Patent number: 10155196Abstract: A catalytic converter reactor having in-built catalytic converter modules, wherein the total flow impingement surface area provided by the catalytic converter elements fitted in the catalytic converter modules is larger than the flow impingement surface area of the catalytic converter reactor, the module impingement surface area being defined by the catalytic converter module surfaces facing the main flow direction, and the catalytic converter modules being positioned so that the waste gas flows through the catalytic converter elements contained therein in a direction different from the flow direction on the intake and exit sides.Type: GrantFiled: June 20, 2014Date of Patent: December 18, 2018Assignee: IBIDEN PORZELLANFABRIK FRAUENTHAL GMBHInventors: Kurt Orehovsky, Michael Aumann, Andreas Hartung, Thomas Krainer, Thomas Nagl, Gerhard Poelzl, Mario Schweiger

Publication number: 20100154640Abstract: Process for purifying and/or regenerating gases, in which the gas to be treated is fed to at least one layer of adjacently arranged prismatic honeycomb bodies (1) made of a ceramic material, which honeycomb bodies are provided with a plurality of channels (1?) which are parallel to one another and terminate in the end faces of the honeycomb bodies and through which the gas to be treated flows. The honeycomb bodies (1) are arranged in the layer at a predetermined lateral distance therebetween, which is fixed by two spacers (2) applied at two adjoining honeycomb body side walls (1?).Type: ApplicationFiled: December 15, 2006Publication date: June 24, 2010Applicant: Porzellanfabrik Frauenthal GmbHInventors: Christoph Hagg, Franz Kronabeter, Alfred Schmuck
