Study on Pyrolysis Characteristics and Pyrolysis Kinetics of Lignite

Experimental studies on the pyrolysis characteristics of Baiyinhua lignite were carried out by non-isothermal thermogravimetric analysis.The effects of the heating rate and particle size on pyrolysis characteristics of Baiyinhua lignite and the pyrolysis kinetics were analyzed.The results showed that the heating rate was the main influence factor of lignite pyrolysis,and the particle size also had a certain impact on lignite pyrolysis.Coats-Redfern integral method was used to determine the lignite pyrolysis kinetic parameters at low-temperature period.
