研究了γ-Al_2O_3或SiO_2载体,以及反应条件对Pt/BaKL沸石催化剂芳构化性能的影响。发现经过碱化或负载Sn的γ-Al_2O_3作为载体,能够较好地保持该催化剂在正己烷芳构化反应中的高活性和高选择性,并有益于改善Pt/BaKL沸石催化剂的抗硫性能。
The effects of γ-Al 2 O 3 or SiO 2 support and the reaction conditions on the aromatization of Pt / BaKL zeolite were investigated. It was found that the alkalized or Sn-loaded γ-Al 2 O 3 as support could better maintain the high activity and high selectivity of the catalyst in n-hexane aromatization and improve the sulfur resistance of the Pt / BaKL zeolite catalyst .
