摘要
以热重法(TG)评价了大庆减压渣油四组分和八组分(饱和烃、轻芳烃、中芳烃、重芳烃、轻胶质、中胶质、硬胶质和沥青质)的热转化反应性能。按一级反应动力学方程计算了各组分的热转化动力学参数。根据相应组分动力学参数的差异,提出在研究残渣油复杂反应动力学时,可将残渣油分成饱和烃、轻芳烃+中芳烃、重芳烃、软胶质(轻胶质+中胶质)、硬胶质和沥青质六个集,总组分。
The Daqing vacuum residue(DQVR)was firely separated into eight-fractions in-stead of customary four-fractions.The eight-fractions were called saturates,light,middle andheavy aromaties,light,middle and heavy resins and asphltene. The four-fracions and eight-frac-tions of DQVR were thermal cracked in a thermogravimetric analyzer system. The parameters ofthermal reaction kinetics were obtained according to first-order equation. The parameters of lightarmotics were nearly the same as that of middle armotics,the parameters of light resins weren-early the same as that of middle resins. So,we can charaterize DQVR with only six lumpedspecies which were saturates,light aromatics(including original light and middle aromatics),heavy aromatics,light resins(including original light and middle resins),heavy resins and as-phltene and each species had nearly the same thermal conversion feature respectively.
