Membrane technology has attracted great attention by the researhcers especially in gas separation process due to their simple process design and low capital cost as compared to the conventional techniques. Interestingly, in this work, oil palm frond (OPF) waste was used as nanoadsorbent embodied in polyether block amide (Pebax 1657) nanocomposite membrane to improve the CO2/CH4 separation. The effectiveness of the nanoadsorbent derived from OPF was evaluated by varying the nanoadsorbent concentration (2–8 wt%) and controlling the Pebax 1657 concentration (5 wt%), dipping time (5 s) number of sequential coatings (3 layers). The pore characteristics of the nanoadsorbent was analysed using Brunauer–Emmett–Teller (BET) analysis. The morphology and the existence of active groups in the newly synthesized nanoadsorbent and nanocomposite membranes were investigated by field emission scanning electron microscopy (FESEM) and fourier transform infrared spectroscopy (FTIR), respectively. The single gas permeation process was carried out at constant pressure (2 bar) and at room temperature (25± 5 °C). The optimum condition with 5 wt% nanoadsorbent made the nanocomposite membrane exceed the trade–off limit of Robeson plot with a CO2 permeability and CO2/CH4 selectivity of 1475.09 Barrer and 40.48, respectively.
