T
he SCR technology for the control of NOx emission from Marine Diesel engine was brought to the IMO Tier 3 regulation
for marine diesel engine applications. SCR system is effective over a wide temperature region to reduce NOx emission
from engine exhaust emission during rich and lean operations. In this paper, SCR catalyst of V

SCR catalysts. The kinetic analysis was carried out using a commercial one-dimensional
aftertreatment code, coupled with an optimizer. In this paper, the development of a steady kinetic model of the Urea-SCR
process for vanadium-based catalysts is presented. The model was based on the results from reactivity, chemistry, catalytic
mechanism, and kinetics of NH
