Membrane technology for carbon capture has been favored to mitigate climate change attributed to the greenhouse effect in recent years. The implementation of composite membranes with a selective layer made from CO 2 -selective polymers and nanofillers is gaining particular interest for efficient CO 2 capture, with the benefits of easy processability, costeffectiveness, and excellent separation performance. Graphene oxide (GO) with abundant oxygen-containing functional groups exhibits tremendous potential for enhancing mechanical and transport properties when incorporated into the polymeric matrix. Herein, a GO-reinforced polyacrylamide/poly(vinyl alcohol)/polysulfone (PAM/PVA/PSf) composite membrane was developed with a focus on improving the CO 2 /N 2 separation performance. The membrane performance was tested with mixed gas (10/90 vol % CO 2 /N 2 ) under humidified conditions. The effects of the preparation parameters (e.g., GO content and pH of the casting solution) and the operating parameters (e.g., feed flow rate, feed pressure, temperature, and relative humidity) were systematically investigated and further optimized to identify the optimal condition for post-combustion carbon capture. The best membrane performance with a CO 2 /N 2 selectivity of 65 and a CO 2 permeance of 55 gas permeance units (GPU) at 2 bar and 30 °C was documented in this study. The development of CO 2 -selective composite membranes may address the challenges associated with the upscaling of membrane technology for potential industrial carbon capture.

Heterogeneous membranes, otherwise known as Mixed Matrix Membranes (MMMs), which are used in gas separation processes, are the subject of growing interest. This is due to their potential to improve the process properties of membranes compared to those of homogeneous membranes, i.e., those made of polymer only. Using such membranes in a process involves subjecting them to varying temperatures and pressures. This paper investigates the effects of temperature and feed pressure on the process properties of homogeneous and heterogeneous membranes. Membranes made of Pebax®2533 copolymer and containing additional fillers such as SiO2, ZIF−8, and POSS-Ph were investigated. Tests were performed over a temperature range of 25–55°C and a pressure range of 2–8 bar for N2, CH4, and CO2 gases. It was found that temperature positively influences the increase in permeability, while pressure influences permeability depending on the gas used, which is related to the effect of pressure on the solubility of the gas in the membrane.
