In an aspect, the rejuvenation process comprises contacting a deactivated catalyst comprising at least one Group 10 metal and a microporous crystalline metallosilicate with an oxygen-containing gaseous stream under conditions comprising a temperature ranging from about 250° C. to about 375° C. and a pressure of up to about 100 bar. In a further aspect, the rejuvenation process comprises contacting a deactivated catalyst comprising at least one Group 10 metal, at least one rare earth metal, and a microporous crystalline metallosilicate with an oxygen-containing gaseous stream under conditions comprising a temperature ranging from about 250° C. to about 500° C. and a pressure of up to about 100 bar.

摘要： A process is presented for the dehydrogenation of paraffins. The process utilizes heated air for the combustion of a fuel within the dehydrogenation reactor to provide the heat of reaction for oxidative dehydrogenation. The nitrogen in the air is utilized as a diluent. A paraffin feedstream is mixed with a fuel, and the fuel/paraffin feedstream is mixed with an oxidant air stream at the inlet of dehydrogenation reactor.
