What are the different types of coal? | American ...
The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.

What is CleanCoal Technology?
· If oxygen is used in a coal gasifier instead of in an aerial environment, carbon dioxide is emitted as a concentrated gas stream in syngas at high pressure. In this form, it can be captured and impounded more easily and at lower costs. On the other hand, when coal burns or is reacted in air, 80% of which is nitrogen, the resulting carbon dioxide is diluted and is more .

Coal to products
The processes for converting lignite into chemical and petrochemical raw materials are known as coaltoliquid (CtL) or coaltogas (CtG) processes. In the first step, raw lignite, which has a water content of around 50 %, is dried until its residual water content is around 12 %. It is then converted in a gasifier at high temperatures with a substoichiometric amount of oxygen, so .
