ABSTRACT:
A succession of low profile catalyst chambers each housing a reservoir of catalyst are alternately connected in sequence by openings below the levels of the catalyst reservoirs and openings thereabove. The catalyst in all reservoirs is fluidized by a gas moving upwardly therethrough. Separate portions of the sequence of chambers are operated as reactor and regenerator sections according to the gas used to fluidize the catalyst in those sections. Other portions of the sequence of chambers are used to create inert atmospheric seals between the reactor and regenerator sections. The entire apparatus is configured as a low-profile catalytic cracker wherein the fluidized flow of the catalyst moves throughout the apparatus in an alternating lifting and dropping sequence.
