Abstract

In the present study, a new carbon capture device that can be carried on-board vehicles has been developed and tested. The developed device has employed absorption and adsorption methods of post-combustion CO2 capture. Sodium hydroxide (NaOH) pellets and calcium hydroxide Ca(OH)2 have been used as solvents and sorbents in the device. The CO2 capture efficiency has been evaluated at a wide range of operating conditions. The results showed that the higher the concentration of the solvent, the higher the capture efficiency with 100% capture efficiency has been obtained at full saturation of NaOH. In addition, the increase in the solution temperature increases the capture efficiency up to 50°C. Design of the gas distributor in the device has also a notable effect on CO2 capture. It was found that solvent prepared with seawater can provide high capture efficiency over a wide range of operation, but in general, it has a lower capture efficiency than that prepared by tap water. Moreover, solvents prepared by NaOH has a superior CO2 capture efficiency over those prepared by Ca(OH)2. For the adsorption technique, a 50% NaOH and 50% Ca(OH) mixture by mass has provided the highest capture efficiency compared with each sorbent when used alone.
