| titleOfInvention | A kind of regeneration method of deactivated propane dehydrogenation catalyst |
| abstract | The invention relates to the field of catalysts, and in particular provides a method for regenerating a deactivated propane dehydrogenation catalyst, the method comprising: a) deactivating the dehydrogenation catalyst after the deactivation of the propane dehydrogenation reaction, first cooling the dehydrogenation catalyst in an inert gas atmosphere to a temperature of 300 ℃ ‑500℃, at this temperature, perform regeneration treatment in a weakly oxidizing gas atmosphere; b) then continue to cool down to 200‑300℃ in an inert gas atmosphere, at this temperature, under a Carry out regeneration treatment under the mixed gas atmosphere of at least two of them; c) after step b) finishes, replace described mixed gas with inert gas to inert atmosphere and drop to 50-100 ℃, at this temperature, in the presence of organic matter Carry out regeneration treatment; the dehydrogenation catalyst is a catalyst containing precious metals. The method of the invention can effectively restore the performance of the catalyst and improve the utilization rate of the catalyst. |
