This petroleum coke can either be fuel grade (high in sulphur and metals) or anode grade (low in sulphur and metals). The raw coke from the coker is often referred to as green coke. [1] In this context, "green" means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the ...
The yield of coke from the delayed coking process ranges from about 18 to 30 percent by weight of the feedstock residual oil, depending on the composition of the feedstock and the operating variables. Many refineries worldwide produce as much as 2,000 to 3,000 tons per day of petroleum coke and some produce even more. [5]
Stated succinctly, coke is the "carbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing (heavy residues)". [1] Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada's oil sands and from Venezuela's Orinoco oil sands .
Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges.
Gas emission. Coke oven interior: detail (1942, USA). The coke oven is the central element of a coking plant. Horizontal ovens, which are the most commonly used (they are suitable for monitoring the various extraction stages), take the form of narrow compartments (approx. 50 cm wide), but several meters high and several meters deep.
3 C 2 H 4 → 2 C ("coke") + 2 C 2 H 6. A more realistic but complex view involves the alkylation of an aromatic ring of a coke nucleus. Acidic catalysts are thus especially prone to coking because they are effective at generating carbocations (i.e., alkylating agents). [3] Coking is one of several mechanisms for the deactivation of a ...
The refinery processed approximately 44,500 barrels of crude oil per day. The facility's main operation was to convert heavy crude oil into high quality feedstock for additional processing at the connected Rodeo Facility. Additional finished products produced at the facility were petroleum coke (carbon) and sulfur. [5]
