Process for activating catalyst precursors for the dehydrogenation of C2-C5 paraffins, and a catalytic composition activated by the process. |
摘要 |
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. <IMAGE> |
