摘要： The present invention pertains to a process for regenerating and rejuvenating an additive-based hydrotreating catalyst containing Group VIB and Group VIII hydrogenation metals. The process comprises the steps of regenerating the catalyst by contacting it with an oxygen-containing gas at a maximum temperature of 500° C., followed by rejuvenating the catalyst by contacting it with an organic additive comprising an organic compound, other than a compound that the catalyst is contacted with in the course of its use as a catalyst prior to regeneration and rejuvenation. The organic additive is incorporated into the catalyst. If necessary, the catalyst may then be dried at such a temperature that at least 50% of the additive is maintained in the catalyst. The process according to the invention makes it possible to restore the activity of a used additive-based hydrotreating catalyst to its original level, or even to improve it to above that level.

摘要： The present invention pertains to a process for regenerating a used additive-based catalyst comprising the step of regenerating the catalyst by contacting it with an oxygen-containing gas at a maximum temperature of 500° C. Preferably, the maximum catalyst temperature during the regeneration step is 300-500° C., more preferably 320-475° C., even more preferably 350-425° C. The regenerated additive-based catalyst obtained with the process according to the invention has a higher activity than an additive-based catalyst regenerated at a higher temperature. Additionally, its activity is also higher than that of a corresponding catalyst, which never contained an additive.

摘要翻译： 本发明涉及再生使用的添加剂型催化剂的方法，其包括通过使催化剂与最高温度为500℃的含氧气体接触来再生催化剂的步骤。优选地，再生步骤期间的最大催化剂温度 为300-500℃，更优选为320-475℃，甚至更优选为350-425℃。用本发明方法获得的再生添加剂基催化剂具有比添加剂催化剂更高的活性 在较高温度下再生。 另外，其活性也高于不含有添加剂的相应催化剂的活性。
