The changes in the gaseous and wastewater products obtained from hydrothermally treated lignite were investigated. Gaseous and wastewater products were characterized by gas chromatography and total organic carbon (TOC) analyzer, inductively coupled plasma atomic emission spectroscopy, and high performance liquid chromatography (HPLC), respectively. The results showed that TOC value began to apparently increase at the temperature of 200 °C, when CO2 started to be detected. The detection of CO2 is due to decarboxylation. Glucose, xylose, glyceraldehydes, and levulinic acid were detected by HPLC. Moreover, the total amounts of monovalent cations (Na+ and K+) in wastewater increased markedly from 100 to 150 oC and then changed slight with increasing temperature. The total amount of divalent cation Mg2+ in wastewater increased greatly up to 200 oC then changed little with increasing temperature, and the total amount of divalent cation Ca2+ increased apparently up to 250 oC.
