Outline of Final Research Achievements

We have newly developed and clarified the atmospheric-pressure low-temperature nonequilibrium plasma combined exhaust gas cleaning process, which is the basis of the development of clean marine diesel engine systems. Since heavy oil containing sulfur is used as fuel in marine diesel, SOx in exhaust gas causes catalyst deterioration, and it is difficult to use the catalyst for exhaust gas cleaning except for a few materials. In this study, the carbon dioxide, NOx, and PM reduction characteristics of the plasma combined process, which is highly insensitive to SOx, was clarified by experiments and numerical simulations.

Academic Significance and Societal Importance of the Research Achievements

化石燃料燃焼装置からの排ガス浄化のために,白金,金,銀,パラジウムなどの貴金属やレアメタルが広く用いられているが,価格高騰など早晩の不足が予想されている。また,本研究が対象とする船舶ディーゼルにおいては,燃料に硫黄を含む重油が使用されるため,排ガス中SOxによる触媒劣化が生じ,排ガス浄化に触媒を使用することが困難である。本研究では大気圧プラズマ複合排ガス処理プロセスを船舶ディーゼルエンジンに適用した。プラズマは高電圧高速立ち上がり超短幅ナノ秒パルス放電等により形成され,省エネルギーに形成できる。プラズマを排ガス中で発生させPM2.5フリーマリンディーゼルエンジンを試行した新規な研究である。
