摘要：
Different chemical and petrographical methods were earlier proposed for the prediction of coal liquefaction. Thermogravimetric studies (DTG, TG) of coals were now performed and the same coals were liquefied. A good correlation was found between DELTAA(max) (the main decomposition area during the maximum rate of decomposition in DTG) and Sk (the degree of conversion of organic substances during coal liquefaction). DELTAA(max) measurement may be a good, quick and quite reliable method for the prediction of coal liquefaction, which needs to be standardized.
