Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased 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 ...

Answer Explanation. All tutors are evaluated by Course Hero as an expert in their subject area. Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum.

A novel process for converting coals into nonpolluting fuel oils that have very low sulfur and ash contents is described. Coals with high sulfur content can be used. The onestep desulfurization process uses rapid, turbulent, flow of hydrogen to propel coal slurry through an immobilized bed of catalyst pellets in a reactor.

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...
