Influence of doping MnCl 2 in Ce,Fe and Al lattice on its oxygen storage capacity to use as a synthesis catalyst for reducing emission in IC engine

Abstract

A series of MnCl₂ catalysts were synthesised in order to study the Ce/Al/Fe ratios and Ce/Al/Fe catalyst as an external effect of morphological support to reduce NO (nitrogen oxide) emission with NH₃ while working at low temperatures. When compared to other low-temperature catalysts, the NOx conversion result is also high. The Ce/Al/Fe ratio was 1:1:1 above the MnCl₂ catalyst, indicating that the surface acidity is high and that the NH₃ side reaction was inhibited. Mould catalysts are commonly used in selective catalytic reduction (SCR) reactions because they contain Ce/Al species and have a high oxygen content. The hydrothermal method utilised to make the catalyst in a mould pattern improved the NOx conversion efficiency. During the Quick SCR reaction technique, MnCl₂ oxygen levels increased while NO emissions decreased. The NO emission is reduced by almost 26.28% and the other emissions, such as HC and smoke, are reduced by around 4.34% and 15.62%, respectively, compared to HTSO100 and compare to diesel, NO emission reduced around 34.5% whereas other emission like HC and smoke reduced around 8.33% and 16.92%, respectively, which is due to the addition of an MnCl_2 +CeCl₂ +FeCl₂+ AlCl₂ in the exhaust without affecting brake thermal efficiency.
