Definitions
- the invention relates to a process for the regeneration of a catalyst in a reactor, which is equipped with at least one burner, as well as a device for carrying out the method.
- the catalytic conversion of the hydrocarbon-containing feed into the desired olefin products proceeds under heat absorption (endothermic).
- endothermic In order to maintain the temperatures required for an endothermic catalytic reaction in a reactor, it is usually provided with one or more burners.
- the catalytic reaction usually by-products, such as. As carbon, which precipitate on the catalyst and disable it. For this reason, the catalyst has to be regenerated, for which the supply of starting materials is interrupted in a batch process and, for example, oxidizing gas is passed over the catalyst (see H. Bölt, F. Walser, Linde Reports on Science and Technology 49, 3-8 (1991)).
- the burners of the reactor are kept at minimum load (German Patent, DE 34 39 166). This can lead to the occurrence of temperature peaks, which can irreparably damage the catalyst. This leads to a reduction of the catalyst activity and thus to a reduction of the product yield in the catalysis cycle along with a reduction of the catalyst lifetime.
- This object is achieved in that the burners are turned off during the regeneration phase of the catalyst.
- the burners switched off are re-ignited after the regeneration phase via at least one pilot burner.
- the flame of the pilot burner and the burner is monitored.
- An adaptation of the heat output of the pilot burner to compensate for heat losses of the reactor is also appropriate.
- the deactivated burners are activated again by means of electronic ignition. On the device side, this object is achieved in that the burners have a shut-off device in the reactor.
- the reactor is expediently equipped with at least one pilot burner as well as with a pilot burner monitoring device and the burners.
- a means for controlling the performance of the pilot burner is also useful.
- the device contains a device for the electronic reignition of the burner.
