Abstract

The results of the investigation of radiation-thermal hydrodesulphurization of brown coal in presence of methane under accelerated electrons with a dose rate P=350 Gy/s in the intervals of temperatureT=200–500 °C, absorbed dose up to 60 kGy are presented. It has been established that at the more favourable conditions (T=400–450 °C,D>60 kGy) about 80% of sulphur is removed from the coal and in the solid product sulphur decreased up to 1.0–1.1%. In these conditions the selectivity of desulphurization processes iss=2.6–3.8 and energy consumption towards removal of sulphur isE=0.5–0.6 kW h/kg. The mechanism of selective activation by irradiation for the desulphurization process is discussed.
