摘　　要：在室温常压下,通过对两种变质程度不同的烟煤进行CS2/NMP混合溶剂萃取和反萃取,制备出两种棕褐色的精煤颗粒,并用透射电子显微镜(TEM)和红外光谱(FTIR)对其结构进行表征,结果表明:两种精煤颗粒超细微,粒径达到纳米级;颗粒近乎无灰,主要基团为脂肪族、醌基与芳酮、酚醇醚及取代芳烃。Two different rank soft coals were extracted and reverse extracted with carbon disulfied and N-melthy-2-pyrolidinone (CS2/NMP) mixed solvent at mild conditions,room temperature and normal atmosphere to prepare two kinds of brown particles of ultra-pure coal. The structures of the particles were characterized by TEM and FTIR. The results show that two kinds of nanometer particles of ultra-pure coal are superfine and there are almost no ash and a majority of organic group which include aliphatic,quinones,aryl,ketones,phenols,alcohols,ethers and substituted aromatics.
