METHOD OF PRODUCING MIXTURE OF RENEWABLE FUEL COMPONENTS FROM FAT-AND-OIL RAW MATERIALS Russian patent published in 2025 - IPC C10G3/00 C10G45/58 C11C3/12 C11C3/14 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a mixture of renewable fuel components from oil and fat raw materials. Method includes: hydrodeoxygenation of a crude mixture of fat-and-oil raw materials and monoalkyl esters of simple alcohols, obtained by esterification, or re-esterification, or successive esterification and re-esterification of fat-and-oil raw materials, contained in amount of 30 to 70 wt.% of the total weight of the crude mixture, in the presence of a hydrodeoxygenation catalyst; hydroisodewaxing of the obtained hydrodeoxygenated crude mixture in the presence of a hydroisomerisation catalyst.

EFFECT: use of the disclosed invention enables to achieve 100% conversion of oxygen, increase the content of target n-alkanes C_15-18 and achieve output of liquid hydrocarbons of not less than 70% at the stage of hydrodeoxygenation of the crude mixture, as well as increasing conversion of target n-alkanes C_15-18, output and selectivity of liquid hydrocarbons at the stage of hydroisodewaxing of the hydrodeoxygenated mixture with concomitant improvement of manufacturability of each of the stages.
