Abstract
Zeolite-based membrane separation technology offers an efficient and sustainable solution to the separation and purification needs of modern industry. This review highlights advancements in zeolite membranes, focusing particularly on LTA, CHA, and DDR type small-pore zeolite membranes, as well as MFI type medium-pore zeolite membranes. Recent developments and innovations in membrane preparation technologies are first analyzed. Next, optimization strategies for zeolite membrane structures are summarized, emphasizing improvements in permeability, selectivity, and stability. These membranes demonstrate significant application potential in petrochemical processes, including hydrogen recovery, natural gas purification, carbon dioxide capture, hydrocarbon mixture separation, organic solvent dehydration, and membrane reactors. Finally, the challenges and opportunities associated with the synthesis and application of zeolite membranes are discussed, providing insights for future research directions.
