Abstract: The article presents the physicochemical properties of "Korchagin" and "Neft Dashlari" crude oils, as well as the raw material compositions derived from them, determined using appropriate testing methods.To obtain diesel fuel distillates from raw material compositions prepared in 50:50 and 60:40 ratios, the fractions were separated at 10 °C intervals using the ARN-2 laboratory apparatus.Based on these fractions, diesel fuel distillates were compounded, and up to 30% of secondary oil refining products were added.The physicochemical properties of these compositions were then determined.The content of aromatic hydrocarbons and sulfur in diesel fuel distillates doesn't meet the specified requirements because of adding secondary refining products and requires conducting of hydrotreatment process.For the purpose of improving the quality properties of diesel fuel distillates, hydrotreatment process was conducted in continuously operating "Hungarian" type device at the experimental test site of the Institute in the presence of AGKD-400 BH catalyst, and optimal process conditions were detemined.The resulting diesel fuels meet the Euro-4 standards in terms of sulfur content (not exceeding 50 ppm), aromatic hydrocarbon content (not exceeding 20% by mass), and cetane number (48-51 units, with a minimum of 46 units) Keywords: "Korchagin" and "Neft Dashlari" crude oils, light gas oil from catalytic cracking, light gas oil from coking, hydrotreating process, AGKD-400 BH catalyst, cetane number, crystallisation onset temperature, ARN-2 laboratory apparatus
