ABSTRACT:
The present invention is directed to a process for preparing a catalyst which comprises combining catalyst components or precursors thereof in an aqueous medium to form a catalyst precursor mixture, feeding the mixture to a shaping apparatus, and shaping the mixture to form particles wherein just before the shaping step the mixture is destabilized. It was found that with this process catalysts can be prepared which have both a good attrition resistance and a high accessibility. The invention further relates to catalysts obtainable by this process.
