AI Technical Summary

Problems solved by technology

Supported liquid membranes have problems such as carrier loss, instability, and short life; fixed carrier membranes solve the problem of carrier loss, but because the carrier is fixed on the polymer membrane, the fluidity is poor, resulting in low permeability and selectivity

Embodiment 1

[0011] An aqueous solution containing 0.5wt% polyethylene glycol diacrylate, 5wt% polyethylene glycol acrylate, 0.5wt% tetraethylenepentamine, and 0.6wt% polyamide-amine dendrimer was prepared, and the aqueous solution, toluene and ethanol to form a microemulsion, adding 0.3wt% benzoyl peroxide (calculated by the mass of toluene) and reacting for 4 hours, then adding 30wt% of polysulfone (calculated by the mass of toluene). After the polysulfone is completely dissolved, defoaming. A flat film was scraped out from the polysulfone porous support film, and then placed in water to cure to form a film. Test after cleaning and drying. 25°C, 5 atm, CO 2 Flux is 25000GPU, CO 2 / O 2 The separation factor is 800.

Embodiment 2

[0013] An aqueous solution containing 0.3wt% pentaerythritol triacrylate, 5wt% polyethylene glycol acrylate, 0.5wt% tetraethylene pentamine, 0.5wt% Co (Salen) was prepared, and the aqueous solution, toluene and ethanol were prepared into a microemulsion, After adding 0.3 wt% of benzoyl peroxide (calculated by the mass of toluene) and reacting for 4 h, 35 wt% of polyethersulfone (calculated by the mass of toluene) was added. After the polyethersulfone is completely dissolved, defoaming. The mixed solution was used for spinning, and the final hollow fiber membrane was obtained at 25°C under 5 atm, O 2 Flux is 500GPU, O 2 / N 2 The separation factor is 40.

Embodiment 3

[0015] Prepare an aqueous solution containing 1wt% copper sulfate and 0.12wt% m-phenylenediamine, and configure the aqueous solution with n-hexane and isopropanol in a mass ratio of 0.3:0.25:0.45 to form a microemulsion; take a certain amount of trimesoyl chloride (microemulsion 0.1% of the mass of n-hexane) was dissolved in the microemulsion, and after 5 minutes of reaction, a certain amount of silicone rubber and its catalyst and cross-linking agent were put in, and after stirring evenly, it was casted to form a film. The final flat film was obtained at 25 °C, 5 atm, C 2 H 4 Flux is 1000GPU, C 2 H 4 / C 2 H 6 The separation factor is 800.

Description

technical field [0001] The invention relates to polymer technology, nanotechnology and membrane separation technology, in particular to a separation membrane with a function of promoting transfer. Background technique [0002] Membrane separation technology is one of the six major high-tech technologies in the world today, and has become an important high-tech and sustainable development technology for solving contemporary energy, resource and environmental pollution problems. The United States, Japan and other western developed countries have regarded membrane technology as a high-tech priority in the 21st century, and have been widely used in many fields such as material separation, concentration and purification. Due to issues such as global warming, energy conservation and emission reduction are urgent. Separation membrane technology has become a hot spot due to the advantages of low energy consumption. Separation membrane is the core of gas membrane separation technol...
