CATALYST CONSISTING OF GRAPHENE-SUPPORTED NANOPARTICLES FOR SELECTIVE OIL HYDROGENATION AIMED AT THE PRODUCTION OF CIS-OLEIC ACID AND THE REDUCTION OF TRANS-OLEIC ACID

摘要

A nano-catalyst which is usable in processes of vegetable oil hydrogenation for producing bio-lubricants or biodegradable plastics for producing copolymers, characterized in that it consists of an active phase composed of nickel, palladium and ruthenium, dispersed on a support consisting of graphene layers less than 1 micron, the outer surfa ce of which is covered with surfactant chains, and having a high activity and a very high selectivity for the cis-configuration of the 9-octadecenoic acid (cis-oleic acid).
