Synthetic coking coal is produced by coking heavy hydrocarbons at a temperature greater than the temperatures which initiate cracking in the coker, and by removing the gaseous and liquid products from the coker at accelerated velocities. The thermally cracked oil produced in the coking reaction can be hydrodesulfurized to produce a low sulfur fuel oil.

A process for producing synthetic coking coal which comprises delayed coking a heavy hydrocarbon oil by: heating said heavy hydrocarbon oil in a furnace to a coking temperature of from about 380°to about 500°C. and sufficient to initiate cracking; then introducing the heated heavy hydrocarbon oil into a coking drum; maintaining the heavy hydrocarbon oil in said coking drum for a time ranging from ½to about 36 hours at said coking temperatures to effect coking thereof; introducing a diluent gas into the body of said hydrocarbon oil in the coling drum at a flow rate greater than 5 l/hr kg of heavy hydrocarbon oil to maintain the partial vapor pressure of the cracking product vapor over said heavy hydrocarbon oil in said coking drum at about 50 to about 600 mm Hg during said coking; and recovering a synthetic coking coal having a free-swelling index greater than 4 and containing 20-40 wt.% volatile matter.
