摘要： A method of increasing the lifetime of a hydro-oxidation catalyst comprising, preferably, gold, silver, or mixtures thereof, and optionally one or more promoters, on a titanium-containing support, such as a titanosilicate or titanium dispersed on silica. The method of the invention involves contacting the catalyst support with a hydroxy-functionalized organosilicon compound, a carboxy-functionalized organosilicon compound, or a mixture of hydroxy- and carboxy-functionalized organosilicon compounds, such as, sodium methyl siliconate or (2-carboxypropyl)tetramethyldisiloxane. The contacting is preferably conducted during deposition of the catalytic metal(s) and optional promoters(s) onto the support. A catalyst composition and hydro-oxidation process utilizing the silicon-treated catalyst support are also claimed.

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.

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.
