determination of activity and selectivity of n-heptane by reforming catalytic pt-v supported on gamma-alumina
نویسندگان
چکیده
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.

Catalyitic reforming is one of the refinery processes in catalyst conversion that results to anincreases in octane number of naphtan which leads to production of gasoline with higher octanenumber. Hydrocarbons with high octan number that are produced in reforming process are as;aromatics, paraffins, isomers and etc.Not only Aromatics are used as fuel for motors but they are also useful in petro...
