Abstract
The invention relates to a method and a device for the controlled regeneration of a catalyst and of a fired reactor, especially a catalyst and a reactor in a plant for producing olefins from a hydrocarbon-containing charge. During the regeneration phase of the catalyst for recovering the catalytic activity, the burners of the reactor are switched off. After the regeneration phase, the burners are re-ignited by means of inbuilt pilot burners. The pilot burners are monitored and their capacity is adjusted in such a manner that the heat loss of the reactor during the regeneration phase of the catalyst is compensated for.
Description
The present invention relates to a kind of in being equipped with the reactor of at least one burner the method for regenerated catalyst, and the device of implementing this method.
Preparing from hydrocarbonaceous feed the equipment of alkene, hydrocarbonaceous feed is being catalytically conveted to desired olefin product need absorbs heat (heat absorption) and carry out.In order to keep the necessary temperature of endothermic catalytic reaction in the reactor, this reactor is equipped with one or more burners usually.Usually can generate accessory substance in the catalytic reaction process,, and be deposited on and make its inactivation on the catalyst as carbon.Given this reason must will be interrupted the introducing of raw material with catalyst regeneration for this reason in discontinuous method, and for example need make oxidizing gas pass through catalyst (to see H.
, F.Walser, Linde Reports on Science Technology49,3-8 (1991)).According to prior art, during this process, the burner of reactor remains on minimum load (German patent DE 34 39 166).Temperature peak can occur at this, these temperature peaks will destroy catalyst irretrievablely.This causes catalyst activity to reduce, and therefore causes the product yield in the catalysis cycle to reduce, and life of catalyst is reduced.
An object of the present invention is the device that designs a kind of method of the above-mentioned type and implement this method, thereby avoid or unacceptable high temperature peak of minimized appearance and the catalyst breakage that thereupon occurs.
According to the present invention, this purpose is achieved by closing burner in the catalyst regeneration stage.
In a particularly preferred embodiment according to the invention, the burner of cutting out can use at least one pilot light to light a fire again after the regeneration stage.Advantageously the flame of pilot light and the flame of burner are monitored.Export the heat loss of compensatory reaction device equally also advantageously by the heat of regulating pilot light.
In another embodiment of the invention, the burner of cutting out activates again by electronic ignition.
With regard to device, the burner of cutting out device by band in the reactor reaches desired destination.
Advantageously reactor is equipped with at least one pilot light, and the same monitoring device that is used for pilot light and burner that is equipped with.Control the device of pilot light power also advantageously.In another embodiment of the present invention, this device comprises and is used for the device that the burner electronics is lighted a fire again.
Especially, the present invention can avoid occurring unacceptable high temperature peak and thing followed catalyst breakage in the catalyst regeneration stage burning reactor, and improves life of catalyst.
