ABSTRACT:
In a system wherein a topped crude catalytic cracking system and a gas oil catalytic cracking system are operated, and the heavy cycle oils from each system are combined and the combined heavy cycle oil stream is solvent extracted to provide an aromatic extract suitable as feed for a carbon black operation, the aromaticity of the extract is increased by passing a substantial portion of the topped crude heavy cycle oil to the gas oil fractionator and recovering a heavy cycle oil from the gas oil fractionator as charge to solvent extraction.
