An improved dehydrogenation catalyst bed system for olefin production
utilizing classical processing techniques is disclosed. The catalyst bed
system comprises a dehydrogenation catalyst comprising an active
component selected from an oxide of a metal of Group 4 or Group 5 or
Group 6 and combinations thereof and a support selected from aluminum
oxide, aluminas, alumina monohydrate, alumina trihydrate, alumina-silica,
transition aluminas, alpha-alumina, silica, silicate, aluminates,
calcined hydrotalcites, zeolites and combinations thereof mixed with a
first inert material selected from any material that is catalytically
inactive when subjected to reaction conditions that can effect
dehydrogenation of olefins and that has a high density and high heat
capacity and that is not capable of producing heat during any stage of
the dehydrogenation process, and the dehydrogenation catalyst plus the
first inert material then being physically mixed with a secondary
component comprising a heat-generating inert material and a carrier
capable of supporting the heat-generating inert material, wherein the
secondary component is catalytically inert with respect to
dehydrogenation reactions or to cracking or to coking and generates heat
after being exposed to reducing and/or to oxidizing reaction conditions.
