A composite catalyst has been commercially used for the hydrocracking of Daqing heavy gas oil containing 50% of coking gas oil.The reaction mecha- nism on this composite catalyst has been studied,including: (1)Hydrocracking activities of composite catalyst of different blending ratios between catalyst 3762 and catalyst 12-46 were tested with a 100 ml hydrocra- cking reactor system.It was found that an optimum blending ratio exists, under which both the quality and the yield of the desired products are better than those obtained with each individual catalyst. (2)The apparent kinetics of hydrocracking reaction over the composite catalyst was studied.The rate constant and activation energy thus obtained are consistent with those in literatures. (3)Based on the experimental results and Lin's concept of the existence of both strong and weak active sites on hydrogenation catalyst,it is suggested that:(Ⅰ)The strong and weak active sites on catalyst 3762 are in the oppo- site to those on catalyst 12-46;(Ⅱ)The intermediate isomers formed on cata- lyst 12-46 are unstable and are easily adsorbed and cracked on catalyst 3762; and(Ⅲ)The active sites on the two catalyst components act separately and relate to each other by intermediates. (4)The reaction mechanism of coking gas oil over the composite hydrocra- cking catalyt was proposed and was demonstrated with reactions of the para- ffins and aromatics in coking gas oil.The existence of the optimum blending ratio of the composite catalyst as well as many phenomena occured in the com- mercial hydrocracking unit is explained.

本文对含焦化蜡油(50%)的大庆重瓦斯油在工业复合催化剂上加氢裂化的反应机理进行了研究。在100ml 加氢试验装置上试验了不同混合比的复合催化剂的加氢裂化活性,发现12-46和3762两种催化剂混合使用时,两者之间有一个最佳配比,使产品质量与产率均优于单一催化剂,并研究了前述焦化蜡油在复合催化剂上加氢裂化反应的表观动力学,求得的速率常数和活化能与文献值一致。应用林励吾提出的在加氢催化剂上可以同时存在强弱不同的两种活性中心的观点,我们提出;(1)在3762催化剂上的强活性中心和弱活性中心与在12-46催化剂上相反;(2)在12-46催化剂上生成的中间产物——异构化合物很不稳定,易为3762催化剂所吸附和裂化;(3)复合催化剂中两种催化剂上的活性中心在反应过程中各自独立起作用,并通过中间产物联系在一起.应用此三点假设,提出了焦化蜡油在复合催化剂上的反应机理,用焦化蜡油中的烷烃和芳烃为代表说明了其反应历程。同时还解释了复合催化剂存在最佳配比的原因,也解释了在生产过程中出现的许多现象.

Bench scale equilibrium flashing unit is used to simulate the commercial crude fractionator. Two-stage equilibrium flashings of Subei and Luning crude blends are performed under atmospheric pressure, 360C and vacuum (4kPa), 380C, respectively. The total vaporization rates are compared with the obtained by superposition method,and the op- timum blending ratio for the two crudes is thus determined. The results conform well with commercial operating data of the refinery of Jinling Petrochemical Corporation....

本文着重研究了采用常减压蒸馏平衡气化装置模拟炼油厂生产条件,分别在常压、360 C和减压(4kPa)、380 C进行两次平衡气化,求得常减压蒸馏总气化分率并与加和法求得的理论拔出率相比较,确定苏北原油与鲁宁管输原油最佳掺炼比,并测定其气相馏出物的馏程。与金陵石化公司炼油厂1990~1992年期间进行苏北原油与鲁宁管输原油掺炼生产的实际情况相比较,所得结论基本相符。

According to the operating data of production units, the Mending ratios of various crude oils to the Liaohe Crude were correlated with their physical properties by gradual regression analysis. These correlation formula can be used for the prediction of optimal blending ratio when processing various crude oils so as to enhance the distillation yields of atmospheric vacuum unit.

根据装置的生产操作数据,用逐步回归分析法求出各种外购原油与辽河原油的掺炼比与原油物性的关联式,用以预测掺炼不同原油时的最佳掺炼比,从而提高常减压蒸馏装置的拔出率.
