Description Coals blends with all possible combinations of high- and low-sulfur coals of the same rank
and petrographic composition were pyrolysed in centrifugal field, allowing to separate solid, fluid
and gaseous products. It has been shown that replacement of the low-sulfur by the high-sulfur
coking coal of the same rank (≈83–88 % Cdaf) in blends leads to substantial increasing of fluid
products yield which can be of great practical value. Using the EPR and DRIFT-spectroscopy
methods the structural peculiarities of the obtained products have been studied. An apparent
correspondence between the content of sulfur in coal, content of paramagnetic centers in plastic
layer and coal coking ability has been discovered.
