Petroleum coke (often abbreviated petcoke) is a carbonaceous solid derived from oil refinery coker units or other cracking processes.^[1] Other coke has traditionally been derived from coal. This article belongs in one or more categories. ... View of Shell Oil Refinery in Martinez, California. ... There are very few or no other articles that link to this one. ... Factory of Shukhov cracking process, Baku, USSR, 1934 In petroleum geology and chemistry, cracking is the process whereby complex organic molecules such as kerogens or heavy hydrocarbons are broken down into simpler molecules (e. ... Coke Coke is a solid carbonaceous material derived from destructive distillation of low-ash, low-sulfur bituminous coal. ... Coal Coal (IPA: ) is a fossil fuel formed in swamp ecosystems where plant remains were saved by water and mud from oxidization and biodegradation. ...

Marketable coke is coke that is relatively pure carbon and can be sold for use as fuel (ie fuel grade coke), or for the manufacture of dry cells, electrodes (ie anode grade coke). Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminum industries. Catalyst coke is coke that has deposited on the catalysts used in oil refining, such as those in a catalytic cracker. This coke is impure and is only used for fuel.

Its high heat and low ash content make it a good fuel for power generation in coal fired boilers, but petroleum coke is high in sulphur and low in volatile content which pose some environmental and technical problems with its combustion. In order to meet current North American emissions standards some form of sulphur capture is required. Fluidized bed combustion is commonly used to burn petroleum coke. Gasification is increasingly used with this feedstock (often using gasifiers placed in the refinery themselves). // Ash may refer to: Ash, the incombustible solid remains of a fire, the residual debris produced by incineration. ... A boiler is a closed vessel in which water or other fluid is heated. ... For the chemical element see: sulfur. ... This article describes a highly specialized aspect of its subject in the Terminology and legal definitions section. ... For the chemical element see: sulfur. ... Fluidized bed combustion (FBC) is a combustion technology used in power plants. ... For the water carbonator, see Gasogene. ...
