Research on Effects of Different Promoter Metals on Ir Catalyzed Propane Dehydrogenation
Three bimetallic catalysts,IrZn/SiO2,IrGa/SiO2,and IrSn/SiO2 modified by different metal promoters(Zn,Ga,and Sn)were used to investigate the effects of different metal promoters on the structure of Ir active sites and propane dehydrogenation performance.A series of results showed that the dispersion of Ir sites significantly affected the catalytic performance.
