Abstract
A fluid catalytic cracking (FCC) process for cracking multiple feedstocks in a FCC apparatus comprising a first set of feed distributors having first distributor tips and a second set of feed distributors having second distributor tips is provided. A first feed is injected into the riser from first distributor tips. A second feed is injected into the riser from second distributor tips. The first distributor tips and the second distributor tips are positioned at different radii in the riser. The first feed and the second feed are cracked in the riser in the presence of an FCC catalyst to provide a cracked effluent stream. The first distributor tips and the second distributor tips are located into a region of lower catalyst density and a region of higher catalyst density respectively in the riser.
