Conclusions 1. The long operation time of an industrial hydropurification unit confirmed the correctness of the recommendations of the Bashkirian Scientific Research Institute of Oil Industry and the All-Union Scientific Research Institute of Oil Industry as to the possibility of reducing the hydrogen consumption. 2. The yearly average of the hydrogen consumption in 1963 during the hydropurification of straight-run and secondary diesel fuel at the reactor temperature of 380°C and the pressure of 28–36 atm amounted to 0.46, i.e., was 1.5 times lower than the design value. 3. Lowering of the pressure in the reactor from 34–36 to 28–30 atm enabled us to reduce the hydrogen consumption 1.3 times without deterioration of the product quality. The operation time of the catalyst between regeneration was eight months. 4. It has been shown that the activity of the catalyst drops faster in the first than in the next reactors. The degree of removal of sulfur compounds drops below 50% in the first reactor when 1200 t of feed per 1 m3 of catalyst have been treated, whereas in the second reactor this level is reached after purification of 2300 t of feed per 1 m3 of catalyst.
