    From the experimental results,the phase diagrams,which correlate the temperature,pressure and percentage of vaporization of equilibrium flash vapori- zation of shale oil,are constructed.The focal point on the phase diagram of No.1 light gas oil of Fushun shale oil is 39.3 atm.(F_p)and 482℃(F_t);and that of Fushun crude shale oil is 30.1 atm.(F_p) and 558℃(F_t). The values of the focal points calculated by the empirical graph of Edmister show certain deviations from the experimental results,and these deviations will be larger if the empirical graph of Okamoto is used.But the theoretical methods of calculation developed by Katz and Brown or Edmister give much better results as compared with above empirical methods.Therefore,the theoretical method can be applied to calculate the data of equilibrium flash vaporization of shale oil and shale oil fractions.

    从实验得到了推算页岩油平衡汽化的温度-压力-汽化率的关系相图.抚顺页岩油一号轻油相图焦点为:F_p=39.3大气压,F_t=482°;抚顺页岩原油相图焦点为:F_p=30.1大气压,F_t=558°.应用 Edmister 的石油经验图所推算的平衡汽化率或相图焦点,与实验值是有一定偏差的.而用 Okamoto 的经验图推算的平衡汽化率则偏差更大。若以实沸点代表组成,应用实验的蒸汽压换算表求得平衡常数,然后进行抚顺页岩油一号轻油和抚顺页岩原油的平衡汽化率理论计算,则得到与实验值一致的结果;并且远较 Okamoto 或 Edmister 的经验方法好.因此,直接用理论方法来计算页岩油馏分或页岩原油的平衡汽化性质可以得到满意的结果.

    Using pure benzene as raw material for the evaluation of catalytic activity of MoS_2, the study of the poisoning effect of pyridine and the "nitrogen compounds" separated from diesel fraction of Shale oil on MoS_2 catalyst was carried out. The experiments show that when the MoS_2 catalyst is previously treated by pyridine or "nitrogen compounds" under high pressure at lower temperature(300℃), it loses its activity for the hydrogenation of benzene ring; while at higher temperature (420℃), in such case that the nitrogen compounds can be completely hydrogenalyzed, therefore, the hydrogenating activity of MoS_2 catalyst remains unchanged after nitrogen compounds treatment, however, its isomerization and cracking activities are somewhat poisoned. Among these the isomerization activity is more sensitive towards: nitrogen compounds. The results also show that the pgisoning effect of pyridine is analogohs to that of the "nitrogen compounds" of diesel fraction of shale oil.

    以苯作为評价MoS_2催化剂活性的原料,試驗了吡啶及頁岩油輕油“含氮化合物”对催化剂活性的影响。試驗証明在較低的溫度下(300°)經吡啶或“含氮化合物”的加氫处理后,催化剂完全失去了对苯加氫的活性;但在較高溫度下(420°以上),由于保証了含氮化合物的加氫裂解,催化剂仍保有相当的活性,其中除氫化性能几乎不受影响以外,影响最大的为异构性能,次之才为环烷的裂化性能。吡啶与含氮化合物的“毒性”,在性能上極其相近。
