摘　　要：本文利用 X-光衍射、吸附仪等手段研究了 γ- Al2 O3、Co- Mo- K/γ- Al2 O3系耐硫变换催化剂和镁铝尖晶石样品在含水蒸汽气氛下 ,特别是水煤气变换气氛下 γ- Al2 O3的物性变化。给出了随温度和水 /气比变化的 γ- Al2X ray diffraction (XRD),adsorption were used to investigate the change in property of γ Al 2O 3, Co Mo K/γ Al 2O 3 sulfur tolerant shift catalyst or Mg Al spinel under steam containing atmosphere, eapecially that of γ Al 2O 3 under atmosphere of water gas shift reaction. The law in crystalline transformation of γ Al 2O 3 with temperature and water/gas ratio was given.
