This paper presents the results of research for determining the optimal conditions for simultaneous dearomatization and hydrodewaxing reactions to evaluate large-scale production of low-viscosity hydrocarbon bases for drilling fluids in the dewaxing section of an LCh-24/7 unit without recycle. The Influence of one of the key factors, namely, temperature, on the course of the reaction was studied. This research was conducted using a platinum-containing dewaxing catalyst in a laboratory unit for the study of hydorprocesses. It was found that the key factor is 280°С at which hydrodewaxing reactions begin to prevail over dearomatization reactions. The research made it possible to reduce the content of aromatic compounds in diesel fuel to the 7% level, which is the basis for further research to determine the influence of other parameters, such as pressure and volume feed rate.
