摘要： A catalyst composition for facilitating the oxidation of soot from diesel engine exhaust is provided. The catalyst composition includes a catalytic metal selected from Pt, Pd, Pt—Pd, Ag, or combinations thereof, an active metal oxide component containing Cu and La, and a support selected from alumina, silica, zirconia, or combinations thereof. The platinum group metal loading of the composition is less than about 20 g/ft3. The catalyst composition may be provided on a diesel particulate filter by impregnating the filter with an alumina, silica or zirconia sol solution modified with glycerol and/or saccharose, impregnating the filter with a stabilizing solution, and impregnating the filter with a solution containing the active metal oxide precursor(s) and the catalytic metal precursor(s). The resulting catalyst coated diesel particulate filter provides effective soot oxidation, exhibits good thermal stability, has a high BET surface area, and exhibits minimal backpressure.

摘要： The present invention provides a regenerable catalyst composition suitable for entrapping SOx. The composition of the invention comprises a copper oxide having the formula (Cu/(A oxide) where A oxide is SiO2, Zr—SiO2, Al2O3, TiO2—Al2O3, ZrO2 and In2O3 or mixtures thereof. Copper loading may vary from about 10 to 60 mol % and is preferably about 25 mol %. The catalyst composition adsorbs SOx as metal sulfate under lean conditions and desorbs accumulated SOx as SO2 under rich conditions. Such reversible SOx trap are able to operate under conventional NOx trap operating conditions to prevent sulfur poisoning of the NOx trap. Furthermore, these traps may be regenerated under rich conditions at 300-450° C. In another embodiment of the present invention, an irreversible SOx trap capable of collecting SOx under lean conditions is provided. The traps of this embodiment include praseodymia, zirconia-praseodymia and mixed manganese-yttria and mixtures thereof.

摘要： A catalyst composition is provided for use on a diesel particulate filter which facilitates the oxidation of soot from diesel engine exhaust and which generates low NO2 emissions during regeneration of the filter. The catalyst composition includes a catalytic metal comprising a platinum group metal selected from Pt, Pd, Pt—Pd, or combinations thereof, an active metal oxide component containing Cu and La; and an oxide component selected from oxides of Co, Fe, or combinations thereof. The catalyst composition includes a support selected from alumina, silica, zirconia, or combinations thereof. The catalyst composition may be provided on a diesel particulate filter by impregnating the filter with an alumina, silica or zirconia sol solution modified with glycerol and/or saccharose, impregnating the filter with a stabilizing solution, and impregnating the filter with a solution containing the catalyst metal precursor(s), the active metal oxide precursor(s) and the Co or Fe oxide(s). The resulting catalyst coated diesel particulate filter provides effective soot oxidation, exhibits good thermal stability, has a high BET surface area, exhibits minimal backpressure, and produces low NO2 emissions during filter regeneration.
