The use of oxidized coal in coking batch increases the analytical moisture content and packing density; impairs the plasticity and ductility; reduces the carbon and hydrogen content; increases the oxygen content; reduces the gross coke yield and the yield of tar, benzene, and unsaturated...
Test data for coke in production conditions indicate the relation between its quality characteristics. A comprehensive index for the assessment of metallurgical coke is proposed.
Existing methods of determining the porosity of special coke obtained from Shubarkol’ D coal are analyzed. Selection principles for a rational method are established, and the calculation results are compared. Results given by various methods for the porosity of special coke after fast and slow...
The quality of low-ash coal and semicoke is analyzed in terms of the requirements on carbon reducing agents in silicon production. Their prospects for the production of high-purity silicon are discussed.
Thermodynamic and topological analysis identifies the factors responsible for the naphthalene losses with the phenol fraction in the rectification of naphthalene-bearing coal-tar fractions and the losses with the primary fraction in the rectification of the naphthalene fraction or a broad...
The synthesis of copper and cobalt phthalocyanines from coke-plant waste—specifically, the primary distillation fraction from phthalic anhydride—has been developed. The introduction of this process in the phthalic-anhydride shop at coke plants provides the opportunity for resource and energy...
A technology for the utilization of polymer and rubber wastes in mixtures with fuel shales is proposed. Adding the wastes to the fuel shales improves the properties of the products.
Experiments are conducted to improve the coal preperatiom dumps at PAO Avdeevskii Koksokhimicheskii Zavod and to recultivate and utilize the wastes rock by means of humic preparations from lignite and other wastes rock. Reclamation and utilization of blends of industrial wastes rock proves...
The possibility of using carbon materials derived from renewable plant sources in the mechanochemical synthesis of titanium carbide and the manufacture of sorbents for industrial wastewater purification is considered.
