| 20090025375 | Catalyst composition and structure for a diesel-fueled autothermal reformer placed in and exhaust stream - The inventions relates to catalysts comprising precious metals supported on La stabilized refractory metal oxides. The La is provided on the surface of the refractory metal oxide in an amount to form at least about a monolayer, preferably about 1-2 mono-layers. Preferably, the La has no crystalline structure shown by X-ray diffraction. Nd and mixtures of La and Nd can be used in place of La. In one embodiment, the catalyst is a reforming catalyst comprising an effective amount of Rh on a ZrO | 01-29-2009 |
| 20090120072 | Pre-combustor and large channel combustor system for operation of a fuel reformer at low exhaust temperatures - An exhaust aftertreatment system is provided with a large channel combustor, a fuel reformer, and a lean NO | 05-14-2009 |
| 20100203238 | Preparation method for a partially coated monolith - Processes are provided for making partially coated monolith catalysts that are useful, for example, as pre-combustor catalysts for diesel exhaust aftertreatment. Monolith substrates are provided with interconnectivity and/or temporary barriers that allow from about 10 to about 90% of the monolith channels to be coated after the monolith substrate is assembled without having to carefully pick out among a large number of openings which ones to inject into or which ones to plug. The invention includes options of injecting into a multipath monolith substrate and of emplacing blocking material during monolith construction. Either catalyst coating material or coat-blocking material can be injected. Blocking materials allow the use of machinery for ordinarily non-selective processes, such as machinery for dip coating. Both multipath injections and pre-placed barriers can be used in a single partial coating process. | 08-12-2010 |
