20080227629 | OXIDATION CATALYSTS - The present invention relates to an oxidation catalyst comprising a substrate and an oxidation coating of platinum (Pt), palladium (Pd), cobalt (Co), iron (Fe) and cerium (Ce) applied to the substrate. Furthermore the invention relates to a method for producing such an oxidation catalyst and an internal combustion engine using such an oxidation catalyst. | 09-18-2008 |
20090238744 | Catalyst System for CO-Removal - The invention relates to a catalyst system for the removal of carbon monoxide from a hydrogen containing feed gas. The system includes a first catalyst optimised to selectively oxidize carbon monoxide in the feed gas at temperatures below 100° C. The system also includes a second catalyst, downstream from the first catalyst, optimised to selectively oxidize carbon monoxide in the feed gas at temperatures above 100° C., the second catalyst having a higher carbon monoxide conversion rate than the first catalyst at 100° C. | 09-24-2009 |
20120214663 | LNT AND SCR CATALYSTS FOR COMBINED LNT-SCR APPLICATIONS - The current invention refers to the LNT and the SCR catalysts designed for combined LNT-SCR applications. LNT catalysts are based on proton-conducting oxides of fluorite structure, namely Ca (Sr)—La—Ce (Zr, Pr) mixed oxides in which up to 40 mol-% of lanthanum is replaced by calcium and/ or strontium, and up to 66 mol-% of cerium is replaced by zirconium and/or praseodymium, further combined with Pt—Pd or Pt—Pd—Rh precious metal components. SCR catalysts are Cu/zeolite modified by citrate treatment or Cu—Ce, Mn—Ce or Co—Ce/modified zeolite. | 08-23-2012 |
