METHOD OF PRODUCING BRANCHED HYDROCARBON COMPONENT Russian patent published in 2010 - IPC C10M105/04 C10M109/00 C10M177/00 C10G3/00 C07C1/20 C10N20/02 C10N70/00 

FIELD: chemistry.

SUBSTANCE: starting raw material consisting of at least one alcohol selected from a group consisting of primary and secondary saturated and unsaturated C1-C40-monobasic alcohols, diols and polyols is condensed in the presence of 1-20 wt % base catalyst selected from hydroxides and alkoxides of alkali and alkali-earth metals and metal oxides, combined with 0.05-1 wt % cocatalyst containing salt of chromium (III), manganese (II), iron (II), cobalt (II), lead (II) or palladium or tin oxide or zinc oxide,at temperature between 200 and 300°C. The condensation product undergoes hydrodeoxygenation in the presence of a hydrodeoxygenation catalyst at hydrogen pressure from 0.1 to 20 MPa and temperature from 100 to 500°C, and then undergoes hydroisomerisation in the presence of an isomerisation catalyst at hydrogen pressure from 0.1 to 20 MPa and temperature from 100 to 500°C.

EFFECT: use of the given method of producing base oil enables to lower impact on the environment.
