Title (EN) EPOXIDATION PROCESS
(FR) PROCÉDÉ D'ÉPOXYDATION
Abstract:
(EN) A method is provided for improving the performance of a silver-based epoxidation catalyst comprising a carrier. The carrier includes at least 80 percent alpha alumina and has a pore volume from 0.3 mL/g to 1.2 mL/g, a surface area from 0.3 m2/g to 3.0 m2/g, and a pore architecture that provides at least one of a tortuosity of 7 or less, a constriction of 4 or less and a permeability of 30 mdarcys or greater. A catalytic amount of silver and a promoting amount of one or more promoters is disposed on and/or in said carrier. The method further includes the steps of initiating an epoxidation reaction by reacting a feed gas composition containing ethylene and oxygen present in a ratio of from about 3.5:1 to about 12:1, in the presence of the silver-based epoxidation catalyst at a temperature of about 200°C to about 230°C, and subsequently increasing the temperature either stepwise or continuously.
(FR) L'invention concerne un procédé permettant d'améliorer la performance d'un catalyseur d'époxydation à base d'argent comprenant un support. Le support comprend au moins 80 pour cent d'alpha-alumine et possède un volume de pore allant de 0,3 mL/g à 1,2 mL/g, une surface spécifique allant de 0,3 m2/g à 3,0 m2/g, et une architecture de pore qui fournit au moins une propriété parmi une tortuosité de 7 ou moins, une constriction de 4 ou moins et une perméabilité de 30 mdarcys ou plus. Une quantité catalytique d'argent et une quantité promotrice d'un ou plusieurs promoteurs sont disposées sur et/ou dans ledit support. Le procédé comprend en outre les étapes consistant à amorcer une réaction d'époxydation en faisant réagir une composition de gaz d'alimentation contenant de l'éthylène et de l'oxygène, présents dans un rapport allant d'environ 3,5:1 à environ 12:1, en présence du catalyseur d'époxydation à base d'argent à une température d'environ 200 °C à environ 230 °C, et augmenter ultérieurement la température soit par paliers soit de façon continue.
