Latest Patents
One of his latest patents is a process for preparing an oxidation catalyst. This invention provides a catalyst composition suitable for the gas phase oxidation, ammoxidation, and oxidative dehydrogenation of olefins to unsaturated aldehydes, unsaturated nitriles, and dienes. The catalyst composition comprises a solid solution of Fe, Sb, and Ti oxides with a rutile type crystal structure, present in an amount of at least 80 wt.%. The empirical formula for this composition is Fe.sub.x Sb.sub.y Ti.sub.z O.sub.w, where specific ranges for x, y, and z are defined. The preparation involves co-precipitating metal oxides from solutions of corresponding metal salts, followed by calcination at temperatures between 600°C and 1000°C.
Another significant patent by Villa is a catalyst for the oxidation of methanol to formaldehyde. This catalyst is prepared by mixing an aqueous molybdate solution with an aqueous solution of a ferric salt, maintaining a specific Mo/Fe atomic ratio. The process includes heating the suspension, washing the precipitate, and drying it to reduce water content. The final catalyst consists of granules of crystalline iron molybdate and molybdenum trioxide, with specific interactions with bismuth oxide.
