A carrier for a catalyst useful for the epoxidation of an olefin which comprises an inert, refractory solid carrier is provided. The carrier has no or little absolute volume from small pores, of less than 1 micrometer, and large pores, of above 5 micrometer. By "no or little absolute volume from small pores of less than 1 micron" it is meant that the pore volume of such pores is less than 0.20 ml/g. By "no or little absolute volume from large pores of above 5 micron" it is meant that the pore volume of such pores is less than 0.20 ml/g. The invention further provides a catalyst useful for the epoxidation of an olefin supported on such a carrier and a process for the oxidation of an olefin, especially ethylene, to an olefin oxide, especially ethylene oxide.
L'invention porte sur un support pour un catalyseur utile pour l'époxydation d'une oléfine, qui comprend un support solide réfractaire inerte. Le support présente un volume absolu faible ou nul provenant de petits pores, inférieurs à 1 micromètre, et de pores de grande dimension, supérieurs à 5 micromètres. Par = volume absolu faible ou nul provenant de petits pores inférieurs à 1 micron =, on entend que le volume des pores de tels pores est inférieur à 0,20 ml/g. Par = volume absolu faible ou nul provenant de pores de grande dimension supérieurs à 5 microns =, on entend que levolume des pores de tels pores est inférieur à 0,20 ml/g. L'invention porte également sur un catalyseur utile pour l'époxydation d'une oléfine supportée sur un tel support, et sur un procédé d'oxydation d'une oléfine, en particulier l'éthylène, en un oxyde d'oléfine, en particulier l'oxyde d'éthylène.
