Get PriceAs the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used, as well as the coke plant operating conditions.
Get PriceSGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference). We determine each element through chemical analysis and express it as a percentage of the total mass of the original coal or coke sample.
Get Pricecoal today comes from the energy that plants absorbed from the sun millions of years ago. Coal is used primarily as an energy source, either for heat or electricity. It was once heavily used to heat homes and power locomotives and factories. Bituminous coal is also used to produce coke for making steel and other industrial process heating.

Get PriceCoal carbonization is a process that yields metallurgical coke for use in ironmaking blast furnaces and other metalsmelting processes. Carbonization entails heating the coal to temperatures as high as 1300 °C in the absence of oxygen to distill out tars and light oils.
Get PriceCoking coal must also have low sulphur and phosphorous contents. Almost all metallurgical coal is used in coke ovens. The coking process consists of heating coking coal to around 10001100ºC in the absence of oxygen to drive off the volatile compounds (pyrolysis). This process results in a hard porous material coke.

Get PriceCoking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into highervalue products and, as the name implies, produces petroleum coke—a coallike material. Exports of petroleum coke accounted for about 19% of the nation's finished petroleum product exports through October 2012 with most going to China and other Asian countries.
Get PriceCoke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a highcarbon fuel for metal processing and other uses where an especially hotburning flame is needed.
