摘要: Abstract In this work, the incorporation of ZIF-8 nanofiller for improvement transport properties 6FDA-durene membrane in CO 2 /CH 4 separation is investigated. Central composite design (CCD) coupled with response surface methodology (RSM) were utilized optimization process variables over ZIF-8/6FDA-durene MMM separation. Three models correlating independent parameters including, pressure (3.5–12.5 bar), temperature (30–50 °C) and concentration (10–90 vol%) responses permeability, CH permeability selectivity developed based on experimental data. The optimum achieving highest performance obtained at 4.76 bar, 30 °C 90 vol%, which resulted 687.20 Barrer, 71.03 Barrer 8.92. deviation corresponding data was found to be an acceptable range, confirming suitability RSM predicting consequently optimizing variables.
