This study proposes a simple and energy efficient technique for methane (CH4) capture from low concentration emission sources. An extrusion-based process was used to fabricate magnetic framework composites (MFCs) from a metal organic framework (MOF), aluminum fumarate, and MgFe2O4 magnetic nanoparticles (MNP). Methane uptake for MFCs with different MNP loading at 1 bar and 300 K revealed a high methane uptake of up to 18.2 cm3 g-1. To regenerate the MFCs, a magnetic induction swing adsorption (MISA) process was applied. A working capacity of 100% was achieved for the MFC over 10 adsorption-desorption cycles with an average of 6 min per cycle for the regeneration step. The ability to access 100% of the adsorbed CH4 in the MFC with rapid and localized heating achieved with the MISA process potentially provides an energy efficient technique for CH4 capture and reuse from low concentration sources.
