褐煤低温热解气生成特性的研究

The Pyrolysis Gas Properties from Lignite

研究了褐煤进行低温热解时,热解温度对褐煤热解气相产物产量的影响规律;分析了不同热解温度下煤气的基本组成。结果表明,热解温度对煤气的产量、组成产生一定的影响。在300℃后,阶段煤气产量随热解温度的升高不断增大;煤气的成分随热解温度而发生变化。

In this paper, a research was carried out on the effect of pyrolysis temperature and holding time on the gas product yield of pyrolysis of lignite when low temperature pyrolysis ex- periments was carried out on lignite; The paper also presents an analysis of the basic gas compo- sitions under different pyrolysis temperature. The result shows that the yield and component of gas were influenced by the pyrolysis temperature. At the pyrolysis temperature above 300℃, the yield of staggered pyrolysis gas increased with temperature, while the component of gas was dy- namic during the pyrolysis.
