AI Technical Summary
⚠Technical Problem
Existing absorbents have low absorption capacity for volatile organic compounds (VOCs), making it difficult to effectively treat VOCs in waste gas.
⚗Method used
A solubilizing composition, comprising a polyoxyethylene nonionic surfactant and paeonol, is used to form large-diameter micelles that bind fluorocarbons and hydrocarbon surfactants, reducing surface tension and increasing the solubility of the absorbent in toluene.
🎯Benefits of technology
It significantly improves the absorption capacity of the absorbent for toluene, especially in the middle and later stages. The synergistic effect of the solubilizing composition enables the absorbent to absorb more than 158.5 mg/g of toluene, making it suitable for industrial waste gas treatment.

Abstract
The application relates to the field of contaminated gas treatment, and particularly discloses a high-absorption VOCs absorbent and a preparation method thereof. The high-absorption VOCs absorbent comprises the following components in parts by weight: a solubilizing composition 20-30%; a cosurfactant 10-15%; solvent oil 40-50%; and water in the remainder. The solubilizing composition comprises component A, wherein the component A comprises polyoxyethylene nonionic surfactant and paeonol, and the weight ratio of the polyoxyethylene nonionic surfactant to the paeonol is 1: (0.1-0.2). The high-absorption VOCs absorbent and the preparation method thereof comprise the following steps: S1, uniformly mixing the solubilizing composition and the cosurfactant, adding water, and dropwise adding solvent oil to obtain the high-absorption VOCs absorbent. The high-absorption VOCs absorbent can be used for industrial absorption of solvents in waste gas, has the advantages of high absorption rate and an absorption amount of 141.5-145.7 mg / g after 50 hours of ventilation, and the preparation method has the advantages of few steps, simplicity and high efficiency.
