Abstract: AN IMPROVED COKE FOR THE PRODUCTION OF GRAPHITE ELECTRODES IS PRODUCED FROM A PETROLEUM COKING FEEDSTOCK CONTAINING 0.01% BY WEIGHT OR MORE OF SPENT CRACKING CATALYST BY REDUCING THE SPENT CRACKING CATALYST CONTENT OF THE PETROLEUM COKING FEEDSTOCK TO LESS THAN 0.005% BY WEIGHT PRIOR TO THE COKING OF SAID FEEDSTOCK. WHEN A SMALL AMOUNT OF COLLOIDAL GRAPHITE IS ADDED TO THE PETROLEUM COKING STOCK HAVING LESS THAN 0.005% BY WEIGHT OF SPENT CRACKING CATALYST JUST BEFORE IT IS COKED, AN ADDITIONAL IMPROVEMENT IN THE COKE IS OBTAINED.
