Abstract

In this work, a fixed bed reactor is evaluated for CO2 capture from ambient air using an amine based ion exchange resin. Using adsorption experiments, the effect of superficial velocity and bed length on process economics is investigated. It is shown that the optimal conditions are found at an adsorption duration of 0.5-1.5 times the stoichiometric time for sorbent loading. To reduce pressure drop during adsorption, a radial flow reactor is proposed and designed for capturing CO2 from ambient air.
