Experimental Results of a Combined DBD Reactor-Catalyst Assembly for a Direct Marine Diesel-Engine Exhaust Treatment

This paper gives an overview of a robust dielectric barrier discharge reactor-catalyst construction used in a bypass of a marine diesel-engine exhaust gas system. Electrode arrangement, housing, and electrode positioning systems are discussed allowing for high temperature and reasonable vibration operation. Preliminary test results are given considering the chemical reactions, particulate matter, and CO and HC reductions. An operative removal efficiency up to 99 percent is obtained (relative percentage units with respect to initial maximal concentrations). The basics of power supply construction and output waveforms are given.
