摘要
研究了大孔聚苯乙烯系吸附树脂Ｄ３５２０负载的钯铁催化剂的结构及氢化对硝基氯苯的性能．结果表明该催化剂具有较好的表面物理状态，金属在载体表面高度分散，分布均匀，金属间有较强的相互作用．动力学分析表明反应速率对底物浓底有一极大值，可能为ＬＨ机理．反应为双分子吸附的表面反应．
The catalyst was prepared by supporting PdFe on macroporous polystyrenediethyl benzene adsorption resin(D 3520 ). Its structure and hydrogenation abilities for p ClC 6H 4NO 2 have been studied. It showed that this catalyst has good surface state. The metals were highly dispersed and uniformly distributed throughout the matrix. There was a interaction between metals. The reaction kinetic properties of hydrogenation of p ClC 6H 4NO 2 on PdFe/D 3520 may be bimoleculeadsorbed surface reaction.
