Vanadia-Titania Xerogel Catalysts for Ammoxidation and Preparing Method of the same

摘要

The present invention is a hydrocarbon compound of ammonia, a bar used for producing a nitrile compound in cancer oxy reaction of oxygen and reaction vanadia-titania Jiro relates to a gel catalyst, its manufacturing method and reactive. Vanadia of the invention Jiro titania gel catalyst, nano-particles and the size of the gel having a Giro networked pore structures, vanadia and titania consists of 1 to 10% by weight of the total catalyst by weight of the content of the bar Nadia , preferably 3 to 5% by weight to the content. In addition, the invention of the vanadia-titania catalyst may Jiro gel further contains chromium, antimony, tin, iron, bismuth, molybdenum, and at least one selected from the group consisting of metal oxide, or of potassium. Vanadia according to the invention - when titania Jiro gel catalyst, was used in cancer oxy reaction of hydrocarbon compounds, lower vanadia greatly improve the yield and selectivity of the conversion of a hydrocarbon compound and a nitrile compound in a wide reaction temperature range in content which can be a catalyst for cost-effective. ; Cancer oxy reaction, catalyst, m- xylene, Giro gel, vanadia, titania
