摘要:
从煤/油加氢共炼副产物中分离出沥青质,采用元素分析、X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、核磁共振(1H-NMR)等仪器对沥青质的化学组成、晶体结构、结构参数和官能团进行了表征。结果表明:煤/油共炼沥青质中含有质量分数为9.36%的氧元素,以醇、酚、苯氧基等官能团形式存在,羧酸的相对摩尔分数为2.17%;沥青质的片层数、片层环数与煤基沥青烯相近,但是,低于石油基沥青质;沥青质基本结构以稠环芳烃为主,缩合方式以渺位缩合和迫位缩合为主,桥键结构少,外围含有少量环烷烃和短侧链取代基。
Abstract:
The asphaltene was obtained from coal-oil co-processing product.The properties of the asphaltene such as chemical composition,structure parameters,crystal structure and functional group were analyzed by elemental analysis,X-ray diffraction,Fourier transform infrared spectrometer,1H-nuclear magnetic resonance.The results showed that the mass fraction of the oxygen element was contained at 9.36% in the asphaltene.Oxygen element mainly existed in the form of functional group of alcohol hydroxyl,phenol hydroxyl,phenoxy,carbonyl,the relative mole fraction of carboxylic acid functional group was only 2.17%.The lamellar number and lamellar ring number of the asphaltene were closer to the coal-based asphaltene,and lower than that of petroleum based asphaltene;the basic structural unit of the asphaltene took polycyclic aromatic hydrocarbons as the core structure,the condensation mode was mainly steric condensation and forced condensation,the bridge bond structure was few,and the periphery contained a small amount of cycloalkanes and short side chain substituents.
