  • Publication number: 20090232714
    Abstract: A particulate combustion catalyst which includes a carrier containing a cerium-zirconium double oxide having a cerium oxide content of 5 to 50 mass %, or a carrier containing a cerium-zirconium-based double oxide containing an oxide of at least one metal selected from Nd, La, Fe, Y, Pr, Ba, Ca, Mg, Sn, and Sr in an amount of 1 to 35 mass %, and having a cerium oxide content of 5 to 50 mass %; and at least one metal selected from Ag, Ru, and K, or an oxide thereof supported on the carrier, and at least one metal selected from among Pt, Pd, and Rh supported on the carrier in an amount of 0.01 to 2 mass %. A particulate filter and an exhaust gas cleanup system having the catalyst are also disclosed. Employment of the particulate combustion catalyst realizes removal of soot through oxidation at low temperature without employment of an expensive noble metal.

  • Patent number: 6831036
    Abstract: A co-catalyst for purifying an exhaust gas which can be used for a loner period of time as an actual catalyst by using the cerium oxide in the conventional co-catalyst for purifying the exhaust gas as a cerium-containing complex oxide for elevating the resistance to heat and suppressing the performance reduction due to thermal deterioration and by making a specific surface area and an oxygen storage capacity over specified values. A co-catalyst for purifying an exhaust gas of the present invention includes a composite oxide including (a) cerium; and (b) at least one element selected from the group consisting of zirconium, yttrium, strontium, barium and a rare-earth element supported on a particulate aluminum oxide support; a specific surface area of the co-catalyst after sintering being not less than 40 m2/g; an oxygen storage capacity at 400° C. being not less than 10 &mgr;mols/g and an oxygen storage capacity at 700° C. being not less than 100 &mgr;mols/g.

  • Patent number: 6403875
    Abstract: A process for producing a thermoelectric material comprising mixing at least two of bismuth, tellurium, selenium, and antimony and, if desired, a dopant, melting the mixture, grinding the resulting alloy ingot, forming the powder, and sintering the green body under normal pressure, or hot pressing the powder, wherein the grinding and the normal sintering or hot pressing are carried out in the presence of a solvent represented by CnH2n+1OH or CnH2n+2CO (wherein n is 1, 2 or 3).
