煤热解过程中氮、硫析出形态的研究进展

综述了煤中氮、硫元素的赋存形态及其在煤热解过程中析出形态的研究进展 ,讨论了温度、压力和煤阶等因素对氮、硫在热解产物中赋存形态的影响 ,同时给出了一些含氮、硫化合物的可能生成途径。指出应大力加强煤热解过程中氮、硫析出形态的研究 ,以实现煤的洁净利用 Research advancement of nitrogen and sulfur existence form in coal and separated out form of them in coal pyrolysis process are summarized in this paper. Effect of temperature, pressure and coal rank on the existence form of nitrogen, sulfur in the pyrolysis products was discussed. The probable formation paths of nitrogen and sulfur compounds were provided. The emphasis is laid on basic research of nitrogen and sulfur forms in pyrolysis process for realized the clean use of coal
