Patent

CA 2646722

A process for manufacturing a porous ceramic body- using a pore former containing potassium is disclosed. The pore former is treated to reduce the concentration of the potassium prior to forming a mixture with a heat sinterable material, such as alumina. Porous ceramic material, particularly carriers for catalyst used in epoxidation reactions, can be manufactured using the process disclosed herein.

L'invention concerne un procédé de fabrication d'un corps céramique poreux en utilisant un formateur de pores contenant du potassium. Le formateur de pores est traité afin de réduire la concentration en potassium avant de former un mélange avec un matériau frittable thermiquement, tel que l'alumine. L'invention concerne également un matériau céramique poreux, notamment des supports pour catalyseur utilisés dans des réactions d'époxydation, pouvant être fabriqué en utilisant le procédé selon l'invention.
