A method for reducing furnace fouling in a delayed coking process comprising (a) supplying at least one feed to a delayed coking unit comprised of coker furnace, at least two coke drums and a coker fractionator, (b) increasing the aromaticity of the feed to produce a modified stream by combining with the feed upstream of the coker furnace at least one added stream selected from the group consisting of an aromatic gas oil, a hydrotreated aromatic gas oil and combinations thereof, (c) introducing the modified feed stream into the coker furnace, d) heating the modified feed stream to a coking temperature in the coker furnace to produce a heated modified stream, and e) transferring the heated modified stream from the coker furnace to a coke drum.

Method for reducing fouling of coker furnaces

A delayed coking process for producing more uniform and higher quality coke by increasing the drum inlet temperature of the feedstock at least 2&#xb0; F. during a fill cycle.
