ABSTRACT OF THE DISCLOSURE A process for activating a catalytic composition including a porous inorganic oxide carrier, a platinum group component and a tin component, comprising: reacting the catalytic composition with an activating gas in- cluding oxygen at a temperature within the range from about 500°F. to about 1300°F. for at least about 0.5 hour. The activating gas preferably includes a halogenating component. The activating gas is preferably slightly moist and is preferably flowed through the catalytic composition. The catalytic composition may comprise a fresh catalytic composition, a regenerated catalytic composition, or a mixture thereof. A preferred activated catalytic composition comprises an alumina carrier, 0.01 to 3 weight percent platinum, 0.01 to 5 weight percent tin, 0.001 to 1 weight percent iridium and 0.01 to 3 weight percent halide. Also covers the resulting activated catalytic compositions.
