Relative Temperature Dependence on Physical Quantity Variance During Characterizing Coal Properties

Abstract

The natural process of any metamorphism of carbonaceous matter is a complex chain of physical-chemical transformations where the most important are the physical and chemical transformation (CH) - (C) phases and the final
structuring of the system carbon that is called metamorphism [1]. As a result of metamorphism, the oil shale is converted to a brown coal and the brown coal is converted to a coal and finally become anthracite.
