Japanese Patent JPH05503032

A

The invention relates to a process and to an apparatus for preparing a heterogeneous catalyst having at least one catalytically active species bound to the surface of a support material. According to the process, the surface of the support is first pretreated. A catalyst reagent containing the catalytically active species or its precursor is vaporized and the vapor is routed into a reaction chamber where it is brought to interact with the support material. The catalyst reagent not bound to the support is withdrawn from the reaction chamber in gaseous form. If necessary, the species bound to the support is posttreated in order to convert it into a catalytically active form. According to the invention, the amount of catalyst reagent brought into the reaction chamber is at least equal to, preferably in excess of the number of available binding sites on the surface. The temperature of the support of kept higher than the condensation temperature of the vapor and at the same time at a sufficiently high level to attain the thermal activation energy needed for forming bonds between the active species and the support. By binding the catalytically active species in this way to the support it is possible to provide a heterogeneous catalyst having a high activity even at small amounts of the active species.
