A Hydrogenation Catalyst, Its Method of Preparation and Use |
摘要 |
A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a median pore size of at least about 10 nm with a silylating agent to form an at least partially coated silica support, calcining said coated silica support to form a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support, and optionally contacting the treated silica support with an optional 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. |

1. A method for the preparation of a silica-supported noble metal hydrogenation catalyst comprising the steps of:
(a) contacting a silica support having a median pore size of at least about 10 nm with a silylating agent to coat at least part of the silica support to produce a coated silica support; (b) calcining the coated silica support obtained in step (a) to produce a treated silica support; and (c) depositing a noble metal on the treated silica support obtained in step (b) to produce a noble metal-containing silica support. |
