评述了煤中氯的研究现状，用仪器中子活化分析方法测定了中国４５个晚古生代全层煤样氯的质量分数，提出了煤中氯的逐级化学提取方法．研究表明，与其它国家相比中国煤不是高氯煤；平朔煤中氯以水溶态为主（４６．７０％～９１．７８％），其次为与煤大分子结合的有机氯（５．２０％～４８．３８％），再次为呈离子交换态的有机氯（４．９２％～１８．７８％）；煤灰分越低，有机氯质量分数相对越高． The research status of chlorine in coal was reviewed. The mass fraction of chlorine in 45 full Paleozoic coal samples from China was determined by instrumental neutron activation analysis. The chemical extraction method of chlorine in coal was proposed. The results show that Chinese coal is not high-chloride coal compared with other countries; chlorine is predominantly water soluble in Pingshuo coal (46.70% ~ 91.78%), followed by organic chlorine combined with coal macromolecules (5). 20% -48.38%), and again for the ion exchange state of organic chlorine (4.92% ~ 18.78%); the lower the coal ash, the higher the organic chlorine content of the higher.
