Effect of Additives on Isomerization of Hexane over PtGa-Mordenite Catalysts

Abstract

PtGa (or Zn)/mordenite catalysts were prepared by incipient wetness impregnation of mordenite (H-MOR) with 1.0%Pt and Ga (or Zn) solutions, respectively. The catalysts were calcined, activated under flowing N2 then reduced in H2. They were characterized by X-ray diffraction (XRD), nitrogen adsorption method (BET) and temperature programmed desorption (TPD). The influence of various parameters affecting on the conversion of hexane was investigated. The reaction products are formed from isomerization, cracking and aromatization reactions. Effect of additives: MgO, ZrO2 and MgAlO was studied.
