Sulfur is a solid with a melting point of 115 C (239 F), a boiling point of 446 C (835 F) and a liquid density of 1.8 at melting point. Sulfur burns easily and creates Sulfur dioxide (SO 2) gas which has a choking, suffoing odor.
At high temperatures, steelmakers can use coking coal to reduce iron ore into liquid metal. But that process, which has been around since the 19th century, is a major source of the carbon dioxide
Coal plasticity is a phenomenon directly affecting the creation of coke structure. It is very much a time- and temperature-dependent transformation of the coal matrix, which allows changing the physical phase from solid to liquid-like and again into solid of different properties. The coking process, particularly in a plasticization temperature range, can be considered as a non-isothermal
