Investigation of Activity and Selectivity of n-Heptane by Reforming Pt-Ta Catalyst Supported on y-Alumina
The catalyst Pt-Ta supported on 7-alumina was prepared by impregnation with solution containing compoundsof II21K1.0. and Ta205 The Pt concentration was kept constant at 0.2 vet% while the concentration of thetantalum was 0,4 wt%. The activity and selectivity of catalyst were determined under conditions at 450-500 °Cand 15-30 atm.. with molar ratio H2/C[H,e5 and WH=1.5mL/h for converted n-hepta...
متن کاملCatalytic removal of nitrogen dioxide in the air stream by nickel and nickel- platinum supported multiwall carbon nanotube.
Introduction Nitrogen oxides as one of the most dangerous environmental pollutant, have harmful effects on the health of people in the workplace. Today, the catalytic oxidation of nitrogen oxides is a highly efficient method for removing of this gases that has been dedicated part of researches. The aim of study was to investigate the removal efficiency of nitrogen dioxide (NO2) by nickel and...
متن کاملCATALYTIC REFORMING OF n-HEPTANE ON PLATINUM-TUNGSTEN SUPPORTED ON GAMMA-ALUMINA
The mono-metallic and bi-metallic catalysts have been prepared by impregnating with solutions containing a compound of H2PtCl6,WO3 and 1ml HCl (0.1 mol). It should be noted that the catalysts’ activity and selectivity have been determined under these conditions : 450-5000C ,and 15-25atm by H2. For converting n-heptane , the molar ratio H2/C7H16 is 5 , and LHSV is 1.5ml/h. It has been proved tha...

متن کاملEffect of Nickel Particle Size on Alumina Supported Nickel Catalysts for p-Nitrophenol Hydrogenation
The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated over alumina supported nickel catalysts prepared by impregnation reduction method and mechanical mixing method. The catalysts were characterized by XRD and FESEM. The results show that the nickel particle diameter of alumina supported nickel prepared by impregnation reduction method (denoted as Ni/Al2O3) is slightly ...
