摘要： A process and catalyst for the hydro-oxidation of an olefin having three or more carbon atoms, such as propylene, to form an olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen under reaction conditions in the presence of hydrogen and a catalyst. The catalyst contains oxidized gold dispersed on a titanium-containing support, preferably, a support having a plurality of titanium coordination environments, for example, titanium grafted onto a titanosilicate. Selectivity to olefin oxide is high at good conversion of the olefin. The catalyst uses hydrogen efficiently and exhibits a long lifetime.

摘要： A process of preparing a catalyst comprising gold on a titanium-containing support. The method involves impregnating a support with a gold compound, a reducing agent, and optionally a promoter metal, wherein the reducing agent and/or the support contains titanium, and optionally heating the impregnated support. The catalyst is useful in the hydro-oxidation of olefins, such as propylene, with oxygen in the presence of hydrogen to olefin oxides, such as propylene oxide.
