摘要
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 。
Influence of surface area and pore structure of γ Al 2O 3 carrier on reaction property of ambient temperature COS hydrolysis catalyst was studied using fixed bed flow type reactor and pore sizer.Results show that carrier should have appropriate surface area and pore structure so as to facilitate adsorption of reactant molecules on catalyst surface and their contact with active sites,as well as desorption and leaving of product molecules from catalyst surface.
