研究了新疆几类高岭土的化学成分、矿物组成、铁的赋存状态、物理性质（粒度、比表面积和孔体积）和催化特性.结果表明:（1）在所研究的新疆高岭土样品中,只有伊宁浅色地开石可用作FCC催化剂载体,但还需进一步扩大深人研究;（2）高岭土用作催化裂化催化剂载体,其成因类型、矿物组成、化学成分、矿物结构特征、物理性质等对催化性能均有重要影响.
The chemical composition, mineral component, the condition of occurrence of iron, IR spectroscopy, physic
properties and catalytic properties of kaolin clays in Xinjiang are presented in this paper. The study of application of Xinjiang dickite in catalyst carrier
should be lucubrated. The catalytic properties of kaolin are affected by their genesis, chemical composition, mineral component, structure of mineral and
physical properties. The study of correlation between mineralogical characteristics and catalytic properties of catalyst carrier should be
strengthened.
