  • Patent number: 7737081
    Abstract: This invention relates to a method of operating a catalyst for treating the exhaust gas of an internal combustion engine, the catalyst comprising, in addition to catalytically active noble metals, also storage components for storing hydrocarbons. During engine operating phases at low exhaust-gas temperatures, such a catalyst stores the hydrocarbons contained in the exhaust gas without burning them. When the exhaust-gas temperature rises, these hydrocarbons are desorbed again and then oxidized at the catalytically active noble metals. This process can lead to uncontrolled, vigorous combustion of the hydrocarbons stored on the catalyst and, therefore, damage to the catalyst. According to the invention, this damage is avoided by continuously calculating the respective loading of the storage components with hydrocarbons and repeatedly regenerating the storage components depending on the loading by temporarily raising the exhaust-gas temperature before damage to the catalyst can occur.

The additional oxide forms SO3 or SO4 from SO2 in an oxidizing atmosphere, and stores sulfur components as a sulfide in a reducing atmosphere so that emission of H2S can be restrained.

  • Patent number: 7713910
    Abstract: The present invention provides a method for manufacture of supported noble metal based alloy catalysts with a high degree of alloying and a small crystallite size. The method is based on the use of polyol solvents as reaction medium and comprises of a two-step reduction process in the presence of a support material. In the first step, the first metal (M1=transition metal; e.g. Co, Cr, Ru) is activated by increasing the reaction temperature to 80 to 160° C. In the second step, the second metal (M2=noble metal; e.g. Pt, Pd, Au and mixtures thereof) is added and the slurry is heated to the boiling point of the polyol solvent in a range of 160 to 300° C. Due to this two-step method, an uniform reduction occurs, resulting in noble metal based catalysts with a high degree of alloying and a small crystallite size of less than 3 nm. Due to the high degree of alloying, the lattice constants are lowered.

  • Patent number: 7709541
    Abstract: An improved skeletal iron catalyst is provided for use in Fischer-Tropsch synthesis reactions for converting CO and H2 to hydrocarbon products. The skeletal iron catalyst is manufactured using iron and a removable non-ferrous component such as aluminum. The iron and removable non-ferrous component are mixed together to form a precursor catalyst and then a portion of the removable non-ferrous component is removed to leave a skeletal iron catalyst. One or more first promoter metals and optionally one or more second promoter metals are incorporated into the skeletal iron catalyst either by blending the promoter into the precursor catalyst during the formation thereof or by depositing the promoter on the skeletal iron. The first promoter metals comprises a metal selected from the group consisting of titanium, zirconium, vanadium, cobalt, molybdenum, tungsten, and platinum-group metals.
