"The aim is to describe organic and physical structures of maceral groups of hard coals and correlations between these structures and surface properties to express. Further, contribution of maceral groups to sorption properties of coal/coke express. Experiments of conversion of maceral groups carry out. On the basis, influence of maceral groups on behaviour of coal during conversion processes elucidate. For this purpose, 5 coals will be chosen and maceral groups separated by centrifugation. Petrographic and instrumental analysis of groups will be characterizated including non-covalent interactions, and surface measurements performed. Chosen fractions will be converted by pyrolysis, liquefaction and combustion and products analyzed. Relations between structures of coal fractions/maceral groups and properties of the products will be studied."@en . . . . . "1"^^ . . "20"^^ . . .
