Hydrogenation catalyst and process to form 1,4-butanediol.

摘要

The invention relates to a method of producing 1.4 - BUTANE DIOL, which is catalytically hydrogenating a hydrogenatable precursor thereof CONTACT gas containing hydrogen and a hydrogenation catalyst comprising at least one Group VIII metal periodic Table and at least one element selected from rhenium, tungsten and molybdenum, deposited on a carbon support. SUCH carbon support is contacted with an agent OXIDANTE selected from the group consisting of nitric acid hydrogen peroxide, SODIUM HYPOCHLORITE, Ammonium persulfate and perchloric acid, before deposition of these metals. Also it provided the carbon support DESCRIBED.
