Increase propane dehydrogenation activity of a partially deactivated dehydrogenation catalyst by heating the partially deactivated catalyst to a temperature of at least 660&#xb0; C., conditioning the heated catalyst in an oxygen-containing atmosphere and, optionally, stripping molecular oxygen from the conditioned catalyst.

Reactivating propane dehydrogenation catalyst

A process for the dehydrogenation of a paraffinic hydrocarbon compound, such as an alkane or alkylaromatic hydrocarbon compound to produce an unsaturated hydrocarbon compound, such as an olefin or vinyl aromatic compound or mixture thereof, in which a dehydrogenation catalyst contacts gaseous reactant hydrocarbons in a reactor at dehydrogenation conditions.

Process for the preparation of hydrogenated hydrocarbon compounds

A supported catalyst and process for dehydrogenating a hydrocarbon, the catalyst comprising a first component selected from the group consisting of tin, germanium, lead, indium, gallium, thallium, and compounds thereof; a second component selected from the group consisting of metals of Group 8 of the Periodic Table of the Elements and compounds thereof, and a support comprising alumina in the gamma crystalline form. The catalysts are especially active and efficient when employed in concurrent flow in a dehydrogenation reactor having an average contact time between the hydrocarbon and catalyst of from 0.5 to 10 seconds.
