The affects of coal rank and temperature on the yield of pyrolysis gaseous products and sulfur distributions were studied.

利用固定床热解装置对3种不同煤种进行了热解研究,考察了温度和煤的性质对热解气态产物以及硫元素逸出规律的影响,结果表明:除了煤的性质外,温度是影响热解产物分布的重要影响因素;同时CO和CO2的逸出量与煤中氧元素的含量有关,而生成CH4和气态烃的量与H/O原子比有很大关系;热解过程中含硫物质以H2S和少量COS的方式逸出到气相,而逸出的气态硫也与煤的含硫量有直接关系。
