Deep processing of organic mass of finely dispersed coal waste

The technological and technical possibility of deep processing of coal by its liquefaction using the methods of extreme mechanochemical and physical effects has been determined; recommendations have been developed for the applied use of the obtained materials in heat power engineering. The organic p...
