Abstract
High grade cokes are produced by a simple expedient such that a raw material oil is charged into a coking drum and is subjected therein to a two step operation, namely reforming of the oil and subsequent coking under bubbling into the oil of a heated non-oxidizing gas. No fluidized bed of the oil to be coked is formed.
