ABSTRACT:
A process and apparatus for fluidized catalytic cracking of heavy oils is disclosed. The long transfer line connecting the catalytic cracking reactor to the main fractionator is modified to include a cooling means, such as a quench drum or a heat exchanger. Cooling hot cracked products from the FCC reactor upstream of the main fractionator prevents thermal cracking in the transfer line, improves yields, and permits higher catalytic cracking reactor temperatures.
