FIELD: oil refining.
SUBSTANCE: invention relates to catalysts for isodewaxing diesel fractions for producing arctic diesel fuel. Catalyst for isodewaxing of diesel fractions consists of a support containing, wt.%: USY type zeolite 0.01–15, amorphous aluminosilicate 5–15, MFI or “ЦВН” type zeolite 5–45, MTT type zeolite 0.01–30, MEL type zeolite 5–30, gamma aluminum oxide—the rest up to 100, and nickel and molybdenum oxides deposited on the support in amount of 1.0–5.0% and 3.0–11.5%, respectively, of the weight of the support.
EFFECT: reduced cracking and improved isomerisation functions of the catalyst, ensuring stability of the catalyst to deactivation in the presence of sulfur and nitrogen compounds in the feed.
