Paper Title
A Review Study of Selective Catalytic Reduction
  Swagat S. Giri,  Himant Hedaoo,  Mrudang Wagh

Nowadays exhaust emission control from internal combustion engines have become one of the most important challenges.. Oxides of nitrogen (NOx) are one of the major hazards pollutants that come out from the engines. Control of emission in internal combustion engines can be achieved either by controlling combustion or by treating the exhaust gas. The latter is comparatively easier since there is less or no need to modify the engine itself. One such treatment method is the use of catalytic converters. The use of selective catalytic reduction, reduction of a particular emission based on the type of the engine used. In the selective catalytic reduction (SCR) process, NOx reacts with ammonia, which is injected into the flue gas stream before the catalyst. Different SCR catalysts such as vanadium oxide or metal substituted zeolites have different operating temperature windows and must be carefully selected for a particular SCR process. Ammonia-SCR has been used in industrial processes, in stationary diesel engines, as well as in some marine engines. This Study aims to how to reduce of NOx in CI engines using Selective Catalytic Reduction and its optimization. Various catalysts used in SCR system are studied and also pre-oxidation of the exhaust gases to increase the rate of reaction at the SCR catalyst along with their effects on the performance and emission characteristics of the engine is also discussed.

Keywords- Engine Emission, Catalyst, SCR
