Study of catalytic performance of LaMnO3 and LaMnO3-ZSM-5 nanocatalysts toward 2-propanol conversion
LaMnO3 and LaMnO3/ZSM-5 nano catalysts were synthesized by Pechini method and their physical-chemical properties were characterized using XRD, FTIR, SEM-EDX, UV-vis DRS, BET surface area and TPR. The correlation between characteristic properties and activity of catalysts were investigated. The catalytic performance of the catalysts was evaluated in combustion of 2-propanol...
متن کاملEnhancing P-xylene selectivity during m-xylene transformation using mildly pre- coked ZSM-5 catalyst
In the present work, the transformation of m-xylene was studied over fresh and pre-coked HZSM-5 catalyst in a riser simulator over the temperature range of 350-500C.Significant differences were observed in both the activity and product selectivity pattern for the two forms of the catalyst. While, the fresh catalyst generally gave higher m-xylene conversion, the pre-coked catalyst produced highe...

متن کاملCatalytic Performance and Characterization of Promoted K-La/ZSM-5 Nanocatalyst for Biodiesel Production
The promoted K-La nanocatalysts supported on ZSM-5 zeolite were prepared via wetness impregnation method and tested for biodiesel production from soybean oil. The effects of different weight percentage of La, loading of K as a promoter and calcination conditions on structure and activity of catalyst were investigated. Results showed that the supported catalyst containing 7wt.% of La was pro...
متن کاملTheoretical evidence of the observed kinetic order dependence on temperature during the N(2)O decomposition over Fe-ZSM-5.
The characterization of Fe/ZSM5 zeolite materials, the nature of Fe-sites active in N(2)O direct decomposition, as well as the rate limiting step are still a matter of debate. The mechanism of N(2)O decomposition on the binuclear oxo-hydroxo bridged extraframework iron core site [Fe(II)(mu-O)(mu-OH)Fe(II)](+) inside the ZSM-5 zeolite has been studied by combining theoretical and experimental ap...
