Abstract:
1. A method of catalytic cracking for the production of diesel in a fluid catalytic cracking (FCC) unit having at least two FCC reactors, wherein at least one of such FCC reactors operates under conventional conditions for processing a heavy gas or oil residue feed (A) and another operates at mild conditions for processing a vegetable origin feed (B), with the same catalyst employed simultaneously in said at least two reactors, the process comprising feeding the vegetable origin feed (B) made of seeds of oleaginous plants crushed with water to obtain a suspension that is directly introduced into one reactor to produce combustible hydrocarbons that are mixed with hydrocarbons obtained from heavy gas oil or residue feed (A) to maximize diesel product of higher quality than diesel produced by feed (A) alone.
