Summary: | A multi-functional composite catalyst includes a catalyst support material, a preformed catalyst material at least partially secured in the catalyst support, and at least one catalytically active compound supported by the catalyst support, the preformed catalyst material, or both. The catalyst support material may include fumed silica, alumina, fumed alumina, fumed titania, or combinations of these. A catalytic activity of the catalytically active compound may be different than a catalytic activity of the preformed catalyst material. The composite catalyst may be catalyst for producing propenefrom 2-butene and may include a zeolite as the preformed catalyst material and a metal oxide, such as tungsten oxide, as the catalytically active material. A method of making the composite catalyst may include aerosolizing a catalyst precursor mixture that includes a preformed catalyst material, catalyst support precursor, and catalytically active compound precursor, and drying the aerosolized catalyst precursor mixture. |
