20120015801 | PROCESS FOR PREPARATION OF A ZEOLITE-BASED CATALYST - Disclosed is a method for preparing a zeolite-based catalyst for application on a substrate. The method consists of the steps of: preparing a chemical composition comprising tin oxide, zirconium oxide, cerium oxide, and lanthanum oxide; combining the composition with a catalyst comprising a two-phase hydrocarbon NO | 01-19-2012 |
20110120087 | Apparatus with Catalyst for the Reduction of Nitrogen Dioxide (NO2) to Nitric Oxide (NO) by Chemical Means in a Diesel Catalytic Support - In setting tighter emissions standards for nitrogen oxides, legislative bodies limit the amount of nitrogen dioxide (NO | 05-26-2011 |
20110113762 | Use Of Powder Coated Nickel Foam As A Resistor To Increase The Temperature of Catalytic Converter Devices With The Use Of Electricity - The disclosed invention relates to the optimization of catalytic reactions in diesel engines. A powder-coated nickel or other metallic foam is used as both the substrate and a resistor in a catalytic converter. The disclosed method uses a closed-loop system to heat the metallic foam with electric current to heat the diesel exhaust and thereby optimize the temperature at which the catalytic reaction occurs. The disclosed apparatus comprises a metallic foam substrate with a catalytic coating. The substrate is heated with electrical current to optimize the catalytic reaction. A variety of washcoats and/or catalysts may be used to coat the metallic foam substrate and the optimal temperature will depend on the catalyst used. | 05-19-2011 |
20100199649 | APPARATUS FOR REMOVING SOOT FROM DIESEL ENGINE EXHAUST STREAMS AT TEMPERATURES AT OR BELOW 150.degree. C - An apparatus for removing soot from diesel engine exhaust streams at temperatures below 150° C. is provided. Although the use of particulate filters for removing carbonaceous soot from such exhaust streams is known, such systems are either active or operate under high temperatures, i.e. in excess of 300° C. The claimed apparatus includes a flow through support device composed of ceramic, such as cordierite or silicon carbide, or a primarily nonferrous metal or stainless steel and coated with an oxide formation comprising hematite and bixbyite in a ratio from 1:1 to 9:1. The claimed apparatus can also include a diesel particulate filter coated with a coating comprising tin, aluminum and zirconium oxides prepared by a co-precipitation process and thereafter coated with platinum or other precious metal. | 08-12-2010 |
