Abstract: A method of producing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a medium pore size of at least about 10 nm with an acid to produce a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support to produce a noble metal-containing silica support, and optionally contacting the noble metal-containing silica support with a chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as, phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.

Abstract: A method for producing a higher alcohol from a waste plastic feedstock is disclosed, comprising: (a) providing a hydrocarbon feed stream comprising a pyrolysis oil feed obtained from pyrolysis of plastic waste, wherein the pyrolysis oil comprises at least 20 wt % higher olefins with a carbon number in the range C5-C20, based on its total hydrocarbon content; (b) contacting the hydrocarbon feed stream with synthesis gas under hydroformylation conditions in the presence of a hydroformylation catalyst and recovering a hydroformylation product; (c) subjecting the hydroformylation product to hydrogenation and/or a distillation to recover a higher alcohol product.
