    Abstract: A delayed coking process in which the overhead vapors from a delayed coking drum are separated into light hydrocarbon products and a gas oil, and in which the gas oil is hydrotreated after being separated from the light hydrocarbon products. The hydrotreated gas oil is then combined with coker feedstock and fed to the coking drum. The process produces a coke capable of producing a graphitized product having a lower longitudinal coefficient of thermal expansion than that of the coke product produced from the same feedstock by the same process but without the hydrotreating step.

    Abstract: Pulverized coal is slurried with hydrogen donor solvent at atmospheric pressure and fed directly into a coker furnace and coking drum. Overhead products from the coking drum are fractionated, and a portion thereof is hydrogenated and used as donor solvent. Coke is calcined in a vertical shaft calciner, and calcined coke is contacted with steam in the calciner to produce hydrogen. The hydrogen is used to hydrogenate the donor solvent.

    Abstract: A process for producing a distillable hydrocarbonaceous stream, fuel gases and blast furnace grade coke from a heavy, high sulfur, crude oil by producing delayed coke from at least a portion of the crude oil; crushing at least a portion of the coke to provide a finely divided coke feedstock to a briquetting operation where the finely divided coke is briquetted using crude oil or topped crude oil as a binder to produce briquettes of a size from about 3/4 inch to about 3 inches with the resulting briquettes being passed to a high temperature vertical calciner where the solids are desulfurized to produce a strong blast furnace grade coke. The distillable stream and fuel gas stream are recovered from the delayed coking operation, the vertical calciner and optionally a crude oil topping operation. In some instances coke particles in the size range from about 3/4 inch to about 3 inches may be passed directly to the calciner without crushing and briquetting. However, it is preferred to crush and briquette substantially all of the coke.
