中温煤焦油中类型Fe的分布特征
Distribution of Fe types in medium temperature coal tar
摘要
Abstract
Different types of Fe in medium temperature coal tar were separated and determined by means of ICP. Toluene-insolubles in the coal tar were characterized by means of SEM,EDX,FTIR, XRD and element analysis. The experimental results showed that,toluene-insoluble Fe,oil-soluble Fe and water-soluble Fe in the coal tar were 66.64%(w),33.03%(w) and 0.33%(w) of the total Fe content,respectively. The characterization results showed that the toluene-insolubles in the coal tar had high degree of aromatization and contained a lot of polycyclic aromatics. Fe might be combined with the polycyclic aromatics containing sulfur,nitrogen,oxygen and other heteroatoms. A small amount of Fe in the toluene-insolubles existed in clay-like inorganic minerals which might derive from coking coal ash.关键词
