Publication number: 20140322114Abstract: A three-way catalyst including a mixture of nickel and copper is provided for reducing carbon monoxide, hydrocarbon emissions, and nitrogen oxides from vehicle engine exhausts. The catalyst is impregnated onto a carrier substrate which is non-reactive with nickel and copper. When used in a vehicle exhaust gas treatment system, the nickel-copper catalyst provides improved efficiency in reducing CO, HC, and NOx emissions over the use of conventional three-way-catalysts and provides enhanced oxygen storage capacity (OSC) and water-gas-shift (WGS) functions.Type: ApplicationFiled: April 29, 2013Publication date: October 30, 2014Applicant: Ford Global Technologies, Inc.Inventors: Hungwen Jen, Eva Thanasiu, Jeffrey Scott Hepburn

Patent number: 8865120Abstract: The present invention is directed to a process for the production of ion-exchanged (metal-doped, metal-exchanged) Zeolites and Zeotypes, In particular, the method applied uses a sublimation step to incorporate the ion within the channels of the Zeolitic material. Hence, according to this dry procedure no solvent is involved which obviates certain drawbacks connected with wet exchange processes known in the art.Type: GrantFiled: December 8, 2011Date of Patent: October 21, 2014Assignee: Umicore AG & Co., KGInventors: Fei Wen, Barry W.

Patent number: 8846559Abstract: A catalyst and method of forming a catalyst for use in aromatic alkylation involves treating a zeolite, which may be a ZSM-5 zeolite, with a phosphorus-containing compound. The phosphorus-treated zeolite is combined with a binder material. The bound phosphorus-treated zeolite is treated with an aqueous solution of a hydrogenating metal compound by contacting the bound phosphorus-treated zeolite with the aqueous solution and separating the aqueous solution from the bound phosphorus-treated zeolite to form a hydrogenating-metal-containing zeolite catalyst. The catalyst may be used in preparing an alkyl aromatic product by contacting a hydrogenating-metal-containing zeolite catalyst with an aromatic alkylation feed of an aromatic compound and an alkylating agent under reaction conditions suitable for aromatic alkylation.Type: GrantFiled: November 3, 2008Date of Patent: September 30, 2014Assignee: Saudi Basic Industries CorporationInventors: Ashim Kumar Ghosh, Neeta Kulkarni
