Until quite recently, Arctic diesel fuel was produced in accordance with GOST R 55475 with a cold filter plugging point down to –52°C using a depressant-dispersing additive. However, in the Arctic, the temperature drops to –60°C and below, and the use of depressant-dispersing additives provokes product stratification with a sharp deterioration in the properties of the lower layer. This limited the application of Arctic diesel fuel in the Arctic. For such conditions, the Ministry of Defense of the Russian Federation developed its own standards for Arctic diesel fuel without the use of depressant-dispersing additives, and suggesting values not higher than –65°C for the cloud point, pour point and cold filter plugging point. An obstacle for obtaining a product with such properties is the difficulty of simultaneously providing the required cetane number and the low temperature properties. This paper presents a method for obtaining Arctic diesel fuel with the desired properties based on deeply isomerized diesel fractions. To implement the project, the existing units at Slavneft-YANOS PJSC were analyzed, and a chain of units was assembled for primary oil refining, hydrotreating 80 atm and isodewaxing. In the course of a number of experiments new causes of the onset of cold filter plugging point were discovered, which were explained by an increase in the diesel fuel viscosity at extremely low temperatures. To reduce the viscosity of the product, hydrocracked kerosene was added to the formula. In May 2020, permits were received from the Ministry of Defense of the Russian Federation, and in October 2021, for the first time in the Russian Federation and in the world, the first industrial batch of 3,000 tons was successfully produced.

直到最近，北极柴油燃料的生产符合 GOST R 55475 标准，其冷过滤器堵塞点低至 –52°C，使用抑制剂分散添加剂。然而，在北极，温度降至 –60°C 及以下，并且使用抑制剂分散添加剂会引起产品分层，下层性能急剧恶化。这限制了北极柴油在北极的应用。针对这种情况，俄罗斯联邦国防部制定了自己的北极柴油标准，不使用抑制剂分散添加剂，并建议浊点、倾点和冷滤器堵塞值不高于 –65°C观点。获得具有这种特性的产品的一个障碍是难以同时提供所需的十六烷值和低温特性。本文介绍了一种基于深度异构化柴油馏分获得具有所需性能的北极柴油燃料的方法。为实施该项目，对 Slavneft-YANOS PJSC 的现有装置进行了分析，并组装了一系列装置，用于初级炼油、加氢处理 80 atm 和异脱蜡。在许多实验过程中，发现了冷滤点出现的新原因，这可以通过在极低温度下柴油粘度增加来解释。为了降低产品的粘度，将加氢裂化煤油添加到配方中。2020年5月，
