1. Introduction
In response to strengthened International Maritime Organization (IMO)
regulations, the “Super-clean Marine Diesel” research and development project
was initiated and overseen by Japan Marine Equipment Association and promoted
by the Nippon Foundation, led by the Ministry of Land, Infrastructure,
Transportation and Tourism. Mitsubishi Heavy Industries, Ltd. (MHI) and Akasaka
Diesels Ltd. are participants in this project, which aims to develop selective
catalytic reduction (SCR) for slow-speed diesel engines. We will complete a
verification test for the first step of this project using a land test rig this
September. This article provides an outline of our activities to date.

Reduction Using Dielectric Barrier Discharge and NH3 Selective Catalytic
Reduction in Diesel Exhaust

Abstract
A combined De-NOx technique of a non-thermal plasma and a selective catalytic
reduction (SCR) using NH3 has been investigated to remove NOx from a 300
hpmarine diesel engine exhaust under low temperature conditions (100–200 oC).
As results, De-NOxefficiencies for the combined process were increased from 20
to 80 % at 100 oC compared to a SCR sole process. Since a non-thermal plasma
could convert NO into NO2, a fast SCR reaction by which a equal amount of NO
and NO2 reduced to nitrogen could be activated in a relatively low temperature
range. Furthermore from the measurement of smoke-meter, over 45 % of PM was
reduced and the size distribution of PM was significantly altered after plasma
process. This feature will be helpful to continuously regenerative DPF systems.
