To provide scientific and methodological justification for the possibility of developing means and technologies for the efficient production of hydrogen as an environmentally safe fuel from carbon-hydrogen-containing raw materials of mines and the use of resource-saving technologies for the operation of mining enterprises using secondary resources
popup.description2
The regularities of extraction of lithium and its compounds from hydromineral raw materials are established. A mathematical model and a dynamic scheme of a vibromill with vibration-impact polyfrequency excitation for efficient mechanical activation and hydrogen sorption/desorption in metal hydrides are developed. Regularities are established and methods for calculating the parameters of the process of hydrogen production in an electrochemical system with an iron anode are improved A mathematical model and its discrete analog for the production of hydrogen from coal mine methane by plasma-chemical action are developed. Regularities were established and methods for calculating the parameters of plasma-chemical processes of hydrogen-containing gases production from solid carbon-hydrogen-containing raw materials of mines were improved. The mathematical models of heat exchange and gas-dynamic processes in the evaporator, calculation of the kinetic coefficients of working fluids, movement of the working fluid in a gas turbine, heat exchange processes in the condenser of the working fluid gas flow are developed. The possibility of using resource-saving biotechnologies in coal mines is substantiated. Mathematical models of the process of non-pressure fluid flow with biological cultures floating on a free surface in a sedimentation pond and the process of free floating of biological cultures on the free surface of man-made coal deposits have been developed. A single-channel mathematical model of long-term seepage based on the scheme of capillary displacement of a gas bubble for the case of porous homogeneous bodies is developed. Mathematical models for calculating the thermodynamic cycle and energy indicators of heat and power plants, heat pump units, mini-condensing power plant - heat pump units and alternative heat and power supply systems for mining enterprises when utilizing secondary resources have been developed
