Abstract:
1. Process for producing base oil, characterized in that a) feedstock comprising at least one alcohol selected from the group consisting of primary and secondary saturated and unsaturated C1-C40 monohydroxy alcohols, diols, and polyols, is condensed in the presence of a basic catalyst at a temperature ranging from 200 to 300° C. to obtain a condensation product comprising branched monofunctional and branched poly-functional alcohols, respectively, b) the condensation product is hydrodeoxygenated in the presence of a hydrodeoxygenation catalyst under a hydrogen pressure ranging from 0.1 to 20 MPa at a temperature ranging from 100 to 500° C. to obtain a saturated hydrocarbon, and then c) the non-branched carbon chains of the hydrodeoxygenated product are hydroisomerized in the presesence of an isomerization catalyst under a hydrogen pressure ranging from 0.1 to 20 MPa at a temperature ranging from 100 to 500° C. to obtain a base oil, wherein said base oil comprises:
