NF/RO faujasite zeolite membrane-ammonia absorption solvent hybrid system for potential post-combustion CO2 capture application

▶ A novel post-combustion CO2 capture technology based on absorption solvent-NF/RO FAU membrane hybrid process was developed. ▶ FAU-type zeolite membranes were prepared by a new method. ▶ FAU membranes prepared with an SDA had better separation performance than those prepared without an SDA. ▶ The calcination step was unnecessary for the membranes developed in this study. ▶ FAU membrane elements behaved efficiently as an H2O- and NH4OH-transporting, but total carbon species-rejecting separator.
