Diesel soot combustion ceria catalysts
This review article summarizes the contents of the keynote lecture with the same tittle presented at the 7 th edition of the International Conference on Environmental Catalysis hold in Lyon (France) in September 2012. Different aspects of the ceria-catalyzed Diesel soot combustion reactions have been critically discussed, such as the high catalytic activity of ceria for Diesel soot combustion i...
متن کاملSolution Combustion Synthesis Boosts Ceria Activity towards Diesel Soot Combustion
Nano-sized particles of ceria with high surface area were processed by solution combustion synthesis (SCS) and their catalytic activity towards combustion of carbonaceous materials was compared with that obtained by simple thermal decomposition of cerium nitrate, exhibiting the same specific surface area. These two kinds of ceria powders were tested, by DTA and temperature programmed combustion...
متن کاملSoot Formation within Conventional and Low Temperature Diesel Combustion
The soot formation processes of conventional and low temperature diesel combustion were investigated by a newly developed Forward Illumination Light Extinction (FILE) soot measurement technique in a constant volume spray chamber. The FILE technique has the capability to obtain two-dimensional time-resolved quantitative soot measurements. For diesel combustion at conventional ambient condition, ...
متن کاملBaKCo/CeO2 catalysts for diesel soot and NOx abatement
Introduction Soot particles and NOx are the main pollutants from diesel engines. Good alternatives to abate these contaminants are the use of catalytic filters, which burn the soot particles, and NOx traps which adsorb the NOx during normal operation and released them during reduction cycles [1]. We recently studied BaK/CeO2 catalysts for this application[2]. Barium plays the role of NOx adsorb...
متن کاملReaction Mechanism in Catalytic Soot Combustion with CeO2 Catalysts
Introduction Diesel soot elimination is a very difficult problem. The catalytic filters seems to be one of the technological alternatives in order to trap and burn the soot, at the exhaust gas temperature. In order to advance in a rational catalyst design, the reaction mechanism must be understood. In spite of this need, and even though there are many papers in the field, detailed studies regar...
