CONVERSION OF VEGETABLE OILS TO BASE OILS AND TRANSPORTATION FUELS Russian patent published in 2013 - IPC C10G3/00 C10G69/12 C10L1/02 

FIELD: chemistry.

SUBSTANCE: present invention relates to methods and systems for processing triglyceride-containing, biologically-derived oils to obtain base oils and transportation fuels. The method comprises the following steps: a) processing a triglyceride-containing vegetable oil to effect oligomerisation of unsaturated fatty acid components contained therein so as to obtain an oligomerised mixture; b) isomerising the oligomerised mixture over an isomerisation catalyst to obtain an isomerised mixture, wherein the isomerised mixture comprises a base oil component and a diesel fuel component; c) removing water from the isomerised mixture to obtain a dry isomerised mixture, wherein the dry isomerised mixture comprises at least 10 wt % alkanes having 30 or more carbon atoms; d) separating the dry isomerised mixture into a lower boiling fraction from which diesel fuel is subsequently derived, and a higher boiling fraction; and e) subsequently further isomerising at least a portion of the higher boiling fraction to obtain a base oil. A system for producing base oil and diesel fuel is also disclosed.

EFFECT: providing multiple product streams of given quality.
