Abstract: The present invention relates to a method of preparing catalyst bodies, in particular catalyst flakes, in particular for high throughput experimentation, wherein the method comprises the steps of: a) preparing a mixture comprising catalyst components; b) distributing the mixture on a substantially flat surface; c) compressing the mixture into a substantially flat plate of uniform thickness by applying onto the mixture, obtained after step b) a pressure of at least 50 kg/cm2 d) breaking the plate into a particulate. The invention further relates to catalyst bodies obtainable by the method and to the use of the catalyst bodies in high throughput experimentation.
