Analysis, Modeling and Optimization of Reactors for Hydrotreatment of Diesel Fuel with Removing Organosulfur Impurities.

The disadvantages of the reaction units of hydrotreatment plants are considered and an approach to process improvement by means of the characteristics of hydrodesulfurization reactions of organosulfur impurities of various nature is substantiated. The mathematical modeling method demonstrates that when dividing the feedstock into three wide fractions, each containing several narrow fractions, differential hydrotreatment of these wide fractions is ensured by a reduction in the catalyst load in the reactor unit of the facility.
