【摘要】 <正> 页岩油生产过程中的动力学研究,已有半个多世纪的历史了。近几年来,随着干酪根成油学说的发展,为了揭示成烃机理,关于油页岩和生油岩干酪根热降解反应动力学的研究,引起了许多石油地球化学工作者的极大兴趣。 国外对某些油页岩热解动力学参数的测定结果是,热解过程近似一级反应,表观活化能约为13—52.5 kcal/mol;国内华东石油学院王庭芬等用差热分析测定了两个含更多还原

【Abstract】 The kinetic features of thermo-degradation of kerogen in unmatured oil shales and low-rank coals are studied by means of thermogravimetric analysis. The study indicates that there is no unitary reaction order and the apparent activation energy varies also in the entire process of the thermo-dagradation. The maturing process of kerogen can be ascribed to zero-order reaction and has lower average apparent activation energy; the oil generation process of matured kerogen can be ascribed to first-order reaction and has higher average apparent activation energy. The relation between the kerogen types and average apparent activation energies in maturing process can be given as E_Ⅲ>E_Ⅱ>E_Ⅰ; while in oil generation process as E_Ⅰ>E_Ⅱ>E_Ⅲ.更多还原
