Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

After thermal upgrading, the coal is put through a deep bed stratifier cleaning process to separate the pyrite rich ash from the coal. When fed a typical low rank western coal, the SynCoal process can provide a product with a heating value of up to 12,000 BTU/lb with moisture and ash contents as low as 1% and %, respectively [ 100 ].

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]
