Development of volumetric adsorption system for multicomponent gas capture: Utilizing bio-metal organic framework for CO

A novel three-chamber volumetric multicomponent gas system is developed to monitor CO₂ adsorption for carbon capture systems. Using ultrasonic-synthesized Bio-MOF Co-Glu adsorbent, a water bath and coil heaters has been maintained isothermal conditions for CO₂ adsorption in an 85:15 CO₂/N2 at 27°C and pressures of 12 bars. Both measuring cells (Main Chamber-1 and Main Chamber-2) showed a maximum CO₂ adsorption capacity of 0.12 g/g. X-ray diffraction, Fourier-transform infrared spectroscopy, and Brunauer-Emmett-Teller confirmed, biological metal organic framework doped Cobalt Glu gas capture capabilities with its crystalline structure, functional groups, and wide surface area. Advanced volumetric methods for multicomponent gas adsorption estimate partial pressures and individual gas uptakes in mixtures based on a volumetric framework, with non-ideal gas behaviour, The results show that the biological metal organic framework doped Cobalt Glu adsorbent coupled with volumetric equipment may advance multicomponent gas adsorption research.
