Title:
USE OF JANUS CERAMIC MEMBRANE IN DISPERSION-STRENGTHENED GAS DISTRIBUTION PROCESS AND PREPARATION METHOD FOR JANUS CERAMIC MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2024/021145
Kind Code:
A1
Abstract:
The use of a Janus ceramic membrane in a dispersion-strengthened gas distribution process and a preparation method for the Janus ceramic membrane. The Janus ceramic membrane uses an Al2O3 ceramic membrane as a base membrane; and a hydrophobic group is grafted onto the base membrane in situ by means of a perfluoroalkyl silane impregnation method to prepare a hydrophobic ceramic membrane, and same is then subjected to single-side asymmetric surface deposition of a hydrophilic coating PDA by using dopamine, so as to prepare a Janus ceramic membrane for gas distribution. The Janus ceramic membrane has asymmetric wettability, not only has the specific properties of a hydrophilic ceramic membrane and a hydrophobic ceramic membrane, but can also ameliorate defects of the two membranes and generate a synergistic effect, and improves the gas distribution performance of the membranes during a gas-liquid dispersion process.
