Abstract

A process for producing ceramic, ceramic-metal or metal catalyst supports or catalysts with open, interconnecting pores. The process forming a dense agglomeration of spherical, cylindrical or similar bodies of generally uniform size. These bodies are connected together at their mutual contact points, thereby producing a framework corresponding generally to the macropores and pore interconnections of the finished material in terms of size and arrangement. The framework is then filled with a suspension containing as solid components the catalyst support material and/or the catalyst material. The suspension can also contain a binding agent. The framework is subsequently dissolved away after at least the partial hardening of the cast mass without destroying the structure produced during hardening.
