Problems solved by technology

[0009] Disadvantage 1: The adsorption medium has a large pore size, the adsorption capacity of the degraded products is small, and the types of degraded products adsorbed are limited
The larger the pore size, the smaller the adsorption capacity and the poor adsorption effect
[0013] Disadvantage 2: The adsorption force of the adsorbent is small, and the adsorption is non-polar, resulting in poor oil regeneration effect
The ion exchange resin treats the oil through the principle of ion exc

Embodiment 1

[0044] The cetyltrimethylammonium bromide of 36.4g is dissolved in the aqueous ethanol solution of 300ml (Wt 乙醇 =20%), adjust the pH value of the solution to 11 with ammonia water to obtain an alkaline solution; take 57.6g of SiO 2 2H 2 O and 85.8g of Al(OH) 3 Dissolve in the above alkaline solution in a water bath at 60°C, stir for 10 hours, and the speed of the stirring paddle is 800 r / min; after the solution is evenly stirred, add 0.5 g of elemental boron, and continue stirring for 10 hours. After the boron doping is uniform, the solution is moved into a stainless steel autoclave lined with polytetrafluoroethylene, distilled water is added, the water level is controlled at 80% of the height of the reactor, and the constant temperature of the blast drying oven is controlled at 150°C, and the hydrothermal reaction is carried out for 18 hours , A white gel-like substance was obtained after the reaction. Wash the white gel-like substance and place it in a tubular heating fur...

Embodiment 2

[0050] 48.2g of cetyltrimethylammonium chloride was dissolved in 400ml of deionized water, and the pH value of the solution was adjusted to 10 with sodium bicarbonate to obtain an alkaline solution; 70g of tetraethyl orthosilicate and 51.4g of Al 2 o 3 Dissolve in the above alkaline solution in a water bath at 80°C and stir for 15 hours at a stirring speed of 1200r / min; add 0.68g of elemental boron to the solution and continue stirring for 10 hours; transfer the mixed solution into a high-pressure reactor, Control the constant temperature of the blast drying oven at 180° C., and carry out the hydrothermal reaction for 24 hours. After the reaction, a white gel-like substance is obtained. The white gel was repeatedly washed with ethanol and deionized water, and then calcined in a muffle furnace at 800°C for 6 hours to obtain a white blocky solid. Control the temperature of the muffle furnace at 1700°C to melt the white blocky solid. Add 41g of graphite to the liquid and dispers...

Embodiment 3

[0055] Dissolve 28.5g of cetyltrimethylammonium bromide and 19.4g of octadecyltrimethylammonium chloride in 500ml of deionized water, adjust the pH value of the solution to 8 with glacial acetic acid; add 170g of kaolin, at 70°C Stir in a water bath for 24 hours, the stirring speed is controlled at 1500r / min; add 0.8g elemental boron to the mixed solution, and continue to stir for 10 hours; move the boron-doped mixed solution into the reaction kettle, control the temperature at 220°C, and adjust the water volume in the reaction kettle To normal, carry out hydrothermal reaction for 36h; wash the white gel after hydrothermal reaction with absolute ethanol and deionized water successively, control the temperature of the tubular heating furnace at 800°C, and calcinate the white gel for 10h, The obtained white solid calcined product is then heated and melted in a muffle furnace at 1600°C, and 37g of graphite is added to the molten liquid to make holes. Carry out secondary calcinati...

Abstract

The invention discloses a micro-pore polarity induction absorbent for regeneration treatment on electric power oil and a preparation method of the micro-pore polarity induction absorbent. The absorbent comprises the following components: Si, Al and B, wherein the mole ratio of Si to Al to B is (5-14):(8-20):1; the molecule aperture of the absorbent is 8 Angstrom-10 Angstrom; the specific surface area of the molecular aperture of the absorbent is 530m<2>/g to 650m<2>/g; and the absorbent has a micropore molecular structure. The preparation method comprises the following steps: dissolving quaternary ammonium salt into distilled water or an ethanol solution according to a ratio, adding a silicon source and an aluminum source according to a ratio, stirring in water bath, further adding elementary-substance boron, moving the solution into a high-pressure reaction kettle, carrying out hydrothermal reaction so as to obtain a white gel substance, washing the white gel substance and subsequently calcining, heating and melting the obtained white solid substance, adding a pore-making agent, after the molten liquid is cooled to be the room temperature, calcining and putting into a strong-magnetic field environment to be polarized, and finally carrying out induction and activation so as to obtain the absorbent. The absorbent has a micropore aperture and is large in specific surface area and high in molecular polarity and activity, and the absorption capacity and the absorption velocity on polar molecular compounds of degraded oil are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of adsorbents for regeneration treatment of electric power oil, and in particular relates to a microporous polarity-inducing adsorbent for regeneration treatment of electric power oil and a preparation method thereof. Background technique [0002] Turbine oil, anti-fuel oil, transformer oil and various auxiliary engine oils used by power generation and transmission enterprises play the roles of lubrication, cooling, speed regulation, insulation, arc extinguishing, etc. during operation. Whether the electrical equipment can operate safely and normally. Affected by system working conditions such as oxygen, temperature, moisture, radiation, light, electric (magnetic) field, metal catalysis and other external factors, the power oil will deteriorate during operation, which not only affects the service life of the oil itself, but also It also poses a great threat to the safe and stable operation of power generati...
