Delayed coker - Wikipedia
A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.

Pet coke | McKinsey Energy Insights
Pet coke. Also known as: coke, refinery coke, petroleum coke. Pet coke is the solid carbon byproduct of cracking units such as the the FCC and coker unit.. In an FCC, coke forms on the catalyst and is burned off as fuel for the FCC process, resulting in no net production of coke as a product.. In a delayed coker, resid is thermally cracked to produce lighter, more desirable products.
