Control of Nitrogen Oxides in Diesel Engine Exhaust by Catalytic Reduction
نویسندگان
چکیده
The nitrogen oxides (NOx) are prominent and harmful pollutants in the exhaust of diesel engines. The reduction of NOx to harmless products using catalysts is proved to be a remedy. The present study attempts to reduce NOx emissions in the exhaust of low heat rejection (LHR) diesel engine by catalytic reduction, using lanthanum ion exchanged zeolite (catalyst-A) and urea infused lanthanum ion exchanged zeolite (catalyst-B) under varied conditions . The effect of temperature of catalyst, space velocity, and void ratio on the reduction of NOx in the exhaust of the engines are also studied and compared with the conventional engine (CE) under identical conditions. The study showed a considerable reduction by 40-50% in NOx emissions.

When looking at the effects of diesel engine exhaust on the environment, it is important to first look at the composition of the exhaust gases. Over 99.5% of the exhaust gases are a combination of nitrogen, oxygen, carbon dioxide, and water. With the exception of carbon dioxide, which contributes about 5% of the total volume, the diesel engine exhaust consists of elements which are part of...
