چکیده مقاله :

Bimetallic Pt-V supported by Gamma-alumina is used to observe the changes of nheptanewhen passed over this catalyst. The Pt concentration was kept constant at0.1wt% while the concentration of the vanadium was 0.5wt%. The activity andselectivity of catalyst have been determined under conditions at 450-500 degreescentigrade and 15-30 attn. The experimental results show that the addition of secondmetal to the Pt catalyst results in a modification of the metal and acid functions. Theresults show that when vanadium is present, the catalyst has high selectivity foraromatization reaction.
