Patent number: 7080505Abstract: A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate by a silicone binder producing high adsorption efficiencies while withstanding relatively high regenerative heat temperatures resulting from exhaust gas sensible heat. A hydrocarbon senses HC in the desorbed heated atmosphere stream to rotatively and sequentially index pie shaped, segmented portions of the wheel into the wheel's regenerative region while also functioning as the main component of an OBD device for the system.Type: GrantFiled: July 8, 2003Date of Patent: July 25, 2006Assignee: Engelhard CorporationInventors: Gerald S. Koermer, Jeffrey B. Hoke, Ronald M. Heck, Terence C. Poles, Edward T. Wolynic

Patent number: 6375905Abstract: A metal substrate is fabricated and coated with a catalyst for ozone conversion of atmosphere passing through the substrate. A plurality of aluminum foil sheets that have been slit, stretched and twisted into a plurality of regularly repeating channels having geometrically shaped openings are serially positioned one on top the other to form a foil stack with channel openings partially blocked by channel walls of overlying foil sheets. Thicker covers with openings at the top and bottom of the stack form a sandwich and the sandwich pleated to form corrugations in a flexible but rigid sandwich substrate. The channel walls are coated with an ozone depleting catalyst which the ozone atmosphere contacts to remove ozone as the ozone atmosphere travels through the stack construction.Type: GrantFiled: February 11, 2000Date of Patent: April 23, 2002Assignee: Engelhard CorporationInventors: Ahmad Moini, Kenneth Charles Fisher, Christopher R. Castellano, Jeffrey Barmont Hoke, Ronald M. Heck
