苯胺催化剂再生与活化方法的探讨

阐述了生产苯胺用催化剂常用的再生与活化方法，同时介绍了其他新的再生与活化方法，即在爆炸极限之外，用廉价的二气回收气或变压吸附所产生的“废气”等其他气体对催化剂进行再生与活化。认为采用“废气”对催化剂进行再生与活化，可从一定程度上降低生产成本。

Exploration on New Regeneration and Activation Method for Catalyst in Producing Aniline

In this article common regeneration and activation methods for catalysts in process of producing aniline were expounded, and a new method was also introduced. In this new method using cheap recovery gases of two kinds from synthetic ammonia completes the generation and activation, and the ground is given by terms of theory. With the use of the method, the production cost is reduced to a certain extent. To a new built unit, millions of equipment investment is thus saved.
