A STUDY EVALUATE PERFORMANCE OF (CuO)0.3-(MnO2)0.7/Al2O3-CeO2-ZrO2/FeCrAl THREE WAY CATALYST APPLIED IN AUTOMOBILE ENGINE

Abstract

This paper study performance of (CuO)0.3-(MnO2)0.7/Al2O3-CeO2-ZrO2/FeCrAl
Three Way Catalytic (TWC) using on Toyota Vios 1.5 engine, TWC is prodcucted by
spin coating method, TWC of dimension was 100x250 respectively, the intensity
of cell was 400 cell/inch2, amount of Al2O2, CeO2 and ZrO2 washcoat materials are
163, 18 and 52 respectively, (CuO)0.3-(MnO2)0.7 materials of 21.5gram were used.
The structure of TWC is chacacteristic by XRD và SEM, catalytic performance was
carried on APA100 and CEB II (AVL) bench using Toyota Vios 1.5 engine. The results
showed that, the XRD peaks of Al2O3, CeO2, ZrO2 were determineded, the peak of
CuO, MnO2 and Spinel CuxMnyOz compound were also showed by the XRD. The
experiment results on Toyota Vios 1.5 engine showed that, the highest
performance of CO, HC and NOx was 54.7%, 38.1% và 70.7%, when throttle and
speed increased, CO, HC and NOx conversion perfomance trendly decreased. At
<1, the CO and HC performance decreased strongly.
