Development of after treatment system on CO{sub}x with seawater electrolysis for marine diesel engine

摘要

On the GHGs (Green-House Gases) exhausted from marine diesel engine, there are on overwhelming majority on marine CO{sub}2 (11,6134ton-Carbon). However, the drastic system to reduce CO{sub}2 has not been fundamentally settled ever today. This research makes a new technology to use the electrolyzed seawater for an after-treatment of marine CO{sub}2. This method produces a large amounts of an alkaline solution (pH = 10) in the cathode room of electrolytic bath (5A,10V), and there are the soluble reaction by the bubbled CO{sub}2 gas. The maximum removal rate of CO{sub}2 is about 80% from the experimental results.
