Synthesis and Application of Pt-Re/ Al2O3 Naphtha Reforming Nano-Catalyst

The effect of Pt-Re/Al2O3 nano-catalyst bimetal catalyst synthesis method over its physiochemical behaviors and its application are investigated in this article. The catalysts synthesized by microemulsion method and their applications are compared to those synthesized by impregnation in N-Heptane reforming reaction at 500 ºC and 1 atm. The catalysts are characterized by nitrogen adsorption isotherms, ICP and TPR. The results of TPR show that the microemulsion method leads to stronger interaction of metal particle with the support. Also the use of microemulsion method leads to an increase in the metal dispersion and reduces the particle size. The microemulsion method leads to increase in the activity of catalyst from 0.26% to 50%. In addition, the selectivity of benzene increases from 3.15% to 9.61%; while, the toluene selectivity rises from 2.34% to 6.075% and selectivity of methyl cyclohexane increases from 2.3% to 8.04%. Also, the methane selectivity decreases from 2.4% to 1.05%.
