Abstract
This study investigates the performance of the Pebax membrane in CO 2 adsorption and permeation processes. The adsorption tests were conducted using a gas adsorption reactor based on the solubility approach, with adsorption capacity determined from system pressure variations. SEM characterization revealed a smooth and homogeneous surface with the presence of microvoids that contribute to an enhanced CO 2 adsorption capacity of up to 397.53 mg/g. The linear relationship between adsorption capacity and pressure variation was used to determine the solubility coefficient, while the slope of the qt versus t 1/2 plot provided the diffusion constant. Based on the obtained solubility and diffusion values, the calculated CO 2 permeability of the Pebax membrane indicates strong gas transport properties, confirming its potential as one of the most promising adsorbent materials for smart decarbonization and sustainable carbon capture applications.
