| Abstract: | A study is carried out for the extraction residue from the supercritical methanolysis of lignite through proximate analysis, elemental analysis, ash composition analysis and calorific analysis. The results show that the water content of extraction residue from the methanolysis of lignite is 6.93%-11.35%, ash content is up to 22.10%-24.46% and volatile matter is 39.75%-45.53%. The extraction residue from the methanolysis of lignite has no caking and coking properties and its carbon content is 66.74%-76.03% ; its hydrogen content is 4.51%-5.06%; its nitrogen content is 0.95%-0.99%; its sulfur content is 2.10%-2.57% and its oxygen content is 15.79%-25.13%; the C/H atomic ratios of extraction residue from methandysis of lignite are in the range from 1.214 to 1.302. The ash component of the extraction residue from the methanolysis of lignite contains mainly SiO2, A12O3, CaO and Fe2O3, in which SiO2 content is up to 47%-54%. The calorific value of the extraction residue from the methanolysis of lignite is 20.21 -22.65MJ/kg. Key words： Lignite Supercritical methanolysis Extract Composition analysis |
