A REVIEW ON SOLID SELECTIVE CATALYTIC REDUCTION FOR POST COMBUSTION NOx
REDUCTION IN CI ENGINES
Abstract
Increasing rate of pollution is a matter of global concern nowadays. One
of the major sources of pollution is found to be the combustion products
of diesel engine containing hazardous gases like carbon mono oxide,
carbon di oxide, unburnt hydrocarbons and oxides of nitrogen. NOx
reduction from exhaust of diesel engines is the topic of research for
automobile Manufacturers nowdays. Lean NOx trap was used for a long time
for this purpose but it was not successful. Then SCR technology came
into existence which was found to be the very effective Technology for
reduction of nitrogen oxides from diesel engine exhaust. This paper
involves the study of a better NOx reduction technology called solid
selective catalyst reduction (SSCR). After analysis the results of
various experiments it is concluded that NOx reduction efficiency of
about 95% can be easily achieved using SSCR system.
