摘要
对煤炭坝矿区硫的成因、硫在煤中的赋存状态及赋存规律进行了研究 .结果表明 :煤炭坝 2煤中的硫以有机硫占绝对优势 ,次为硫化铁硫 ;有机硫主要以硫醇、硫化物与二硫化物、噻吩及其衍生物等形式存在 ;有机硫的成因与成煤植物中菌藻类的参与、海水中硫酸盐的不断供给、介质具弱碱性、还原性和微生物活动及活性铁离子受限有关 .在此基础上 ,对 2煤中硫的可选性作出了评价 .表 2 ,参 6.
The cause of formation of sulfur and its state and regulation of occurrence are studied in this paper. The results show that the contents of organic sulfur of No. 2 coal seam in Meitanba mining area are much greater than that of the other formal sulfur, and the contents of sulfur of sulfuriron arrange in second. The organic sulfur mainly exists in the form of sulfur wine, sulfide, sulfur dioxide, thiophene and its derivative etc. The cause of formation of organic sulfur has relation to participation of bacterium and algae; continuous supply of sulfate in seawater, weak basicity and reduction and activity of microorganism in medium, restriction of lively iron ion. On the basis of this, the separation of sulfur of No. 2 coal seam is evaluated. 2tabs., 6refs.
