A series of char samples were derived from pyrolysis of two typical low-rank coals in China (Shengli lignite and Shenmu bituminous coal) at low, medium and fast heating rates, respectively, to the same pyrolysis temperature 750 °C. Then these chars were characterized by means of thermogravimetric an...
