Difference Between Coking Coal And Thermal Coal

Sep 10, 2020 The key difference between coking coal and thermal coal is that coking coal is mainly used to produce high-quality coke, whereas thermal coke is important in producing electricity.. Coal is a type of sedimentary rock that is combustible. It appears in black or brownish-black colour. Mostly, coal contains carbon and variable amounts of other chemical elements such as hydrogen, sulfur, oxygen ...
