Beschreibung
Zusammenfassung:	The invention discloses a recycled olefin isomerization method. The recycled olefin isomerization method comprises the following steps: firstly, pressurizing and heating a to-be-regenerated isomerizing reactor with nitrogen; blowing a lot of hydrocarbon compounds which are attached to a catalyst to a torch; and after a catalyst bed rises to the appointed temperature, beginning to add air, and avoiding temperature runaway by controlling the oxygen content in the combustion process. A relatively stable operation of a device is achieved by using the difference in conversion rate and selectivity of the catalyst at the initial stage and the final stage; the circulation volume of butane in feeding reaction is reduced; and meanwhile, the energy consumption of the device is lowered.
