【摘要】 <正> 鲁奇加压气化焦油的产率一般在5%左右。关于其性质,国内外虽有些报道,但未见报道系统的组成分析。本文对沈北褐煤加压气化中间试验所产焦油的组成和性质进行了分析,并作了油品评价。1.实验方法将沈北褐煤加压气化焦油经精馏切割成<170%,170—230℃、230—270℃、270—更多还原

【Abstract】 A Lurgi gasifcation coal tar sample was separated into five fractionsof<170℃,170—230℃,230—270℃,270—330℃and>330℃ by fractional dis-tillation.Their compositions were analyzed by gas-liquid chromatographycoupled with mass spectrometer,fluorecent spectrometry,and(or)liquid-solid chromatography.The tar is an extremely complex mixture of organic compounds.Twohundred species of compounds have been detected in distillates of<330℃,ofwhich 77 species are aromatic hydrocarbons,48 species are paraffines,31species are olefines,29 species are oxygen-containing compounds,12 speciesare nitrogen containing compounds and 3 species are sulfur-containingcompounds.The distribution of compounds is too dispersed to be concen-trated and refined into pure products.Therefore,these fractions can pro-bably only be used as solvent or fuel oil.更多还原
