T. Inui et al., DECOMPOSITION OF NITRIC-OXIDE ON METALLOSILICATES UNDER A LARGE EXCESS OXYGEN CONDITION WITH COEXISTENCE OF A LOW CONCENTRATION CETANE, Catalysis letters, 13(1-2), 1992, pp. 87-94
Catalytic removal of NO was conducted under the condition of large exc
ess O2 by using different kinds of metallosilicates having MFI structu
re. With coexistence of a low concentration of cetane, H-Fe-silicate,
which had both acidity and redox property, exhibited the maximum perfo
rmance among the catalysts tested at a fairly lower temperature range,
around 350-degrees-C, and the NO was totally converted. The temperatu
re dependence of NO conversion was consistently similar to that of cet
ane combustion.
