Abstract
An improved coking process is described wherein a feedstock comprising residual oil is passed into a coking zone along with a highly aromatic oil such as pyrolysis tars or a decanted oil produced from a fluidized catalytic cracking zone in a concentration resulting in the feedstock having froma bout 5 to about 20 percent by weight of highly aromatic oil. The yield of coke is thereby reduced.
