摘要： The present disclosure provides an improved method for preparing a carbon supported Pt—Re catalyst (Pt—Re/C) using a soluble non-chlorinated Pt material as a Pt source. The catalysts prepared by the methods described herein can achieve the same level of catalytic capacity as that of the catalysts prepared by the conventional method using chlorinated Pt precursors.

摘要： Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and either a supported chromium (VI) catalyst or a supported chromium (II) catalyst are contacted, optionally with UV-visible light irradiation, followed by exposure to an oxidizing atmosphere and then hydrolysis to form a reaction product containing the alcohol compound and/or the carbonyl compound. The presence of oxygen significant increases the amount of alcohol/carbonyl product formed, as well as the formation of oxygenated dimers and trimers of certain hydrocarbon reactants.

摘要： The invention relates to catalysts comprising palladium on a support in which the palladium is distributed in the support as an eggshell. The palladium surface area is at least 150 m2/gPd. A method for manufacturing such catalysts involves impregnating a support with an impregnation solution comprising palladium ions and citrate ions, followed by drying the resulting product. Also described is an impregnation solution comprising palladium ions, citric and/or citrate ions, and acetic acid, which is suitable for manufacturing the catalysts described.
