ABSTRACT:
The present invention provides a method of preparing a supported catalyst from a liquid catalyst system dispersed on a solid carrier. The method of this embodiment comprises freezing the liquid catalyst system in a non-reactive liquid to form a frozen catalyst system dispersed within the non-reactive liquid. The frozen catalyst system is then contacted with a solid carrier. Finally, the non-reactive liquid is removed to yield the supported catalyst. In another embodiment, a supported catalyst made by the methods of the present invention is provided.
