Micro-pore polarity induction absorbent for regeneration treatment on electric power oil and preparation method of micro-pore polarity induction absorbent

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...

AI Technical Summary

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 exchange, and can only exchange a small part of acid radical ions or metal ions in the deteriorated oil, but has no adsorption effect on most polar molecular compounds produced after oil quality deterioration, and the ion exchange principle It has been widely used in water treatment technology for a long time. The activity of ions in water is much greater than that in oil. Therefore, the role of ion exchange resin in the field of power oil regeneration treatment is also greatly limited.
