Patent number: 8007750Abstract: A layered, three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides is disclosed. Methods of making and using the same are also provided. In one or more embodiments, the catalyst comprises three layers of catalytic material in conjunction with a carrier. A first layer comprises a platinum component on a first support; a second layer comprises a rhodium component on a second support; and a third layer comprises a palladium component and a third support. The palladium, rhodium, and/or platinum can independently be deposited on a support of high surface area refractory metal oxide, or of an oxygen storage component, or both.Type: GrantFiled: July 19, 2007Date of Patent: August 30, 2011Assignee: BASF CorporationInventors: Shau-Lin Franklin Chen, Jin Sakakibara, Tian Luo, Harold Rabinowitz

Patent number: 7749472Abstract: The present invention provides for novel poisoning-resistant catalysts used for automobile exhaust gas treatment systems. To alleviate the detrimental affects of engine oil and/or fuel additive poisoning the present invention provides for an overcoat layer comprising a porous refractory oxide and one or more base metal oxides, which is coated over one or more precious metal containing washcoat layers. The overcoat of the present invention prevents phosphorous as well as other poisoning deposits, from fouling and/or negatively interacting with the underlying precious metal containing washcoats. In an alternative embodiment, the present invention provides for the coating of the upstream end of a catalytic member by the overcoat layer, thereby creating an upstream poison capture zone.Type: GrantFiled: August 14, 2006Date of Patent: July 6, 2010Assignee: BASF CorporationInventors: Shau-Lin Franklin Chen, Knut Wassermann, Jin Sakakibara

Patent number: 7678347Abstract: The present invention discloses novel catalysts for treating automobile exhaust that have increased resistance to poisoning from oil- and/or fuel-derived additives. In the catalysts of this invention, the catalytic materials are not coated onto a front-end poison capture zone of the support that carries the catalytic layers. Since poisonous elements tend to deposit on the upstream end of the catalyst, such poisons do not inactivate any of the catalytic materials.Type: GrantFiled: July 15, 2005Date of Patent: March 16, 2010Assignee: BASF Catalysts LLCInventor: Shau-Lin Franklin Chen
