Patent number: 7078004Abstract: The present invention relates to a method and article for treating a diesel engine exhaust stream. The stream is contacted with an upstream catalytic composition having a cerium component and/or a zeolite component to reduce the quantity and amount of the particulate matter in the exhaust stream. The stream passes from the upstream catalytic composition to a particulate filter located downstream from the upstream catalytic composition.Type: GrantFiled: January 10, 2003Date of Patent: July 18, 2006Assignee: Engelhard CorporationInventors: Kenneth E. Voss, Joseph C. Dettling, Stanley Roth, Ramesh Kakwani, Yiu Kwan Lui, Alexander Gorel, Gary W. Rice

Patent number: 6422008Abstract: Methods and apparatus for reducing the TPM level of a diesel engine exhaust stream by providing a suitable oxidation catalyst into the exhaust train. The oxidation catalyst may be incorporated into a thermal insulative coating on the inner surface of the exhaust train, particularly the exhaust manifold and exhaust pipes prior to the turbocharger. Alternatively, when the exhaust train includes a turbocharger, the catalyst can be in a separate monolithic unit between the engine and the turbocharger. The system may also include an improved diesel oxidation catalyst unit having a metal monolithic substrate. The oxidation catalyst can also be incorporated into a thermal insulative coating inside the cylinders, particularly on non-rubbing surfaces such as The invention also includes the use of a protective mullite top coat on the thermal coating. A further embodiment is the use of a stainless steel bond coat to bind the thermal coating to a metallic substrate, particularly an aluminum substrate.Type: GrantFiled: April 16, 2001Date of Patent: July 23, 2002Assignee: Engelhard CorporationInventors: Kenneth E. Voss, Timothy D. Wildman, Michael G. Norris, Gary W. Rice

Patent number: 4575609Abstract: A concentric micro-nebulizer and method for introducing liquid samples into a plasma established in a plasma torch including a first tube connected to a source of plasma gas. The concentric micro-nebulizer has inner and outer concentric tubes extending upwardly within the torch for connection to a source of nebulizer gas and to a source of liquid solvent and to a source of sample liquid. The inner tube is connected to the source of liquid solvent and to the source of sample liquid and the outer tube is connected to the source of nebulizer gas. The outer tube has an orifice positioned slightly below the plasma when it is established, with the inner and outer tubes forming an annulus therebetween with the annular spacing between the tubes at said orifice being less than about 0.05 mm. The dead volume of the inner tube is less than about 5 microliters.Type: GrantFiled: March 6, 1984Date of Patent: March 11, 1986Assignee: The United States of America as represented by the United States Department of EnergyInventors: Velmer A.
