摘要：
The pyrolysis characteristics of lignite with low ash were investigated and the influences of heating rate on the weight loss process were also discussed. The results showed the lignite pyrolysis process can be divided into three stages, in which the second stage, the temperature range is about 300 degrees C similar to 550 degrees C, is the main process of the weight loss; with the heating rate is enhanced, the temperature of maximum rate of weight loss was increased while the maximum rate of coal weight loss is increased, and the temperature of maximum rate of coal weight loss is basically the same.
