Study on n-Decane Removal by Plasma Assisted Noble Metal Catalysis
摘要
Abstract
A one-stage dielectric barrier discharge catalytic reaction system was used to treat simulated diesel engine exhaust gases (n-decane, C10). Effects of different noble metal catalysts on C10 removal were studied and factors of catalyst loading amount, C10 initial concentration, reaction temperature and energy density on C10 removal were discussed. The results show that comparing with only plasma or thermal catalysis, plasma catalysis can significantly improve C10 removal rates. The synergistic effect of plasma and catalyst is prominent. The catalytic performance of Pt/Al2O3 is better than that of Pd/Al2O3 and Ag/Al2O3. The conversion rate of C10 with Pd/Al2O3 is higher, and it also contributes to the oxidization of CO into CO2. The increase of catalyst loading amount, energy density and reaction temperature can improve removal rates and COx selectivity of C10. The maximum removal rate is up to 91% and the highest COx selectivity is 54.3%. The increase of C10 initial concentration is not helpful to C10 removal.关键词
