Temperature Swing Adsorption Process for CO2 Capture Using Polyaniline Solid Sorbent

On the potential of phase-change adsorbents for CO2 capture by temperature swing adsorption.

We investigate the potential of a class of recently discovered metal-organic-framework materials for their use in temperature swing adsorption (TSA) processes for CO2 capture; the particularity of the considered materials is their reversible and temperature dependent step-shaped CO2 adsorption isotherm. Specifically, we present a comprehensive modeling study, where the performance of five diffe...

Development of a Pressure Swing Adsorption (PSA) Process for CO2 Capture from Flue Gas

Advanced Modeling and Control of a Solid Sorbent-Based CO2 Capture Process

Solid sorbent-based CO2 capture from flue gas provides a novel alternative to traditional solvent-based processes due to potentially lower energy consumption for regeneration. Optimal operation of such a gas-solid flow process requires an advanced control framework for efficient disturbance rejection and setpoint tracking. This work focuses on the development of computationally fast and accurat...

Investigation of carbon dioxide capture from hydrogen using the thermal pressure swing adsorption process: Central composite design modeling

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...

Capture of Co 2 by Vacuum Swing Adsorption Process Using Activated Carbon Beads

Pitch-based AC beads (particle size about 1mm) were synthesized from coal tar pitch through the emulsion method without using binder material in our laboratory. Adsorption equilibrium and adsorption kinetics of CO2 and N2 on the activated carbon beads were studied experimentally and theoretically. Based on the equilibrium and kinetics data, an improved vacuum-pressure swing adsorption (VPSA) pr...
