  • Patent number: 6680279
    Abstract: A method of dispersing nanosized catalyst particles on the surface of larger catalyst carrier particles is disclosed. The coating process is done dry and yields high effective surface area of nanosized catalyst particles coated on the surface of catalyst carrier particles. In this process, nanosized catalyst particles and catalyst carriers are mechanically mixed in a high velocity and impact force environment to which catalyst particles are embedded, or filmed, on the surface of catalyst carrier particles without using water or any other additional chemicals. The catalyst composite structure produced comprises better coating uniformity of the catalyst particle on its catalyst carrier. The catalyst particle/catalyst carrier composite produced can be applied to a support structure, such as a monolith as readily used in automotive or other applications.

  • Patent number: 6287527
    Abstract: Exhaust emission control catalysts capable of efficiently removing nitrogen oxide in exhaust containing a large amount of oxygen emitted from a diesel engine and the like and reducing the generation of particulate matter in the exhaust under high temperature conditions, and a method for controlling the emission of exhaust using the exhaust emission control catalysts. The exhaust emission control catalysts contain copper, praseodymium, and yttrium. The method for controlling the emission of exhaust purifies exhaust containing hydrocarbon and nitrogen oxide in a mole ratio (hydrocarbon/nitrogen oxide) within a range of 0.5 to 30 by bringing the exhaust into contact with the exhaust emission control catalysts. It is possible to efficiently remove nitrogen oxide in the exhaust by reduction while suppressing the oxidation of sulfur dioxide in the exhaust.

  • Publication number: 20010016184
    Abstract: A system for treating the exhaust of an industrial process or combustion source to capture gaseous sulfur compounds which includes contacting the exhaust containing gaseous sulfur compounds with a system of: (1) a structured support coated with for example a monolith (2) a ceramic oxide containing for example TiO2 (3) a precious metal component for example Pt and optionally (4) a modifier such as Cu. The system captures the gaseous sulfur compounds. Gaseous sulfur compounds are then driven off in higher concentrations in a separate isolated lower flow stream in higher concentrations which are easier to process to less noxious or useful sulfur materials, and the catalyst/sorber regenerated. The system also removes carbon dioxide by the oxidation of the carbon monoxide to carbon dioxide.

  • Patent number: 6274533
    Abstract: Novel sorbent systems for the desulfurization of cracked-gasoline are provided which are comprised of a bimetallic promotor on a particulate support such as that formed of zinc oxide and an inorganic or organic carrier. Such bimetallic promoters are formed of at least two metals of the group consisting of nickel, cobalt, iron, manganese, copper, zinc, molybdenum, tungsten, silver, tin, antimony and vanadium with the valence of same being reduced, preferably to zero. Processes for the production of such sorbents are provided wherein the sorbent is prepared from impregnated particulate supports or admixed to the support composite prior to particulation, drying, and calcination. Further disclosed is the use of such novel sorbents in the desulfurization of cracked-gasoline whereby there is achieved not only removal of sulfur but also an increase in the olefin retention in the desulfurized product. Such sorbents can also be utilized for the treatment of other sulfur-containing streams such as diesel fuels.

  • Patent number: 6165932
    Abstract: The invention is a sol-gel processed metal-aluminum based oxide material useful as a catalyst including a NOx trapping catalyst. It is made from alkoxides comprising heterometallic alkoxides. The metal is transition metal, one or both of alkali metal and alkaline earth metal, and optionally also a lanthanide. Then invention is also a method of treating lean-burn internal combustion engine exhaust gas with this material, without any precious metal included with the material, in the exhaust gas system. The method comprises locating the NOx trap in the system where the NOx trap absorbs nitrogen oxides during lean cycle operation and desorbs the nitrogen oxides when the concentration of the oxygen in the exhaust gas is lowered as during a rich or stoichiometric cycle.
