Modification of coal properties under the influence of microwave radiation

The paper presents the results of research on the treatment of bituminous coal with microwave radiation. Experiments were conducted using an experimental laboratory setup, which consisted of a modified household microwave oven. Following the experiments, a reduction in the mass of the studied samples was observed, as well as changes in their external appearance. Based on the obtained data, it can be concluded that the application of microwave radiation in the processing of bituminous coal enables a reduction in the amount of harmful emissions into the environment, increases the energy efficiency of the fuel, and reduces the time required to prepare coal for use in various industries.
