运用固定床流动态反应装置和压汞仪等手段考察了 γ- Al2 O3 载体的比表面和孔结构对常温 COS水解催化剂反应性能的影响。结果表明 ,载体必须具有适当的比表面积和孔结构 ,以利于反应物分子在催化剂表面吸附并与活性中心接触 ,同时也有利于产物分子脱附并离开催化剂表面 The effects of specific surface area and pore structure of γ-Al2 O3 support on the reaction performance of COS catalyst were investigated by means of immobilized bed flow dynamic reactor and mercury porosimeter. The results show that the carrier must have the appropriate specific surface area and pore structure, in order to facilitate the adsorption of reactant molecules on the catalyst surface and contact with the active site, but also conducive to product molecules desorption and leave the catalyst surface
