摘要：
The bifunctional catalysts of molybdenum phosphide supported on H beta zeolite (MOP/H beta) were prepared using a co-impregnation-temperature-programmed reduction method, and catalytically tested in the hydroisomerization of n-heptane. The catalytic conversion and isomerization selectivity of MoP/H beta were revealed to be higher than those of the control tungsten phosphide sample WP/H beta and the HMCM22-supported counterpart MOP/HMCM22. Moreover, doping Cr, Ni, or Ce significantly improved the activity of MoP/H beta; meanwhile, the Cr-promoted catalyst also gave an enhanced selectivity to isomerization products. The catalysts were characterized by X-ray diffraction, Brunauer-Emmett-Teller analysis, temperature-programmed desorption of NH3, and temperature-programmed reduction of H-2. Accordingly, it is suggested that the promoting effect of the secondary metal additive is relative to the reduction of MOPOx species, as well as the pores and add sites of the beta zeolite.
