Petroleum coke, also known as ''petcoke'' is a by-product of the oil refining process. ... from crude oil, the excess is superheated through a process called ''coking''. ... It is commonly used in power plants and kiln fuels for the production of cement. Anthracite. Anthracite is another variety of .
Steelmaking has existed for millennia, but it was not commercialized on a massive scale until the late 19th century. The ancient craft process of steelmaking was the crucible process. In the 1850s and 1860s, the Bessemer process and the Siemens-Martin process turned steelmaking into a .
1.2 Anthracite Coal Combustion 1.2.1 General1-5 Coal is a complex combination of organic matter and inorganic ash formed over eons from successive layers of fallen vegetation. Coals are classified by rank according to their progressive alteration in the natural metamorphosis from lignite to anthracite. Coal rank depends on volatile
Jun 22, 2016· In either coke or non-coked coal, the quality of the coal affects the quality of the steel. Metallurgical coke is made from bituminous coals by a distillation process. Ash deposited by the coal must be kept to a minimum, preferably below 10% of the original mass. The ash can lower furnace temperatures and leave non-combustible materials.
South Africa exports lower-quality, higher-ash anthracite to Brazil to be used in steel-making. [citation needed] Sizing and grading. Anthracite is processed into different sizes by what is commonly referred to as a breaker. The large coal is raised from the mine and passed through breakers with toothed rolls to reduce the lumps to smaller pieces.

Apr 24, 2013· Alternatively, the Hisarna process uses coal directly rather than making coke, reducing coal input by around 20%. (1) The steel industry worldwide is putting serious effort into finding ways of reducing carbon emissions from steel making – within the current economic framework. But we are looking for something that could replace coal altogether.
Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that produces coal for coking, to ensure a stable and low-cost supply.
