鸡西煤制磺化煤的研究
Research on preparing sulphonated coal using lignite char
用褐煤半焦制备磺化煤的研究
The result shows that the carbocoal produced by modified lignite under low temperature pyrolysis is a good raw material for preparing sulphonated coal ; the quality of raw materials and the temperature are the most important factors affecting the products
结果表明：褐煤低温热解改质后的半焦是生产磺化煤的优质原料，其原料性质和磺化温度是磺化煤质量的重要的影响因素。
Aiming at the problems of being easy in peroxidation and low in mechanical strength in preparing sulphonated coal with lignite , feasibility of producing the sulphonated coal with lignite being pyrolyzed in low temperature and the influence of the factors such as the property of raw materials , the temperature , the time , and the size of materials on the quality of sulphonated coals were studied
摘要针对褐煤生产磺化煤存在的容易过氧化和机械强度差的问题，用正交实验法研究了褐煤经低温热解改质后的褐煤半焦生产磺化煤的可行性及原料性质、磺化温度、磺化时间、原料粒度等因素对所生产磺化煤质量的影响。
