Claim:
1. A process for producing coated catalysts, comprising: a) providing a composition containing a liquid and at least one of a catalytically active material or a precursor thereof in a stock vessel; b) providing a support material in a vessel which is rotatable about a longitudinal axis; c) transporting the composition from the stock vessel through a first conduit to a spray nozzle; d) transporting a propellant fluid through a second conduit to the spray nozzle; e) atomizing the composition and propellant fluid in the nozzle to produce an aerosol which flows into the vessel and impregnates the support material present therein; f) heating the vessel so that the liquid present in the aerosol evaporates from the support material and the support material which has been treated with catalytically active material and/or a precursor thereof is dried; and g) at least one of discharging or extracting the vaporized liquid from the vessel.
