Gas separation method
Amorphous silica porous membranes prepared by the sol-gel method are used to separate fluorocarbons by utilizing the molecular sieve effect. This solves the problem of low separation efficiency of fluorocarbons in existing technologies and achieves efficient separation of fluorocarbons and azeotropic mixtures.

AI Technical Summary
Existing technologies struggle to efficiently separate mixtures of fluorocarbons, especially due to the small differences in molecular diameters and the azeotropic phenomenon, which makes separation difficult. Furthermore, distillation methods have high energy loads, and membrane separation is ineffective.
A porous amorphous silica membrane formed by the sol-gel method is used to separate fluorocarbons by utilizing the molecular sieve effect. When a mixed gas is supplied, it passes through the porous membrane at specific temperature and pressure to achieve selective permeation of fluorocarbons.
It achieves efficient separation of fluorocarbons, especially azeotropic mixtures, reducing energy load and improving separation efficiency.
