| 摘 要： | 研究两种内蒙古煤系高岭土（1＃、2＃）的化学组成、晶体结构并与苏州高岭土进行了比较。对三种高岭土进行酸改性，利用BET、吡啶-TPD和微反测试分别研究改性前后高岭土的性能特点。并将内蒙古高岭土1＃与苏州高岭土采用半合成方法合成了FCC催化剂，测定了其裂化活性。研究结果表明，内蒙古1＃具有较良好的晶体结构和化学组成，经酸改性后比表面积大大增加，具有合适的孔径分布，裂化活性较好，可以取代苏州高岭土作为FCC催化剂的基质。

| Abstract: | The composition and crystalloid structure of two sorts of coal-derived kaolin from Inner Mongolia were studied and treated by HCl.The acid-modified kaolin was characterized by pyridine-TPD,BET.FCC properties of the partiallysynthesized samples from Inner Mongolia and Suzhou was compared by activity test.The results showed that the kaolin from Inner Mongolia had good composition and crystalloid structure;the pore distribution and surface area was greatly improved after acid-treatment,exhibiting good cracking activity.The Inner Mongolian kaolin could be alternative to Suzhou kaolin as the matrix for FCC catalyst. |

| Keywords: | Inner Mongolian kaolin acid-treatment FCC activity matrix |
