Outline of Final Research Achievements

The studies on SOx solid adsorbent and CO2 separation have been conducted to reduce SOx, NOx and GHG emissions from marine diesel engines. Several procedures were investigated to produce solid desulfurizing agents with higher porous microstructures that enable high reactivity of the absorbent. The desulfurization ability was evaluated by using exhaust gas from a 4-stroke middle speed engine operating with heavy fuel oil. 200 gram adsorbent could keep the high SO2 reduction rate of about 60% even after one and half hour later from the start of the experiment. We also conducted a basic experiment to investigate the effect of inlet gas composition on exhaust gas emission and designed an exhaust gas recirculation system with a CO2 separation filter.
