CASE 3510 PROCESS FOR ACTIVATING CATALYST PRECURSORS FOR THE DEHYDROGENATION OF C2-C5 PARAFFINS, AND A CATALYTIC COMPOSITION ACTIVATED BY THE PROCESS Abstract The process for activating a catalytic composition for paraffin dehydrogenation containing gallium, alumina, possibly silica and/or one or more alkaline or alkaline-earth metals, comprises thermal activation in air followed by post-activation effected by the following stages: - oxidation with air and/or oxygen or a mixture containing oxygen and inert gas; - purging with inert gas; - reduction with hydrogen or a mixture of hydrogen and an inert or reducing gas. The catalytic composition activated by said process contains gallium, alumina, silica and possibly one or more alkaline or alkaline-earth metals, the alumina being in .delta. or .theta. phase or in .delta. + .theta. or .delta. + .theta. + .alpha. phase mixture.
