Web24 de ago. de 2024 · Fe-ZSM-5 catalysts modified by Cu and Ce by aqueous solution ion-exchange and incipient wetness impregnation methods were tested in the selective catalytic reduction of NOx with NH3. A variety of characterization techniques (NH3-SCO, BET, XRD, XPS, UV-Vis, NH3-TPD, H2-TPR) were used to explore the changes of the active sites, … WebSupported Pt catalysts have been extensively investigated for CO2 hydrogenation with methane and CO as the principal products. In this work, a Pt/In2O3 catalyst prepared with decomposition precipitation was tested for CO2 hydrogenation to methanol. The Pt/In2O3 catalyst exhibited a highly improved activity towards CO2 hydrogenation, with methanol …
High Conversion to Aromatics via CO2 - ACS Publications
Web13 de nov. de 2015 · The effects of alkaline treatment on the physical properties of ZSM-5 catalysts and on their activities for methanol to aromatics conversion have been investigated. A mild alkaline treatment (0.2 and 0.3 mol/L NaOH) created mesopores in the parent zeolite with no obvious effect on acidity. The presence of mesopores gives the … WebAbstract CO2 hydrogenation to methanol is of great significance for the emission control and utilization of CO2. In this work, the Rh/In2O3 catalyst with high Rh dispersion was prepared by deposition-precipitation method. The catalyst characterization demonstrates that the highly dispersed Rh species promotes the dissociative adsorption and spillover of … cumberland maine harness racing
