초록정보

A series of Pt and Pt-Re catalysts has been prepared by impregnation of $γ-Al_2O_3$ and HY-Zeolite. The catalyst has calcined in dry air and reduced by hydrogen. The transformation of n-hexane has been carried out under atmospheric hydrogen pressure on supported Pt and Pt-Re catalysts. The activity maintenance of Pt-Re catalysts was better than Pt catalysts. At high reaction temperature above 400℃, γ-alumina supported Pt-Re catalyst was more active and more selective for benzene than γ-alumina supported Pt catalysts. According to increasing reaction temperature from 400℃ to 450℃, deactivation was significant for γ-alumina supported Pt-Re catalysts. At this range of temperature the selectivity for benzene and cracking was increased. The selectivity for isomerization was higher for HY-Zeolite supported catalysts than γ-alumina supported catalysts. At reaction temperature above 450℃, HY-Zeolite supported Pt-Re catalysts were deactivated rapidly and more selective for cracking and benzene. The Pt-Re catalyst calcined at higher temperature had poor activity maintenance.
