In order to reduce ship CO_2 emissions, this paper comes up with the idea of recovering CO_2 from ship exhaust by Na OH solution and improves the absorption rate by adding Ca O solid particles. The effect mechanism of Ca O solid particles on CO_2 absorption efficiency is analyzed in detail, and the mathematical model is deduced and the Ca O enhancement factor is calculated through experiments. Experiment result demonstrates that the effect of CaO solid particles on the absorption of CO_2 in alkali solution is significant. The absorption rate of pure CO_2 gas,the simulated ship exhaust gas and 6135 AZG marine diesel engine emission can be increased by 10%, 15.85% and10.30%, respectively.
