Nox and Diesel Soot Abatement over Catalytic Traps Based on Mixed Trasition Metal Oxides
Nanostructured perovskite-type oxides catalysts La1-xAxNi1-yByO3 (where A = Na, K, Rb and B = Cu; x = 0, 0.2 and y = 0, 0.05, 0.1), prepared by the solution combustion synthesis method and characterized by BET, XRD, FESEM, and catalytic activity tests in microreactors, proved to be effective in the simultaneous removal of soot and NO, the two prevalent pollutants in diesel exhaust gases in the ...
متن کاملCatalytic evaluation of promoted CeO2-ZrO2 by transition, alkali, and alkaline-earth metal oxides for diesel soot oxidation.
Series of mixed metal oxides were synthesized by gel-combustion method and their catalytic activities for soot oxidation were investigated. The catalysts were M-Ce-Zr (M = Mn, Cu, Fe, K, Ba, Sr), and xK-20Mn-Ce-Zr (x = 0, 5, 10, 20), they were characterized by XRD, SEM, TPR and BET surface area techniques. The results of soot temperature programmed oxidation (TPO) in an O2 oxidizing atmosphere ...
متن کاملThree-Dimensional Modeling of Combustion Process, Soot and NOx formation In a Direct-injection Diesel Engine
This paper is presented to study the combustion process and emissions in a direct injection diesel engine. Computations are carried out using a three-dimensional model for flows, sprays, combustion and emissions in Diesel engines. Interactions between combustion and emissions with flow field are considered and it is shown that soot mass fraction increases at regions with low turbulence inten...
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 کاملExperimental and Kinetic Study of CO Oxidation Over LaFe1-xCuxO3 (x=0, 0.2, 0.4, 0.6) Perovskite-Type Oxides
In this paper, catalytic oxidation of CO over the LaFe1-xCuxO3 (x= 0, 0.2, 0.4, 0.6) perovskite-type oxides was investigated. The catalysts were synthesized by sol-gel method and characterized by XRD, BET, FT-IR, H2-TPR and SEM methods. The catalytic activity of catalysts was tested in catalytic oxidation of CO. XRD patterns confirmed the synthesized perovskites to be single-phase perovskite-ty...
