ABSTRACT:
A method is provided for producing needle coke comprising the steps of heating green needle coke at temperatures between about 875.degree. F. and about 1,200.degree. F. for between about 10 minutes and about 24 hours, and, without first allowing the temperature of the coke to cool below about 250.degree. F., calcining the green needle coke at calcination temperatures above about 2,000.degree. F.
