摘要

Abstract

SSZ-13 membranes with high separation performances were prepared using ball-milled nanosized seeds by once hydrothermal synthesis. Separation performances of SSZ-13 membranes in CO

/CH

and N

/CH

mixtures were enhanced after synthesis modification. Single-gas permeances of CO

and CH

and ideal selectivities were recorded through SSZ-13 membranes. The effects of temperature

pressure

feed flow rate and humidity on separation performance of the membranes were discussed. Three membranes prepared after synthesis modifications had an average CO

permeance of 1.16×10

(equal to 3554 GPU) with an average CO

/CH

selectivity of 213 in a 50 vol%/50 vol% CO

/CH

mixture. It suggests that membrane synthesis has a good reproducible. The membrane also displayed a N

permeance of 1.07×10

(equal to 320 GPU) with a N

selectivity of 13 for a 50 vol%/50 vol% N

mixture. SSZ-1

3 membrane displayed stable and good separation performance in the wet CO

/CH

mixture for a long test period over 100 h at 348 K. The current SSZ-13 membranes show great potentials for the simultaneous removals of CO

and N

in natural gas purification as a facile process suitable for industrial application.
