Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the seams. It is typically hard but friable. Its quality is ranked higher than lignite and sub-bituminous coal, but lesser than anthracite. It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to 85 °C (185 °F) or higher.
Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air. Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities.
Vedanta Limited is an Indian multinational mining company headquartered in Mumbai, with its main operations in iron ore, gold and aluminium mines in Goa, Karnataka, Rajasthan and Odisha.
Petroleum coke, abbreviated coke, pet coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker units. Stated succinctly, coke is the "carbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing ". Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada's tar sands and from Venezuela's Orinoco oil sands.

Calgon Carbon Corporation is a Pittsburgh, Pennsylvania based company that manufactures and markets products that remove contaminants and odors from liquids and gases, both for industrial, municipal, and consumer markets. Calgon Carbon's product lines typically use activated carbon in various forms,
A coker or coker unit is an oil refinery processing unit that converts the residual oil from the vacuum distillation column into low molecular weight hydrocarbon gases, naphtha, light and heavy gas oils, and petroleum coke. The process thermally cracks the long chain hydrocarbon molecules in the residual oil feed into shorter chain molecules leaving behind the excess carbon in the form of petroleum coke.
Dempo Mining Corporation Limited is a prominent mining company from the western Indian state of Goa. The mineral business was founded by Mr. Vasantrao S. Dempo in 1941 along with his younger brother Mr. Vaikuntrao Dempo. Mr. Vasantrao S. Dempo was the Founder Chairman of the company, who was succeeded by his son Mr. Vasudeva V. Dempo. Currently Shrinivas V. Dempo, son of Mr. Vasudeva V. Dempo is the chairman of Dempo Group. Dempo Sports Club is linked to Dempo mining company.

Shanxi Coking Co., Ltd. (SCC) is a publicly traded coke manufacturing conglomerate in China. The company was listed on Shanghai Stock Exchange.
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.
Petkim Petrokimya Holding A.Ş. is the leading petrochemical company of Turkey. Founded on April 3, 1965, by Turkish Petroleum in 1965 in Izmir and privatized in 2008 and transferred to SOCAR. The main plant complex is located in Yarımca, Izmit. From 1985 on a second complex has been constructed in Aliağa, İzmir.
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.
Türkmennebit, also known by the translation of the name as Turkmenoil or Turkmenneft, is the national oil company of Turkmenistan. It was established by a presidential decree reorganising parts of the former Ministry of Oil and Gas in July 1996, and has its headquarters in Ashgabat. The chairman of the company is Guychgeldi Baygeldiyev.

Aluminium Bahrain B.S.C. (Alba) is the first aluminium smelter in the Middle East which started its commercial operations in 1971. The electricity that powers the process come from three power stations fueled by the nearby gasfields.
GrafTech International Ltd. is a manufacturer of graphite electrodes and petroleum coke, which are essential for the production of electric arc furnace steel and other metals. The company is headquartered in Brooklyn Heights, Ohio and has manufacturing facilities in Calais, France, Pamplona, Spain, Monterrey, Mexico, and St. Marys, Pennsylvania.
Carbon additive is a product that is added to molten steel. Carbon additive includes calcined petroleum coke, graphite petroleum coke, calcined anthracite coal, electrical calcined anthracite, and natural graphite. For the steel-making industry, the most suitable carbon additive is calcined petroleum coke with fixed carbon of 98.5%min. Sulfur in calcined petroleum coke is a crucial element, for sulfur impacts the quality of steel. The lower the sulfur, the better quality of calcined petroleum coke. The sulfur content of calcined petroleum coke is decided by the sulfur content in petroleum coke. Northeast China is the only source of low sulfur petroleum coke in the world. G-high carbon has been the origin for many trading companies and metallurgical factories when they look for qualified carbon additives.
Micro carbon residue, commonly known as "MCR" is a laboratory test used to determine the amount of carbonaceous residue formed after evaporation and pyrolysis of petroleum materials under certain conditions. The test is used to provide some indication of a material's coke-forming tendencies. The test results are equivalent to the test results obtained from the Conradson Carbon Residue test.
