| Примечания: | Title screen This paper presents the results of a study of the influence of process parameters (contact time, temperature and pressure) and hydrogen-containing gas consumption on the efficiency of catalytic hydrotreating of middle distillate fractions, performed using a mathematical model of the process. It was found that with the increase in the contact time of the raw material with the catalyst, the concentration of sulfides decreases more rapidly than the concentrations of benzothiophenes and dibenzothiophenes. The degree of conversion of sulfides, benzothiophenes and dibenzothiophenes increases with the process temperature in the range from 350 to 425 °C by 39.9; 37.5 and 19.4%, respectively. The greatest degree of desulfurization is achieved by simultaneous increase in pressure and temperature. Thus, at a temperature of 430 °C, an increase in pressure from 2.0 to 4.0 MPa leads to a decrease in the residual sulfur content from 230 to 13.5 ppm. With an increase in the consumption of hydrogen-containing gas from 42,000 to 50,000 m3/h, the efficiency of the hydrotreating process of the middle distillate fractions increases (the residual content of total sulfur in the hydrotreating product decreases from 55.9 to 24.8 ppm). |
