Sequestration of CO2 using emulsion phase structure

Abstract

This study proposes a cost-effective method for creating an emulsion structure to capture 100 % of the CO2 released during chemical reactions. The emulsion, composed of water, kerosene, sodium lauryl sulfate (SLS), sodium hydroxide (NaOH), triethylamine (TEA), and amine-functional ion exchange resin (IER), demonstrates high CO2 capture efficiency. Results indicate that a 10 mL emulsion sample could capture 12.72 g of CO2, representing 95.4 % of the total CO2 produced during the chemical reaction between acetic acid and sodium carbonate. In contrast, an ion exchange resin granule captures only 0.01 g of CO2. Consequently, 10 mL of emulsion sample containing 60 units of IER is necessary to achieve 100 % CO2 capture.
