Abstract
The main approaches to developing a reactor block for the hydrodesulfurization of diesel fuels are considered taking into account the reactivity of the organosulfur components in the diesel fuel and the formation of pseudocomponents, which conventionally combine the group of organosulfur components. As the concentration of easily or difficult-to-hydrate sulfur-containing components in the raw material increases, the role of the substance limiting the quality of diesel-fuel purification can go from an easily hydrated to a difficult-to-hydrate pseudocomponent and vice versa. The efficiency of the operation of five variants of the reactor of hydrotreating units is compared. It is shown that, from the standpoint of minimizing catalyst loading, the two-reactor scheme of the hydrotreating process with separate feeding of low-boiling and high-boiling fractions of straight-run diesel fuel to the reactors is optimal. The necessity of determining the temperature boundary of their division, considering the qualitative and quantitative composition of these fractions in terms of organosulfur substances, has been substantiated.
