Abstract: The present invention addresses at least four different aspects relating to catalyst structure, methods of making those catalysts and methods of using those catalysts for making alkenyl alkanoates. Separately or together in combination, the various aspects of the invention are directed at improving the production of alkenyl alkanoates and VA in particular, including reduction of by-products and improved production efficiency. A first aspect of the present invention pertains to a unique palladium/gold catalyst or pre-catalyst (optionally calcined) that includes rhodium or another metal. A second aspect pertains to a palladium/gold catalyst or pre­catalyst that is based on a layered support material where one layer of the support material is substantially free of catalytic components. A third aspect pertains to a palladium/gold catalyst or pre-catalyst on a zirconia containing support material. A fourth aspect pertains to a palladium/gold catalyst or pre-catalyst that is produced from substantially chloride free catalytic components.

Abstract: Cut filler compositions, cigarette paper, cigarette filters, cigarettes, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of a catalyst capable converting carbon monoxide to carbon dioxide. The catalyst comprises nanoscale metal and/or metal oxide particles supported on high surface area support particles. The catalyst can be prepared by combining a metal precursor solution with high surface area support particles to form a mixture, or by combining a metal precursor solution with a colloidal solution to form a mixture, and then heat treating the mixture.

Abstract: The present development is a transition metal-based catalyst having a high surface area, a smooth, homogeneous surface morphology, an essentially uniform distribution of cobalt throughout the support, and a small metal crystallite size. The high surface area transition metal-based catalysts of the present invention are prepared in a non-acidic solution at a pH greater than about 7.0, and starting with a non-acidic transition metal complex. The resulting product is a catalyst with a uniform distribution of metal throughout the catalyst particles, with a smooth and homogeneous surface morphology, and with slow crystallite growth upon heating.
