文摘
- •
Synthesis conditions were optimized for SAPO-34 membranes towards N2/CH4 separation.
- •
Membranes displayed N2 permeance as high as 1300 GPU and selectivity of 7.4.
- •
Membranes were highly reproducible.
- •
Membrane separation performance is superior to those of the state-of-the-art membranes.
- •
These SAPO-34 membranes have potential for economic N2 rejection in natural gas processing.
