Abstract
A delayed coking process is provided in which the fresh hydrocarbonaceous oil feed is divided into at least two streams. One stream is introduced directly into the preheating zone of the coking zone and one stream is introduced into the coker product fractionator. The fractionator bottoms fraction is recycled to the preheating zone. The given fresh feed splitting configuration permits decreasing the recycle rate of the heavy coker product and increasing liquid yield.
