摘要
煤系黄铁矿可作为煤直接液化过程中一种廉价、有效的可弃性催化剂．运用Ｘ光电子能谱分析测试了煤系黄铁矿催化剂的表面元素组成与形态分布，研究了煤系黄铁矿表面不同形态硫、碳的分布特征，并应用电视显微电泳仪测得煤系黄铁矿样品的零电点（ＰＺＣ）在ｐＨ＝４６左右．
Coal derived pyrite can be used as a cheaper and disposable catalyst with high catalytic hydrogenation activity during direct coal liquefaction. In this paper, the elemental composition and form distributions on the surface of coal derived pyrite catalyst have been investigated by XPS, with particular emphasis on the distribution characteristics of different form sulfur and carbon. In addition, the point of zero charge of coal derived pyrite sample was determined at about pH=4 6 by means of television micro electrophoresis apparatus.
