Abstract

HNCO is an important composition in chemical reaction processes in marine Urea-SCR systems. This paper reported on HNCO hydrolysis and reduction in marine Urea-SCR systems. Firstly, by using different catalysts, this paper carried out the experimental study on the catalytic hydrolysis process of HNCO, the effects of different catalysts on HNCO hydrolysis and the actions of varied parameters together with NH3 on HNCO hydrolysis. As results, the optimal operation conditions of HNCO hydrolysis were obtained. Secondly, by using HNCO as a reductant, the paper carried out the HNCO reduction experiments to analyze the denitration rate under varied test parameters. While by comparing the effects on reduction process of NH3 reductant, the regulations of HNCO reduction reactions were drawn. The results are of important reference value for the further research of ship Urea-SCR technology and are helpful in further optimizing Urea-SCR systems.
