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.

本文介绍了确定同时脱芳构化和加氢脱蜡反应的最佳条件的研究结果，以评估在 LCh-24/7 装置的脱蜡段中大规模生产用于钻井液的低粘度烃基无循环。研究了关键因素之一，即温度对反应过程的影响。这项研究是在实验室单元中使用含铂脱蜡催化剂进行的，用于研究加氢过程。发现关键因素是 280°С，此时加氢脱蜡反应开始优于脱芳构化反应。该研究使柴油燃料中芳香族化合物的含量降低到 7% 水平成为可能，这是进一步研究确定其他参数影响的基础，
