Abstract

A method for preparing a catalyst that involves continuously supplying a first stream containing a solvent, one or more metal precursors, and one or more support materials, and a second stream containing at least one reducing agent and/or precipitating agent. The first and second streams are combined to form a combined stream. In one embodiment, the combined stream may be fed to a mixing vessel. In another embodiment, the streams are combined in a mixing vessel. After the streams are combined, one or more metal precursors is reduced or precipitated within the pores of the one or more support materials. Thereafter, solids are separated from the combined stream and processed to produce the supported metal, mixed-metal, metal oxide, or mixed-metal oxide catalyst. In another embodiment, ceramic or metallic monoliths may be coated with the catalytic material after the stream combination and before or after the solid separation and subsequent processing.
