Finding a suitable inorganic membrane is one of the critical issues, which needs to be explored for CO2/H2 separation. In the present study, Ba-SAPO-34 zeolite membrane was synthesized and followed by a modification process. CO2/H2 separation of the membrane was investigated by varying the independent process variables (CO2 in the feed, pressure difference across the membrane and temperature). Modeling and optimization for the responses (CO2/H2 separation selectivity and CO2 permeance) was performed by applying response surface methodology and central composite design, which is available in Design Expert software. The accuracy of the models in predicting the response was tested by comparing with the experimental value of response and the two values were in good agreement. The optimization of the models gave CO2 permeance of 19.23 � 10�7 mol/m2 s Pa and CO2/H2 separation selectivity of 11.6 at 5 CO2 in the feed, a pressure difference of 100 kPa, and temperature of 30 °C for Ba-SAPO-34 zeolite membrane. © 2022 by the authors. date: 2022 publisher: MDPI official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85138706019&doi=10.3390%2fmembranes12090850&partnerID=40&md5=3d1efb41f9834645df5593521eddfe4f id_number: 10.3390/membranes12090850 full_text_status: none publication: Membranes volume: 12 number: 9 refereed: TRUE issn: 20770375 citation: Ng, T.Y.S. and Viriya, V. and Chew, T.L. and Yeong, Y.F. and Ahmad, A.L. and Ho, C.-D. and Jawad, Z.A.
