摘要

石油或芳烃的逆流加氢过程相比其并流加氢有很大的优势，可以达到深度的脱硫脱芳的目的。逆流加氢过程的重点和难点是研究反应器流体力学性能，解决液泛问题。目前，逆流反应器一般采用滴流床反应器为基础研究，改变催化剂的外在构造和布置不同的填料，改变其空隙率，或是设置规整的单独气、液通道，而优化其流体力学性能，实现逆流操作，其中代表性的反应器有Katapak规整填料反应器、IFM反应器和TLP反应器。虽然逆流反应器有其独特之处，但是局限和缺点依然较多，尚需对其继续研究。

Abstract：

The countercurrent hydrogenation process of petroleum or arene has greater advantages than cocurrent hydrogenation process, which can achieve deep desulfurization of the petroleum or arene. The emphasis and difficulty of countercurrent hydrogenation process are the study of hydrodynamic performance of reactor and the solution of flooding phenomenon of reactor. At present, the research of the countercurrent reactor mainly focuses on the following aspects: generally, the trickle bed reactor is the basic research; the shape of catalyst is changed， and the different fillers are arranged in order to improve the porosity of trickle bed； The separate gas and liquid channels are arranged regularly to optimize the hydrodynamic performance of the reactor and realize its countercurrent operation. Some representative reactors of the countercurrent hydrogenation includeKatapak structured packing, TLP reactor and the IFM reactor. The present countercurrent reactors have their own characteristics, but the limitations and demerits also remain. So the further study is needed.

Key words： hydrogenation process of petroleum countercurrent hydrogenation process countercurrent reactor flooding hydrodynamic performance
