چکیده مقاله:

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 petrochemical industry.Also hydrogen is produced as a subsidiary in the process. In this research, platinium-rhenium isused as a catalyst with the combination of "Re=0.4"and"Pt=0.3".the activity and selectivity of thecatalysts have been determined under condition at 350- 450oC and 30at. Pressure molar ratioH2/C7H16=5 and VVH=1.5 mL/h.Our results proved that this catalyst produces good products under 30 atmosphere pressure andtemperature ranges between 350 - 450oC but at higher temperatures such as 490 oC and over willgenerate lots of cracking and low quality black products that can not be analyzed bychromatography. This shows that in these temperatures the action of cracking is very much.However in temperature lower than 490 oC, the products have yellow color and this shows theexistence of aromatic compounds.In comparison between two catalysts with different percentages 0.3Pt=0.4Re catalyst has moreactivity. It also shows more selectivity in aromatization in comparison with 0.3Pt-0.3Re catalyst.
