Analysis on the Behavior of Pressurized Pyrolysis of Shengli Lignite
摘要
Abstract
In order to investigate the influence of pressure on the behavior of coal pyrolysis, the pressurized pyrolysis of Shengli lignite was carried out under high temperature pressurized thermogravimetric analyzer (PTGA) and the gas product released from the PTGA was detected online by the portable infrared gas analyzer, then the kinetic parameters were also calculated. Results show that coal pyrolysis under different pressure can be divided into three phases, with the increase of pyrolysis pressure, weight loss peak at the low-temperature phase shifts to higher temperature while that of the mid-temperature phase shifts to lower temperature, and the coal char yield is enhanced gradually, what's more, the yield of CO is improved and there is no obvious rule in CH4 release; the pyrolysis activation energy under different pressure is almost the same and has good kinetic compensation effect with the pre-exponential factor, the correlation coefficient is 0.982.关键词
