Get PriceFixed-carbon content. The fixed-carbon content of a coal is determined by subtracting the percentages of moisture, volatile matter, and ash from a sample. Since gas-solid combustion reactions are slower than gas-gas reactions, a high fixed-carbon content indicates that the coal will require a long combustion time.
Get PriceCoal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.

Get PriceCoking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum coke—a coal-like 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 PriceCoking vs. Steam: Coking coal, also known as metallurgical coal, has low sulfur and phosphorus content and can withstand high heat. Coking coal is fed into ovens and subjected to oxygen-free pyrolysis, a process that heats the coal to approximately 1,100 degrees Celsius, melting it and driving off any volatile compounds and impurities to leave pure carbon.
[PDF]Get PriceMining Rheology of Coal. Rheological testing determines the flow characteristics of materials. Coking coals swell, soften and then re-solidify to form coke when heated in the absence of air. These rheological properties of coal in the coke oven have a major impact on the resultant coke quality.
Get Price6.9. Common coking coal tests. The three main factors which can contribute to the change/deterioration of coking coal properties over time include: 1. exposure to air, 2. exposure to moisture, 3. rehandling (size reduction) of the coal.
[PDF]Get PriceDec 10, 2013 · There are two main determinants of coal value. The first, total ash content, is used to distinguish high-quality, relatively high purity coals used for producing coke (a source of carbon) for smelting metals, referred to somewhat uncreatively as ...
Get PriceCoke is produced by heating coking coals up to 1000 to 1200 °C for several hours in coke ovens to drive off volatile compounds and moisture. For every ton of coke around 3.5 to 5.0 GJ of energy (IEA, 2007. p.110) and around 1.6 ton of coking coal is used (IEA, 2009, p.52).

Get PriceCoal trade. Coal is traded all over the world, with coal shipped huge distances by sea to reach markets. Overall international trade in coal reached 1333.5 Mt in 2016; while this is a significant amount of coal it accounts for about 18% of total coal consumed. Most coal is used in the country in which it is produced.
Get PriceCoal is being used in power generation, the manufacturing of cement, iron and steel. Coking coal is used to produce coke, which in turn is used to produce pig iron. Coal used for energy generating is declining due to an increase in the use of natural gas and nuclear power. The overall coal production however is increasing, for other purposes.
Get PriceAccording to the NSC prediction such a coal should produce a coke with a CSR of about 50. The actual value of CSR for this coal is 32 (NSC, 1982). Later studies by NSC have suggested that deviation from the predicted pattern of Figure 3, is caused by the catalytic nature (chemical composition) of the ash, and variation of coking
