Аннотация
The group kinetics of reactions of organic sulfur compounds present in light cycle oil (LCO) in the hydrotreating process over a Co6–PMo12(S)/Al2O3 sulfide catalyst based on phosphomolybdic heteropoly acid as a function of hydrogen pressure (4, 5, and 6 MPa) at varying temperature (300–360°C in 20°C increments) and space velocities of 0.5, 1.0, and 3.0 h–1 has been studied. Total sulfur content in the feedstock and the hydrogenation products has been determined. The obtained data on the kinetics of hydrodesulfurization (HDS) reactions can be used to select optimum modes of the LCO hydrotreating process. Using the coefficient of determination and Fisher’s ratio test values, the adequacy of the pseudo-first-order and 1.5-order kinetic models and the Langmuir–Hinshelwood model has been determined. A kinetic model describing the hydrodesulfurization of LCO by hydrotreating in the presence of the Co6–PMo12(S)/Al2O3 catalyst has been selected, and the kinetic characteristics of the HDS of the compounds constituting LCO have been determined.
