Abstract

Heat is supplied to an endothermic catalytic reaction employing a fluidized or moving bed of catalyst by including in the catalyst a metal oxide which is reduced with evolution of heat under reaction conditions and using excess oxygen during regeneration to reoxidize reduced metal oxide. The process described is one of dehydrogenation and dehydrocyclization of non-aromatic hydrocarbons (see Group IV (b)) at a temperature of 800-1300 DEG F. employing a chromium oxide-alumina catalyst, the metal oxide added being cupric oxide in an amount of 5-25% by weight of the total catalyst. The catalyst may be promoted with an oxide of a rare earth, bismuth, boron or germanium with or without an alkali metal or a spinal such as cobalt chromite, copper chromite, zinc titanate or iron chromite.ALSO:In an endothermic process for the catalytic dehydrogenation or dehydrocyclization including reforming of hydrocarbon feedstocks containing non-aromatic hydrocarbons employing a fluidized or moving catalyst bed and a reaction temperature of 800-1300 DEG F., heat is supplied by including in the catalyst bed a metal oxide having no appreciable catalytic activity but which is reduced with evolution of heat under the reaction conditions, continuously or intermittently withdrawing catalyst and treating it with oxygen in excess of that required to burn off carbonaceous deposits so that reduced metal oxide is reoxidized and returning regenerated catalyst to the reaction zone. The metal oxide may form an integral part of the catalyst or may be mixed with catalyst particles. Cupric oxide is preferred and may be present in an amount of 5-25% by weight of the total catalyst. This process is preferably applied to the catalytic reforming of petroleum hydrocarbons such as a straight-run light gasoline or a platinum reformate or fraction thereof in the presence of a chromium oxide-alumina catalyst at 840-1075 DEG F., less than 50 p.s.i.g. (including subatmospheric pressures) and a space velocity of 0.1-1.0 vol./vol./hr. without added hydrogen, whether recycle or extraneous. The catalyst may be promoted by an oxide of a rare earth, bismuth, boron or germanium with or without an alkali metal, or a spinel such as cobalt chromite, copper chromite, zinc titanate or iron chromite.
