Abstract

Catalytic reduction of N20 exhaust diesel emissions by NaOH spray system A. Sudrajad, N. Osami, F. Hirotsugu & H. Wataru Energy Engineering Laboratory, Kobe University of Mercantile Marine, Japan Abstract The removal of acid-gases such as sulfur dioxide (SOz) is important for controlling the nitrous oxides (N20) exhaust emission of diesel engines. An experimental study on the interaction between nitrous oxides emissions in the presence of SO2 is proposed. Here we report a study of a new attempt to use the NaOH catalyst by spray system for small diesel engines as short of post exhaust gas treatment. The result has shown that with increasing temperature, or increasing oxygen concentration, the emissions of N20 increase; also with an increase in the level of SO2 the N20 emissions increase. The experiment using NaOH spray system cooled the temperature of exhaust gases and absorbed the acid-gas (sulfur dioxide), with the result that N20 decreased. This system aims to reduce the N20 emitted for land
