to said another component of from about 1.5 to about 1.7.
