This work shows how propane was catalytically converted to aromatic compounds over Zn-Ni/HZSM-5 investigate the synergistic role of nickel as a zinc stabilizer and promoter in aromatization. Co-impregnation method employed for Zn-Ni/ZSM-5 synthesis fixed 2 wt% 1, 3 nickel. Modified catalysts’ were fully characterized. Catalysts crystallinity, structure microporosity retained from analysis resul...

The activity of different transitional metals over modified H-ZSM-5 catalysts for methane conversion to aromatics was compared. The first group of catalysts was Mo-impregnated H-ZSM-5 zeolites with 1, 3 and 6 wt% of Mo. The second group was M(3 wt%)- impregnated H-ZSM-5 (M: Ag, Cd, Cr, Mo, Zn and Mn). The catalytic activity of the first group was investigated at 600, 700 and 800 °C and gas hour...
