Determination of Optimum Conditions Effect of Coal Oxidative Desulfurization to Produce Pulverized Coal

“…In previous studies, the process of oxidative desulfurization for various types of coal was investigated, in particular: brown coal [24][25][26][27], black coal of low [33,34], medium [28][29][30][31] and high (including anthracite) [32] degrees of metamorphism. These works were carried out to obtain a desulfurized product (coal with a satisfactory sulfur content), which is proposed to be used as a raw material for thermal power plants.…”
