摘要：

通过工业分析、元素分析、灰成分分析和热值分析对褐煤超临界醇解萃余物进行了研究，结果表明，褐煤醇解萃余物水分含量为6.93%～11.35%，灰分含量高达22.10%～24.46%，挥发分为39.75%～45.53%，无黏结性和结焦性；褐煤醇解萃余物碳含量为66.74%～76.03%，氢含量为4.51%～5.06%，氮含量为0.95%～0.99%，硫含量为2.10%～2.57%，氧含量为15.79%～25.13%，C/H原子比为1.214～1.302；褐煤醇解萃余物灰成分主要含有SiO2、Al2O3、CaO和Fe2O3，其中SiO2含量高达47%～54%；褐煤醇解萃余物的热值为20.21～22.65MJ/kg。

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, Al2O3, 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.
