摘要： A process and catalysts 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 under reaction conditions with oxygen in the presence of hydrogen and a catalyst. The catalyst contains silver and titanium, optionally gold, and optionally, at least one promoter element selected from Group 1, Group 2, zinc, cadmium, the lanthanide rare earths, and the actinide elements. Suitable supports include titanium dioxide, titanium dioxide on silica, titanosilicates, promoter metal titanates, titanium dispersed on silica and promoter metal silicates.

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 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 zeolite-based ethylbenzene process which is suitable for retrofitting aluminum chloride-based ethylbenzene plants. The process involves alkylating benzene with ethylene in an alkylation zone in the presence of zeolite beta or Y or an MCM zeolite so as to produce an alkylation product mixture containing benzene, ethylbenzene, and polyethylbenzenes which can be separated in the aromatics recovery (distillation) stage of an aluminum chloride-based plant. The polyethylbenzenes are subsequently contacted with benzene in a transalkylation zone using zeolite beta or mordenite or Y so as to produce a transalkylation product mixture which is also separable in the aromatics recovery stage of an aluminum chloride-based plant.
