Abstract
Methods and apparatus for fluid catalytic cracking (FCC) of a hydrocarbon feedstock includes a first reactor (), a second reactor (), and a regenerator assembly () shared and connected with the two reactors. The regenerator assembly () includes a regenerator vessel which has a partition () dividing the regenerator vessel into a first subunit () and a second subunit (); a plurality of regenerator inlets for receiving a first spent catalyst and second spent catalyst by the first subunit () and the second subunit (); a plurality of regenerator inlet for receiving a first spent catalyst and a second spent catalyst by the first subunit () and the second subunit () respectively; an air controller () to allow for has flow to an air distributor () for supply of the gas to the first subunit () and the second subunit () to combust coke deposited on the first and the second spent catalyst, separately, to a desired degree to generate a fully and a partially regenerated catalyst.
