Experimental substantiation of the choice of caking additives according to the data of the study fluid non-volatile products of thermal filtration

Extracts of fluid non-volatile products isolated from the plastic layer of caking and low-caking coals of different genetic types by reductivity were first studied in detail using EPR-spectroscopy and gas chromatography-mass spectrometry (GC-MS) methods to reveal the components responsible for caking. According to a study of extracts caking additive selection was carried out. Choice of conditions and experimental verification of the effect of the proposed anthracene additive on the plastic layer formation has been established. The rate of coal decomposition in different periods of pyrolysis has been calculated by the results of derivatography method.
