Anthracite from Omsukchan Basin is investigated by up-to-date analytical methods. Information is provided regarding the composition and calorific value of the anthracite, its petrographic characteristics, the quality of its mineral component, and its thermomechanical and physicochemical...
The basic composition and thermal characteristics of Mongolian coal samples are determined: specifically, two coal samples from the Tavantolgoi and Nariinsukhait fields; and two lignite samples from the Baganuur and Shivee-Ovoo fields. Their reactivity in semicoking is studied. The composition...
The reagent flotation of regular coal by means of liquid containing gas microbubbles is considered. Various sequences of microbubble supply to the flotation chamber are tested and characterized. The supply of gas–liquid microbubble mixture to coal pulp that has previously been dosed with...
Attention focuses on the possibility of producing petroleum coke from batch containing heavy tar with the addition of residue from the hydraulic processing of petroleum. The resulting samples of petroleum coke are subjected to technical analysis, and their microstructure is assessed. The quality...
The softening temperature of coal pitch obtained by coal-tar distillation is investigated as a function of three parameters: the rate of tar heating; the temperature of isothermal holding; and the holding temperature. A model in the form of a regression equation satisfactorily describes the...
