OSTI ID:6414403
Clarified slurry oil feedstock is heated at temperatures above 340/sup 0/ C and preferably between 390/sup 0/ C and 410/sup 0/ C. For periods exceeding a minimum of about 2 hours, under reflux conditions and in the absence of air, so as to maximize the polymerization of light ends in the formation of petroleum pitch. An increased yield of petroleum pitch is obtained from the clarified slurry oil feedstock.
