摘要
本文用电子能谱(xps)方法研究了我国九个不同牌号煤中有机硫的存在形态,并得到这些煤中各种不同形态硫的结合能数据。根据Lindberg等人所做的模型化合物结果,给出了这些煤中硫元素结合能的化学归属。各种煤中硫的存在形态是不同的,有硫醇、硫醚、双硫醚、硫杂环、硫桥和取代基上的硫等,这一研究结果为今后研究煤的分子结构及脱硫方法提供了重要的科学依据。
The existing froms of organic sulphur in some Chinese coals with different ranks were studied by XPS. The binding energy of sulphur which exists in different forms were obtained, Chemical forms of sulphur in these coals were classified by their binding energies on the basis of the results of model compounds. The forms of sulphur element in coals of different rank were not the same, they had wide distribution in coal, such as mercaptan, sulphur ether, disulphurether, sulphur heterocyclic ring, sulphur bridge and sulphur on substituents. These results give further information to study the structure of coal and explore new methods of desulphurization.
