סיכום:Title screen
Thermal processing of coal, which is one of the most widespread energy sources, represents an important approach to greening the energy sector due to the possibility of obtaining products with high energy density and low greenhouse gas emissions. However, the relatively high duration of conventional thermal treatment methods (such as traditional pyrolysis) leads to an increase in both energy consumption and the cost of secondary products that requires the search for alternative solutions in terms of reducing specific energy consumption for the process implementation. This paper represents the results on intensifying microwave pyrolysis of hard coal by applying microwave radiation absorbers acting as process catalysts for reducing the overall processing time. When applying such absorbers based on metal powders (copper and iron) and their oxides (CuO, Cu2O, FeO, Fe2O3) in a mixture with hard coal, the process initiation time is found to decrease by 56–96 %, while the process duration shortens by 25–48 % depending on the type of metallic additive and its dispersity. It allows reducing the specific energy consumption for microwave processing of hard coal by 55–84 % and the cost of energy component (more than 2 times) for producing 1 MJ of generated gas. The production of cheaper and environmentally friendly (with low content of CO2 component) gas opens wide prospects for further practical implementation of the proposed method of hard coal microwave processing
