what is the process of making anthracite coal

The carbonization process of activated carbon

The carbonization process can generally be divided into the following stages. (1) The temperature in the drying stage is below 120 ° C, and the external moisture and internal moisture are released from the raw coal. At this time, the appearance of the raw coal is unchanged. (2) In the pyrolysis stage, the raw coal starts to decompose and ...
