The Pyrolysis Gas Properties from Lignite

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 experiments was carried out on lignite;The paper also presents an analysis of the basic gas compositions 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 dynamic during the pyrolysis.
