Abstract
An apparatus for downflow fluid catalytic cracking is described, which comprises a regenerated catalyst riser carrying regenerated catalyst and a carrying fluid, those being directed through a crossover section to a distributor that will centrifuge gas and separate catalyst from carrying fluid, the catalyst being directed to a downflow reactor through a distributing basket provided with perforations. The upper part of the reactor is provided with feed injectors, which atomize the feed so that feed vaporization and feed and catalyst admixture is optimized. After the cracking reaction in downflow reactor, reaction products are separated and spent catalyst is directed to stripping and regeneration sections. The FCC process carried out in the apparatus is also described.
