Abstract
An apparatus for the fluidized catalytic cracking of a hydrocarbon feedstock comprises a riser reactor and a collar positioned along the same axis as the downstream end of the riser reactor. The collar is further positioned in close proximity to, but not in contact with, the riser reactor such that an annular space is defined between the riser reactor and the collar. The collar has a diameter greater than the diameter of the riser reactor at its downstream end and communicates directly and laterally with the inlets of the cyclone separation system. The riser reactor may or may not include a flow reversal cap to redirect the flow of the hydrocarbons and the catalyst.
