  • Catalyst or membrane precursor systems, catalyst or membrane systems, and method of preparing such systems
    Patent number: 5472927
    Abstract: A catalyst or membrane system comprising a thermostable, high porous layer applied on a less porous or nonporous support layer, in particular on the inner surface of a monolith or sintered metal body, in the inner pores of .alpha.-alumina, of a carbon carrrier or on the surface of a ceramic membrane. The catalyst system can be prepared by spreading a solution of a metallo-organic compound on the inner surface of the support layer and then converting the organometallic compound into the oxide. In the high-porous layer thus obtained, a catalytically active material can be applied in the conventional manner.
