| Abstract: | The coals with carbon content daf = 62,4-93,7 % were studied using thermodecomposition methods. This paper suggests a technique of pyrolysis temperature differentiation taking into account carbon content (daf, %) and the rank of coal. Simple and multiple regression equations were used to describe quantitative relations between the data Vdaf, daf, (O+N)daf, temperature Tmax and pyrolysis tar yield (Tdaf sK) for different ranks of coals. Tmax is considered as a parameter which bears information about structure, composition and properties of coals |
