Реферат:
Fossil coals of the Kuznetsk Basin of varying degrees of metamorphism were studied by the method of electron paramagnetic resonance. It is shown that in the series from brown coal to anthracite, the g-factor of the EPR signal decreases, due to the aromatization of the carbon framework and a decrease in oxygen-containing and hydrogen-containing fragments in the coals. The maximum width of the EPR spectrum is observed for coals of the middle stage of metamorphism, which indicates the presence of both aliphatic and aromatic paramagnetic centers (PCs) in their structure. Also, in the series of coal metamorphism, the concentration of PCs increases. Thus, it has been shown that in the process of coal metamorphism, a change in the electronic structure occurs, associated with the rearrangement of the carbon skeleton of the organic mass of coal (OMC) and a decrease in the amount of oxygen-containing and hydrogen-containing radicals. © Published under licence by IOP Publishing Ltd.
