Patent

CA 2571179

A process is provided for the epoxidation of an olefin comprising the steps of: contacting a feed comprising an olefin and oxygen with a catalyst comprising a silver component and a high-selectivity dopant deposited on a fluoride-mineralized carrier; and producing a product mix comprising an olefin oxide, wherein the concentration of carbon dioxide in the feed is less than 2 mole-%, relative to the total feed.

L'invention concerne un procédé d'époxydation d'une oléfine, qui consiste à placer une charge d'alimentation comprenant une oléfine et de l'oxygène au contact d'un catalyseur comprenant un constituant argent et un dopant à grande sélectivité déposé sur un support minéralisé au fluor. Le procédé consiste ensuite à produire un mélange comprenant un oxyde d'oléfine, la concentration du dioxyde de carbone dans la charge d'alimentation étant inférieure à 2 % en mole relativement à la charge d'alimentation totale.
