Abstract: Disclosed are a grain boundary and surface-loaded noble metal catalyst, a preparation method and an application thereof. The noble metal is dispersed at the grain boundary and surface of alumina and/or a rare earth manganese-zirconium composite oxide to form a multiphase interface, which achieves the following beneficial technical effects: firstly, the multiphase interface has a larger steric hindrance and a stronger anchoring effect, which can inhibit the migration, agglomeration, and growth of the noble metal at high temperatures, increase the high-temperature stability and catalytic performance of the noble metal, and reduce the usage of the noble metal; secondly, the multiphase interface exhibits a synergistic catalytic effect, which can reduce the activation energy of lattice oxygen and increase the quantity of active oxygen, thereby enhancing the NO oxidation and low-temperature catalytic activity.

Abstract: The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source. Catalysts that may be produced using this improved process include but are not limited to catlaysts that promote CO hydrogenation, reforming catalysts, Fischer Tropsch Catalysts, Greyrock GreyCat™ catalysts, catalysts that homologate methanol, catalysts that promote hydrogenation of carbon compounds, and other catalysts used in industry.

Abstract: Methods for manufacturing catalyst particles comprising one or more active metal components are provided. The particles are a composite of a granulating agent or binder material such as an inorganic oxide, and an ultra-stable Y (hereafter “USY”) zeolite in which some of the aluminum atoms in the framework are substituted with zirconium atoms and/or titanium atoms and/or hafnium atoms. The one or more active phase components are incorporated prior to mixing the binder with the post-framework modified USY zeolite, extruding the resulting composite mixture, and forming the catalyst particles. The one or more active phase components are incorporated in the post-framework modified USY zeolite prior to forming the catalyst particles.
