ABSTRACT:
A method is provided for producing needle coke comprising the steps of heating green needle coke at temperatures between about 935.degree. F. and about 1,100.degree. F. for between about 10 minutes and about 24 hours, cooling the coke to below about 250.degree. F., and calcining the coke at calcination temperatures above about 2,000.degree. F.
