Abstract
A method and apparatus for catalytic conversion of hydrocarbon feedstocks and regeneration of coked catalyst resulting from the hydrocarbon conversion reaction in which the catalyst regeneration is carried out in a combination of dense phase fluidized bed, an entrained phase regeneration zone and a second dense phase fluidized bed and the hydrocarbon conversion reaction is carried out in a high velocity short contact time dilute phase reaction zone wherein the reaction time and temperature and the regenerator temperature may be separately varied to provide and maintain optimum conversion conditions.
