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-heptane. The results showedthat in the presence the catalyst is stable and has much higher selectivity for aromatization reaction. It wasshovm that Ta modifies the acidity of support, resulting to higher selectivity for eternalization, and modifies theproperties of the Pt catalyst.
