用 TPSR法对丙烯在硫酸镍高分散型催化剂上反应过程进行考察 ;用 NH3 - TPD法对 NH3吸附中心进行跟踪 ,发现除强弱两类酸中心外 ,确有第三类活性中心 ,此第三类活性中心可能就是配位催化活性中心 .用准原位 EPR,XPS方法观察到活性中间态 Ni+的存在 .UV- DRS谱图发现 :不同温度吸附丙烯后 ,出现不断变化的新的吸收信息 .由此对配位催化过程提供部分论证 TPSR method was used to investigate the reaction process of propylene on highly dispersed nickel sulfate catalyst. The NH3 adsorption center was traced by NH3 - TPD method. It was found that there was a third type of active center besides the strong and weak acid centers. The three kinds of active centers may be coordination catalytic activity centers. The presence of active intermediate Ni + is observed by the in situ EPR and XPS methods. The UV-DRS spectrum shows that there are constantly changing new absorption information after propylene adsorption at different temperatures This provides some evidence for the coordination catalytic process
