METHOD OF OBTAINING DIESEL FUEL FROM RENEWABLE RAW MATERIAL OF VEGETABLE ORIGIN (VERSIONS) Russian patent published in 2015 - IPC C10G3/00 B01J29/85 

FIELD: chemistry.

SUBSTANCE: method is realised by single-stage hydroprocessing and isomerisation with the application of a raw material of a vegetable (biological) origin, selected from vegetable oils or lipids of microalgae, in the presence of a bifunctional heterogeneous catalyst. The catalyst is represented by crystalline silicoalumophosphate with a zeolite-like structure, modified by a metal of VII group of the periodic table, with the dispersity of an introduced into the composition catalyst of metal - 14-60%, in the quantity not more than 10 wt %. The catalyst based on silicoalumophosphate with the structure SAPO-31 is preferable. In the method mixtures of a vegetable origin (fats, oils, lipids of microalgae) with hydro-purified diesel fuel are applied.

EFFECT: dilution of the vegetable raw material with mineral one makes it possible to increase the stability of action of the bifunctional catalyst and increase the time of its work.
