摘要: Abstract n -Hexane aromatization was investigated at 500 °C on parent and metal (i.e. Ga, Mo Zn) modified H-ZSM-5 zeolite catalysts. Conversion reached 88% over stable. Addition of resulted in lower conversion ( 35%) Zn/H-ZSM-5 (> 40%) while Mo/H-ZSM-5 showed higher cracking activity. Gallium zinc favored aromatization. At 600 °C a decrease activity with increasing TOS observed. A aromatics selectivity also The increase Ga/H-ZSM-5 (43–27%) (35–27%) catalysts than for (46–7%).
