【 摘 要 】

The paper studies oxidative desulphurization of oils with an initial sulphur content of 1.98 wt% by hydrogen peroxide on a carbon-black (CB) catalyst coated by a combination of cobalt and nickel. The results demonstrate the effects of temperature and duration of the process, amount of the catalyst and the nature of the selected extractant on the removal efficiency of oxidized sulphur compounds. The extractant was represented by a solution of dimethylformamide (DMF) with water (10 vol%). The maximum removal degree of sulphur exceeded 70% and was achieved in 90 minutes with an amount of the catalyst of 1.0-1.3 wt.% and a temperature of 50 °C.
