Abstract:
A process for producing a heterogeneous massive catalyst wherein the catalyst comprises at least one catalytically active component in the form of solid particles and at least one catalytically inert component in the form of solid particles wherein the components are dispersed in one another and wherein the inert component has a mean particle diameter greater than the mean particle diameter of the catalytically active component, which comprises the steps of:(a) producing in a suspension liquid at least one suspension of solid particles of the catalytically active component and in a suspension liquid at least one suspension of solid particles of the catalytically inert component;(b) combining the suspension of the solid particles of the catalytically active component in the suspension liquid and the suspension of the solid particles of the catalytically inert component in the suspension liquid and subjecting the combined suspensions to ultrasound; and(c) separating the suspension liquid from the solid particles in the combined suspension, said solid particles forming the heterogeneous massive catalyst.
