Patent number: 9346019Abstract: The present invention relates to a diesel particle filter which has a coating active in oxidation catalysis and which is characterized in that said diesel particle filter comprises a material zone which removes platinum traces contained in the exhaust-gas flow, and to the use of said diesel particle filter in the purification of exhaust gases of diesel engines.Type: GrantFiled: April 17, 2013Date of Patent: May 24, 2016Assignee: Umicore AG & CO. KGInventors: Marcus Pfeifer, Michael Schiffer, Franz Dornhaus, Stephan Basso, Frank-Walter Schuetze

Patent number: 9347354Abstract: An SCR-catalytically active diesel particle filter having a ceramic wall flow filter substrate with inflow channels, outflow channels, walls separating the inflow and outflow channels, and two coatings. The first coating is applied in inflow channels, is composed of high-melting point materials, and closes the inflow sides of pores in walls connecting the inflow channels and outflow channels to soot particles without preventing passage of gaseous exhaust gas constituents. The second coating is within the walls between inflow channels and outflow channels, and effectively catalyzes the selective reduction of nitrogen oxides when in the presence of a reducing agent. The particle filter displays excellent banking-up pressure properties combined with high filtration efficiency and good regeneration properties; and displays good aging stability of NOx conversion activity.Type: GrantFiled: March 30, 2011Date of Patent: May 24, 2016Assignee: UMICORE AG & CO. KGInventors: Marcus Pfeifer, Stephan Basso, Franz Dornhaus

Publication number: 20130004391Abstract: A diesel particle filter which comprises a ceramic wall flow filter substrate and two coatings is described. The first coating which is applied in the inflow channels and is composed of high-melting materials has such a nature that it closes the inflow channels and pores in the wall connecting the inflow channels and outflow channels to soot particles on the inflow side without preventing passage of the gaseous exhaust gas constituents. The second coating is introduced into the wall between inflow channels and outflow channels and is of such a nature that it can effectively catalyze the selective reduction of nitrogen oxides by means of a reducing agent. The resulting component is an SCR-catalytically active particle filter and displays excellent banking-up pressure properties combined with high filtration efficiency and good regeneration properties. Furthermore, the component displays good aging stability of the NOx conversion activity.Type: ApplicationFiled: March 30, 2011Publication date: January 3, 2013Applicant: UMICORE AG & CO.

Patent number: 7179764Abstract: The invention relates to a composite formed of a zeolite (such as ZSM-5 zeolite, ?-zeolite and silicalite) deposited on a rigid support, wherein the rigid support comprises silicon carbide (SiC) with a specific surface area BET of at least 5 m2/g. Preferably, the support is a ?-SiC foam with a specific area of between 10 and 500 m2/g. This composite may be used as a catalyst and/or a catalyst support for chemical reactions in a gas or liquid medium. For example materials of the present invention are useful for example, in connection with cracking, acylation, alkylation and/or isomerization of hydrocarbons.Type: GrantFiled: January 16, 2003Date of Patent: February 20, 2007Assignees: SICAT, Centre National de la Recherche Scientifique, Universite Louis Pasteur de StrasbourgInventors: Stephan Basso, Jean-Philippe Tessonnier, Cuong Pham-Huu, Marc J. Ledoux, Gauthier Wine

Patent number: 7067455Abstract: Catalysts and methods useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) comprise at least one base metal and copper with an optional promoter. The catalyst preferably comprises a base metal and a copper-modified Groups 8, 9, or 10 metal on a support comprising alumina, zirconia, or mixtures thereof. Copper is preferably present in an amount of from about 0.1 to about 1.0 percent by weight of the total catalyst weight. The base metal preferably comprises manganese, chromium, gold, their corresponding oxides, or combinations thereof. The optional promoter preferably comprises platinum, palladium, iridium, rhodium, ruthenium, or any combinations thereof.Type: GrantFiled: November 21, 2003Date of Patent: June 27, 2006Assignee: ConocoPhillips CompanyInventors: Zhen Chen, Steven R. McDonald, Shang Y. Chen, Stephan Basso, Charles R. Rapier, Angela R. Bailey-Rivers, Cemal Ercan

Patent number: 6552243Abstract: A molybdenum-loaded crystalline aluminosilicate molecular sieve that exhibits the MFI crystal structure and has a silica-to-alumina ratio of about 50:1 is useful for aromatizing a hydrocarbon feed stream. The crystalline aluminosilicate preferably has an external surface acidity selectively passivated by means of an amorphous silica layer. A process for the aromatization of methane comprises a one- or multi-step process that contacts a feed stream comprising at least methane with a catalyst composition comprising the preferred molecular sieve, at hydrocarbon conversion conditions that include a temperature of 600-800° C., a pressure of less than 5 atmospheres absolute and a Weight Hourly Space Velocity (WHSV) of 0.1-10 h−1, with the external surface acidity of the crystalline aluminosilicate preferably selectively passivated by an amorphous silica layer. C6-plus aromatic hydrocarbons are preferably recovered from the process by means of an intermediate separation step.Type: GrantFiled: July 27, 2001Date of Patent: April 22, 2003Assignee: Conoco Phillips CompanyInventors: Joe D. Allison, Stephan Basso, Marc LeDoux, Cuong Pham-Huu, Harold A. Wright
