    Abstract: An improved process for the delayed coking of a heavy residual hydrocarbon feedstock to reduce the coking induction period and to enhance the coking process relative to the processes of the prior art is achieved by mixing a sufficient volume of a paraffinic solvent having the formula CnH2n+2, where n=3 to 8 with the heavy feedstock to disturb the equilibrium of asphaltenes in the solution of maltenes in order to flocculate substantially all of the solid asphaltenes particles to thereby increase the yield and quality of valuable liquid products and minimize undesirable cracking reactions that result in high molecular weight polymers and the formation of coke.
