摘要： A process and catalyst for the direct oxidation of an olefin having three or more carbon atoms, such as propylene, by oxygen to 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 comprises gold on a support of titanium dispersed on silica. The titanium phase is disorganized and substantially free of crystalline titanium dioxide, as determined by analytical methods, such as, high resolution transmission electron microscopy and Raman spectroscopy. Selectivity to olefin oxide is high at good conversions of the olefin. The time between catalyst regenerations is long, and the catalyst is readily regenerated.

摘要： A process and catalyst for the direct oxidation of an olefin having three or more carbon atoms, such as propylene, by oxygen to the corresponding olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen under reaction conditions in the presence of hydrogen and in the presence of a catalyst. The catalyst comprises gold on a titanosilicate, preferably a microporous or mesoporous titanosilicate, such as, TS-1, TS-2, Ti-beta, Ti-ZSM-48, or Ti-MCM-41. Selectivity to the olefin oxide is high at good conversions of the olefin. The catalyst is readily regenerated, and the time between catalyst regenerations is long.

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.
