FIELD: chemistry.SUBSTANCE: claimed invention relates to methods (processes) and systems for processing triglyceride-containing oils of biological origin with obtaining base oils and fuels for vehicles. Method of obtaining base oil and Diesel fuel includes the following stages: a) processing triglyceride-containing vegetable oil with realisation of oligomerisation and deoxygenation of components on the basis of unsaturated fatty acids, contained in it, with obtaining oligomerised mixture, with said processing including hydration and further removal of water; b) isomerisation of oligomerised mixture above isomerisation catalyst with obtaining isomerised mixture, and isomerised mixture contains base oil component and Diesel fuel component, and isomerised mixture contains, at least, 10 wt % of alkanes with number of carbon atoms 30 or higher, and c) distillation of isomerised mixture with obtaining base oil and Diesel fuel, where oligomerised mixture includes oligomer component, and said oligomer component includes, at least, 50 wt % of dimeric compounds.EFFECT: processing of oils of biological origin into wide range of products with good level of properties.11 cl, 4 dwg, 1 ex |
