The present invention provides a method for production of anode grade coke by processing crude oil feed stock in a DCU. The method comprising separation of low boiling light molecular weight components from heavier molecules and processing the same in Delayed Coker Unit after mixing with aromatic rich stream to overcome the operational issue envisaged due to processing of paraffin containing crude feed. The coke so obtained was calcined to produce an improved quality coke having lesser impurities (Sulfur
