process for the activation of catalytic precursors for dehydrogenation of paraffins c2 - c5 and catalytic composition activated by the process

摘要

the process for the activation of a catalytic composition for deidrogenare paraffins containing gallium, alumina, or silica and / or one or more of alkali metals or alkaline earth.includes a thermal activation in air.following a post activation through the following stages: - oxidation with air and / or oxygen or a mixture containing oxygen and inert gas; washing with an inert gas; - reduction with hydrogen ora mixture of hydrogen and inert gas or a reducing agent.the catalytic composition activated by said procedure, contains gallium, alumina, silica, and possibly one or more of alkali metals or alkaline earth.the alumina is in phase (symbols) or mixture of phases (symbols).
