2. 1. Investigation of La promoted Pd/BEA Performance for Passive NOx adsorption processes

   Author : Rojin Feizie Ilmasani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NO TPD; Ceria; Zirconium; Lanthanum; Pd BEA; PNA; CO effect;

   Abstract : Lean-burn combustion engines have been used to improve fuel efficiency by reducing fuel consumption. However, these engines face challenges in lean reduction of NOx for exhaust after-treatment systems. READ MORE

4. 2. Mechanism of the passive NOx adsorption process on zeolite-supported Pd in controlling cold-start emissions
