Catalytic wet oxidation catalyst and preparation method thereof.

Abstract

The invention discloses a catalytic wet oxidation catalyst and a preparation method thereof. The catalyst comprises the following core-shell structure components, the core-shell structure components take active carbon loaded with transition metal as a core, and take alumina containing rare earth metal or amorphous silicon-aluminum as a shell. The method is characterized in that during a gel forming process of alumina or amorphous silicon-aluminum and a rare earth metal compound, an active carbon slurry loaded with transition metal is introduced, and after the gel forming process, the catalyst can be obtained through an aging process. The catalyst has high reaction activity and usage stability.

Description

technical field [0001] The invention relates to a catalytic wet oxidation catalyst and a preparation method thereof, in particular to a catalytic wet oxidation catalyst containing active carbon and alumina or amorphous silicon aluminum and a preparation method thereof. Background technique [0002] With the increasingly stringent global environmental protection regulations, the control indicators for sewage discharge standards are getting higher and higher. Under this form, wastewater catalytic oxidation treatment methods have been paid more and more attention to and adopted by people, such as the catalytic wet method of high-concentration sewage Oxidation, electrolytic catalytic oxidation, photocatalytic oxidation, advanced oxidation, etc. In the process of catalytic oxidation of wastewater, in order to obtain the ideal treatment effect and keep the cost of wastewater treatment low by reducing the reaction temperature and pressure, the preparation of cheap catalysts with hi...
