12.3. Types of Coal-derived Chemicals | netl.doe.gov

The processes for production of specific chemicals from coal are typically proprietary systems using specialized process systems. In the following discussion, some of the processes for important chemicals such as formaldehyde, olefins, etc. are presented. Methanol (MeOH) is of course another important primary chemical made from coal syngas; however, it is also a liquid fuel in its own right ...

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a high-carbon fuel for metal processing and other uses where an especially hot-burning flame is needed. Coal is also used in manufacturing. If coal is heated the gases, tars, and residues produced can be used in a number of manufacturing ...

Coal Gasification | HowStuffWorks

This causes the coal to undergo different chemical reactions. First, partial oxidation of the coal's carbon releases heat that helps feed the gasification reactions. The first of these is pyrolysis, which occurs as coal's volatile matter degrades into several gases, leaving behind char, a charcoal-like substance.
