METHOD OF HYDROAMELIORATIVE TRIGLYCERIDES OF FATTY ACIDS IN THE MIXTURE WITH OIL FRACTIONS Russian patent published in 2018 - IPC C10L1/00 C10G45/04 C10G45/06 C10G65/04 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for joint hydroblasting of fatty acid triglycerides and straight-run diesel fraction on sulfide catalysts in order to obtain low-sulfur hydrocarbon fractions and it can be used in the petroleum industry. Resulting hydrocarbon fractions can be directly used as diesel fuel, or can be further processed, if necessary, during the isomerization process in order to improve the low temperature properties. Method for hydrotreating triglycerides of fatty acids (TLC) in a mixture with petroleum fractions at an elevated temperature and pressure of hydrogen on sulfide catalysts MoS₂/Al₂O₃ and NiMo/Al₂O₃ in two stages is proposed, where in the first stage hydrotreating the straight-run diesel fraction in the presence of sulphide NiMo/Al₂O₃ catalyst, then the obtained mixture of hydrocarbons, hydrogen and hydrogen sulfide is mixed with fatty acid triglycerides and a hydrodeoxygenation reaction is carried out in the presence of a sulfide catalyst MoS₂/Al₂O₃.

EFFECT: high efficiency of the process of joint hydrotreating of diesel fractions and triglycerides of fatty acids.
