Selective Catalytic Reduction of CuO/SiO2 Nano-composites towards NO Reduction in Gas-phase
The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7. Also, the necessary amounts of tri-hydrated copper nitrate and penta-hydrated copper sulfate were added to the solution in such a manner that the concentration of the copper oxide in final solut...
متن کاملCatalytic Activities of Transition Metal Phosphides for NO Dissociation and Reduction With CO
Transition metal phosphides are a group of compounds with interesting chemical/physical properties and potential applications in various fields, such as electronics, magnetism, photonics, catalysis, and so on1–4. In particular, metal phosphides (e.g. MoP, Ni2P, WP, Fe2P and Co2P) have been used as catalysts and extensively studied for hydrotreating reactions5–8. Among these phosphides, MoP, Ni2...
متن کاملModeling Transport Phenomena in Selective Catalytic Reductant Catalytic Converter with NH3 as Reductant for NO Degradation
In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...
متن کاملOptimization and Modeling of CuOx/OMWNT’s for Catalytic Reduction of Nitrogen Oxides by Response Surface Methodology
A series of copper oxide (CuOx) catalysts supported by oxidized multi-walled carbon nanotubes (OMWNT’s) were prepared by the wet impregnation method for the low temperature (200 °C) selective catalytic reduction of nitrogen oxides (NOx) using NH3 as a reductant agent in the presence of excess oxygen. These catalysts were characterized by FTIR, XRD, SEM-EDS, and H2-TPR meth...
