Patent number: 8491966Abstract: Disclosed herein is a process for coating ceramic honeycomb bodies with a catalyst suspension comprising catalyst components as solids and/or in dissolved form in a carrier liquid. Parallel flow channels run through the honeycomb bodies. The walls of the flow channels have an open pore structure. To coat the channel walls and in particular also the interior surfaces of the pores with the catalyst suspension, the entry and exit end faces of the vertically aligned honeycomb bodies are each brought into contact with a perforated mask, with the perforated masks being arranged so that the open regions of the perforated mask on the one end face are opposite the closed regions of the perforated mask on the other end face and vice versa. The catalyst suspension is then pumped or sucked from below into the honeycomb bodies until it exits at the upper end face.Type: GrantFiled: March 18, 2008Date of Patent: July 23, 2013Assignee: Umicore AG & Co.

Patent number: 8476559Abstract: Tunnel kilns serve for the thermal treatment of products in a continuous operation within a production process. The tunnel kilns are usually made up of a number of identical kiln segments, each segment having a blower, heating elements for heating up the fresh air and a common exhaust air line. For the treatment of the products, they are made to pass by either on the suction side or the pressure side of the blower. To reduce the overall volume of such kilns and to save energy, it is proposed to arrange the blower inside the kiln in such a way that it produces a circulatory flow transversely to the direction of continuous transport and to transport the products to be dried through the circulatory flow parallel to one another in the direction of continuous transport both on the pressure side and on the suction side of the blower.Type: GrantFiled: November 24, 2008Date of Patent: July 2, 2013Assignee: Umicore AG & Co.

Publication number: 20080107806Abstract: Wall-flow filters can be reproducibly provided with a catalytically active coating by providing a defined quantity of a coating composition and sucking this coating composition through the openings of the entry passages into the filter body. The coating composition is sucked in by applying a subatmospheric pressure to the openings of the exit passages of the wall-flow filters. A different ratio of the coating quantities on the inner surfaces (pore surfaces) and outer surfaces (geometric surfaces of the passage walls) forms depending on the type of coating composition—suspension of fine-particle solids, colloidal solution or solution of soluble precursors of catalytically active components.Type: ApplicationFiled: August 13, 2005Publication date: May 8, 2008Applicant: UMICORE AG & CO.KGInventors: Bernd Mergner, Wolfgang Hasselmann

Patent number: 6149973Abstract: A process for the coating of the flow channels of a cylindrical, honeycomb form catalyst carrier with a dispersion coating through filling of the vertically oriented flow channels with a fill quantity of the coating dispersion through the bottom face of the catalyst carrier and subsequent downward emptying and clearance extraction of the flow channels, as well as drying and calcination of the catalyst carrier, by the following steps:a) filling of the flow channels with a fill quantity that is about 10% greater than the empty volume of the flow channels, so that the coating dispersion goes over the upper face of the catalyst carrier after completion of the filling cycle,b) removal of the excess coating dispersion at the top before emptying of the flow channels andc) emptying and clearance extraction of the flow channels through an extraction impulse, which is generated by connection of a vacuum tank with the bottom face of the catalyst carrier,whereby the time between the beginning of the fill cycle and the enType: GrantFiled: September 3, 1998Date of Patent: November 21, 2000Assignee: Degussa-Huls AktiengesellschaftInventors: Martin Foerster, Ewald Dittrich, Gerhard Birtigh, Walter Leibold, Bernd Mergner, Michael Hoffmann, Wolfgang Hasselmann, Robert Schafer
