Coal refining process (Technical Report) | OSTI.GOV

The tar obtained from this process was refined by a pressure distillation in which more volatile compounds were recovered and higher-molecular weight compounds were split up before becoming volatilized. The residue produced was a coke-like substance with 0.45% ash which could be calcined to obtain a high-quality electrode coke.

Coal refining

The percent extraction or refined product, based upon the weight loss, was from 59.3 to 77.7, based upon three samples. The refined product had substantially the same carbon and hydrogen contents as the original coal, but only about 39 to 47 percent of the original sulfur content, and about 2 to 22 percent of the original ash content.

iron: | Infoplease

It usually contains 2% to 6% carbon. Scrap iron or steel is often added to vary the composition. Cast iron is used extensively to make machine parts, engine cylinder blocks, stoves, pipes, steam radiators, and many other products. Gray cast iron, or gray iron, is produced when the iron in the mold is cooled slowly.

Carbon Fuels – CharFuel® Coal Refining Process

CharFuel® coal refining converts 85%-90% of the energy in coal into clean refined products, requiring no process water and emitting no CO2. By contrast, other coal conversion technologies produce more CO 2, require process water, and are far less efficient than the CharFuel® Coal Refining Process. The CharFuel® Economics Environmentally Compliant
