DIESEL REFORMERS FOR LEAN NOX TRAP REGENERATION AND OTHER ON-BOARD HYDROGEN APPLICATIONS
Many solutions to meeting the 2007 and 2010 diesel emissions requirements have been suggested. On board production of hydrogen for in-cylinder combustion and exhaust after-treatment provide promising opportunities for meeting those requirements. Other benefits may include using syngas to rapidly heat up exhaust after-treatment catalysts during engine startup. HydrogenSource's development of a catalytic partial oxidation reformer for generating hydrogen from ultra-low sulfur diesel fuel is presented. The system can operate on engine exhaust and diesel fuel with no water tank. Test data for hydrogen regeneration of a lean NOx trap is presented showing 90% NOx conversion at temperatures as low as 150 degrees C and 99% conversion at 300 degrees C. Finally, additional efforts required to fully understand the benefits and commercial challenges of this technology are discussed.
