PLATINUM AND TIN-CONTAINING CATALYST AND USE THEREOF IN ALKANE DEHYDROGENATION

摘要

In a process for preparing a dehydrogenation catalyst of the type in which a support comprising zinc aluminate is impregnated with at least one of platinum and tin from an impregnation solution, the improvement comprises simultaneously impregnating the support with the platinum and the tin by contacting the support with an impregnation solution which comprises, in solution, a tin compound, a platinum compound, and a carboxylic acid. The thus prepared catalyst can be employed in the dehydrogenation of at least one alkane containing ~-8 carbon atoms per molecule in the presence of steam.
