摘　　要：球形炭化树脂作为催化剂载体具有许多独特的优点，为炭素材料催化剂开拓了新的前景。在诸多炭化树脂催化剂的制备方法中，离子交换－炭化法具有许多优点，是重要的制备方法之一。本文从Ｄ１５２大孔弱酸阳离子交换树脂为前驱载体，用不同的预处理方法先制成钙型Ｄ１５２树脂（Ｃａ／Ｄ１５２），然后同Ｎｉ的ＮＨ３－ＮＨ４＋水溶液、乙醇水溶液进行离子交换，再经炭化后制成了高分散度、高强度的栽体镍炭化树脂（Ｎｉ／Ｃ）催化剂。本文对各种制备条件与（Ｎｉ／Ｃ）催化剂的结构性能的关系进行了讨论。Ion-exchange-carbonization is an important method adopod in the preparation of metal-doped carboned resin. calcium-doped D152 resin (Ca/D152) was prepared with D152 ion exchange amberlyst acrylic acid as.the precursor of supporter by different pretreatment methods. Nickel-doped D152 resin (Ni/D152)was obtained via Ca/D152 ion-exchanging with Ni2+ in NH3-NH4+ solution and EtOH solution, then was csrbonized. The nickel-doped carboned resin(Ni/C) catalyst with high metal dispersity and mechanical strength was obtained.The relations between different preparation conditions and Ni/C surface properties were also discussed.
