SELECTIVELY CALCINED DEHYDROGENATION CATALYST.

摘要

A catalyst found to be particularly effective in the dehydrogenation of ethylbenzene, diethylbenzene, and ethyltoluene, to olefinic compounds or vinyl aromatics where the catalyst includes iron oxide, at least 20% by weight alkali water gas promoter and at least 1.3% by weight chromium oxide where the catalyst is formed into pellets of selected configuration which are calcined at 900F to 1110F for 15 minutes to 8 hours.
