Abstract:
The fluid catalytic cracking process according to the present invention includes a first step of feeding a feedstock to a first fluid catalytic cracker, and catalytically cracking the feedstock in the first fluid catalytic cracker, so as to produce a fraction (LCO) having a boiling range of 221 to 343° C. and having a total aromatic content of 40 to 80 volume %; and a second step of feeding an oil to be processed containing the fraction to a second fluid catalytic cracker having a reaction zone, a separation zone, a stripping zone, and a regeneration zone, and catalytically cracking the oil in the reaction zone of the second fluid catalytic cracker, in the presence of a cracking catalyst, at an outlet temperature of the reaction zone of 550 to 750° C., a contact time between the oil and the catalyst of 0.1 to 1 second, and a catalyst/oil ratio of 20 to 40 wt/wt.
