20080247929HIGH ACTIVITY TITANIA SUPPORTED METAL OXIDE DeNOx CATALYSTS - The present invention is directed to high activity titanium oxide DeNOx catalysts. In preferred embodinents, by depositing vanadium oxide on a titania supported metal oxide such as tungsten oxide, an improved catalyst may be generated. This catalyst may be used in the treatment of exhaust from sources such as automobiles and industrial plants.10-09-2008
20080279740DeNOx catalyst preparation method - A catalyst comprising iron and a titanium-zirconium mixed oxide gel, and a process for preparing the catalyst are disclosed. The process comprises combining an iron compound and a titanium-zirconium mixed oxide gel in water to form an iron-titanium-zirconium mixed oxide, and then removing water to produce the catalyst. The catalyst is particularly effective for DeNO11-13-2008
20090062111Transparent, Stable Titanium Dioxide Sols - A method of preparing stable, transparent photocatalytic titanium dioxide sots is disclosed which involves thermal treatment of a suspension of amorphous titanium dioxide in the presence of certain alpha-hydroxy acids. The sots comprise titanium dioxide particles in the anatase form having a crystallite size less than about 10 nm and exhibit excellent stability and transparency at basic, neutral, and acid pH.03-05-2009
20090192323Spray-dried transition metal zeolite and its use - A catalyst comprising a spray-dried transition metal zeolite and a noble metal is disclosed. The spray-dried transition metal zeolite comprises a transition metal zeolite and a binder. At least 50 wt. % of the binder is titania. The catalyst is used in a process to produce an epoxide by reacting an olefin, hydrogen, and oxygen. The catalyst is easy to filter from a slurry and produces a reduced level of hydrogenation products.07-30-2009
20090209665COLLOIDAL TITANIUM DIOXIDE SOLS - Stable, translucent or transparent titanium dioxide sols comprising amorphous titanium dioxide and an organic peptizing agent are provided that are useful in particulate binding applications. Also provided are methods for preparing the inventive sols. The inventive sols are prepared from titanium dioxide precursors including organotitanium compounds and water-soluble titanium salts that are treated to precipitate amorphous titanium dioxide. The amorphous titanium dioxide is re-dispersed and peptized to form a translucent or transparent mixture. The inventive sols are stable for an extended period of time.08-20-2009
20090324472NANOCOMPOSITE PARTICLE AND PROCESS OF PREPARING THE SAME - A nanocomposite particle, its use as a catalyst, and a method of making it are disclosed. The nanocomposite particle comprises titanium dioxide nanoparticles, metal oxide nanoparticles, and a surface stabilizer. The metal oxide nanoparticles are formed hydrothermally in the presence of the titanium dioxide nanoparticles. The nanocomposite particle is an effective catalyst support, particularly for DeNO12-31-2009
20090325787NANOCOMPOSITE PARTICLE AND PROCESS OF PREPARING THE SAME - A nanocomposite particle, its use as a catalyst, and a method of making it are disclosed.
