Embodiment 1

[0050] Solid aluminum chloride was added to distilled water while heating and stirring until dissolved to obtain solution (a). Add an appropriate amount of distilled water to the concentrated ammonia water and dilute it into about 10wt% dilute ammonia water (b). Add the powdered coconut shell charcoal to the glucose aqueous solution and mix evenly, the liquid-solid volume ratio is 3:1, then add water and make a slurry to obtain the slurry (c). After adding (a) into the gelling tank and stirring and heating to 60°C, open the valve of the container containing (b), and control the system in the tank to drop to pH=4.0 within 10 minutes, then add (c), continue to add (b) dropwise, and control the dropwise addition of the tank system to pH=8.0 within 30 minutes. Keep the temperature at 60°C, pH=8.0, age for 1 hour, filter the material in the tank, wash until there is no chloride ion, filter, dry the filter cake at 110°C for 10 hours to obtain carrier material A-1, and then Calcine...

Abstract

The invention discloses a catalyst carrier material, a catalyst carrier and a preparation method thereof. The catalyst carrier material uses activated carbon as a core and alumina dried gum as a shell. The preparation method comprises the following steps: introducing activated carbon slurry into the process of gelling amorphous alumina; aging, molding, and drying to obtain the carrier material; molding or un-molding to prepare the carrier. According to the catalyst prepared from the catalyst carrier material or carrier, a reactant firstly contacts and reacts with the alumina serving as the shell layer, and is contacted with the activated carbon serving as the core layer to react, so that the advantages of alumina and activated carbon can be sufficiently utilized, the catalyst has relatively high reaction activity and using stability, and the service life of the catalyst can be prolonged.

Description

technical field [0001] The invention relates to a catalyst carrier material, a catalyst carrier and a preparation method thereof, in particular to a carrier material for catalytic wet oxidation catalysts, a catalyst carrier 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 high active co...
