MEA―TiO2 (MT) CO2 sorbent is synthesized using pure MEA and a support material, TiO2. The performance of the MT sorbent on CO2 separation was investigated in tubular reactors under various experimental conditions. The sorption capacity of the MT sorbent reached 1.09 mol-CO2/kg-MT at 45 wt % MEA. However, an optimum of 40 wt % MEA loading was chosen for most of the sorption tests. Temperature affected the CO2 sorption capacity considerably, with optimum values of 45 °C for adsorption and 90 °C for regeneration, while humidity had a small positive effect. TiO(OH)2 appears to be the best support material for MEA, but more evaluation is needed. The MT sorbent is regenerable, with a multicyde sorption capacity of ∼0.91 mol-CO2/kg-MT under the given experimental conditions.
