ABSTRACT:
A process is disclosed for converting hydrocarbons with a particulate catalyst containing a crystalline solid which has pore openings and maximum cage dimensions of 5.5-7.0 Angstroms; an active metal with both dehydrogenation activity and oxidation activity is disposed within the interior of crystals of the crystalline solid; the catalyst is cycled between a reactor and a regenerator, and the active metal is used for (1) selectively dehydrogenating paraffins and aromatizing aliphatics in the reaction zone while large-diameter coke-forming hydrocarbons are inhibited from contacting the metal, (2) facilitating catalyst regeneration by accelerating combustion of carbon from within the pores of the crystalline solid in the regenerator, so as to assure very low residual carbon levels within the crystalline solid in regenerated catalyst; and (3) oxidizing carbon monoxide in the regenerator to make available additional heat to compensate for endothermic conversion reactions in the cracking reactor.
