Preparation and performance analysis of γ-Al2O3 supported Cu-Ru bimetallic catalysts for the selective Wet Air Oxidation of Aqueous Ammonia to Nitrogen.
Series of Copper Ruthenium (Cu-Ru) bimetallic catalysts supported on γ-Al2O3 with different metal loading are prepared and investigated for catalytic wet air oxidation of ammonia to nitrogen. The ammonia decomposition activity was studied at three different temperatures i.e. 150oC, 200oC, and 230 oC and it is found that catalytic activity increases with the increase in temperature along with th...
متن کاملThe characteristics of wet air oxidation of phenol over CuOx/Al2O3 catalysts: effect of copper loading.
The nature of active copper species is well-known to vary with copper loading, i.e., isolated Cu(2+) to bulk CuO. In this work, however, the effect of copper loading on the activity and the selectivity was investigated for the wet oxidation of phenol over CuO(x)/Al(2)O(3) catalysts. The activity and the mineralization selectivity of the catalysts increased with copper loading up to 7wt% and rem...
متن کاملH2 Production from Partial Oxidation of iso-Octane over Ni/Ce0.75Zr0.25O2 and Ni/β- Al2O3 Catalysts
In this study, the partial oxidation of iso-octane over Ni/Ce0.75Zr0.25O2 and Ni/βAl2O3 catalysts was investigated. The results indicated that Ni/Ce0.75Zr0.25O2 is more active than Ni/β-Al2O3. The partial oxidation products are mainly H2 and CO for Ni/Ce0.75Zr0.25O2 with hydrogen selectivity up to 85%. The H2/CO ratio is in the range of 1.3-2.0 depending on the operating temperature. It was n...
متن کاملEffects of Al2O3 support modifications on MoOx and VOx catalysts for dimethyl ether oxidation to formaldehyde
Dispersed two-dimensional MoOx and VOx oligomers on Al2O3 and SnOx-modified Al2O3 supports were examined for selective dimethyl ether (DME) oxidation to HCHO and their structure and reduction rates in H2 were determined using Raman and X-ray near edge absorption spectroscopies (XANES), respectively. Modifying Al2O3 supports with SnOx or other reducible oxides (ZrOx, CeOx and FeOx) led to MoOx d...
متن کاملSynthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
