Carbon deposit cleaning agent and its application in reproduction process of carbon deposit deactivation catalyst

Abstract

The invention discloses a carbon build-up cleaning agent and its use in the regeneration process of devitalized catalyst, the carbon build-up cleaning agent comprises the following components: ethanolamine 5-95 v%, ethyl ether 5-95 v%, butanol 0-90 v%, phenol 0-90 v%. The carbon build-up cleaning agent can be used for catalysts with appreciable heat release during regeneration, especially for devitalized hydrogenation catalyst and methane aromatization catalyst requiring oxidation burning-out for carbon build-up cleaning.

Description

technical field

[0001] The invention relates to a carbon deposit cleaning agent and its application in the regeneration process of deactivated catalysts, especially suitable for the regeneration of deactivated hydrogenation catalysts. Background technique

[0002] Catalysts used in refining and chemical processes will gradually lose their activity during long-term operation. The reason is largely due to the deposition of carbon deposits on the surface of the catalyst. These coke-deactivated catalysts are regenerated by oxidizing and burning off the coke, and the activity can be partially or completely restored, and they can still be used in industrial production. Some catalysts can even be regenerated multiple times to achieve the purpose of saving energy and increasing benefits.

[0003] When the carbon deposition deactivation catalyst is regenerated by burning carbon, the carbon deposition will react with oxygen and be removed, and a large amount of heat will be generated...
