    • A process for operating a palladium oxide-containing catalytic combustor is useful, e.g., for powering a gas turbine. The palladium oxide is supported on a metal oxide such as alumina, lanthanide metal oxide-modified alumina, ceria, titania or tantalum oxide. The method involves maintaining control of the temperature within the combustor in such a manner as to insure the presence of palladium oxide. By maintaining the temperature below the decomposition onset temperature of palladium oxide (which is catalytically active for catalytic combustion) into metallic palladium (which is catalytically inactive) deactivation of the catalyst is avoided and high catalytic activity is retained. Regeneration of catalyst following inactivation resulting from an over-temperature is accomplished by using a heat soak in a regeneration temperature range which varies depending on the particular metal oxide used to support the palladium oxide.
    • 用于操作含氧化钯的催化燃烧器的方法是有用的，例如用于为燃气轮机供电。 氧化钯负载在氧化铝，镧系金属氧化物改性氧化铝，二氧化铈，二氧化钛或氧化钽等金属氧化物上。 该方法包括以确保氧化钯存在的方式维持燃烧室内温度的控制。 通过将低于催化燃烧的氧化钯（其对于催化燃烧具有催化活性）的分解开始温度维持在金属钯（其是催化无活性的）中，避免了催化剂的失活，并且保持了高催化活性。 通过使用根据用于支撑氧化钯的特定金属氧化物而变化的再生温度范围内的热浸泡来实现由过温引起的失活后催化剂的再生。

    • The subject of the invention relates to a catalytic pyrolysis device primarily for the neutralisation of dangerous combustion products and waste materials, the elimination of flue gases and the utilisation of complex carbon chains, which contains a housing body enclosing a reaction space and an active material coating covering at least part of the inner side of the housing body, where the housing body is a ceramic material with a solid core and a porous shell that has depressions suitable to receive the particles of the active material coating at least on the boundary surface of the core facing the reaction space, the active material coating has a nickel base containing magnesium. The characteristic feature of the device is that the core (21) of the housing body (20) is from a protoenstatite ceramic stabilised with a sintered glassy phase, and the porous shell (22) at least partially covering the core (21) is from 0.6-1.1 mm thick magnesium silicate with added alpha-corundum, and the active material coating (23) located on the porous external surface (22a) of the shell (22) is Ni-Mg oxide produced using heat treatment from a Ni-Mg double salt and, in a given case, contains Ni-Si components. The subject of the invention also relates to the production of the housing body structure of a catalytic pyrolysis device primarily suitable for to the neutralisation of dangerous combustion products and waste materials, the destruction of flue gases and the utilisation of complex carbon chains, during which we form a core material, the formed core material is subject to heat treatment, following this it is coated with a shell former, then is again subjected to heat treatment, following this the shell is given an active material coating, and finally is subjected to a further heat treatment. The characteristic feature of the invention is that for the raw material for the production of the solid core (21) we use 50-65 mass% finely ground talcum powder, 15- 35 mass% talcum powder fired at 1200+50°C and/or talcum powder, 4-7 mass% magnesium carbonate and 5-9 mass% barium carbonate, and, in a given case, 0.1-0.2 mass% rutile titanium dioxide, then the raw material is shaped by pressing and is fired at 750±10 °C, then as a porous shell (22) by immersion and/or spraying we apply a fine ground material slurry to the boundary surface (21a) of the solid core (21) produced in this way consisting of 6-14 mass% fine grain calcinated alpha corundum, 4-9 mass% white burning plastic fine clay, 55-68 mass% raw talcum and 22-28 mass% talcum powder fired at 1200+50 and 3-12 mass% paper industry grade pulped cellulose fibre, 0.1-0.2 mass% ammonium lignosulphate and 0.2-0.8 mass% tri-methylcellulose with a molar mass of between 1000-5000, we apply a material mixture with a density of 1250-1300 g/l and we continue thickening the porous shell (22) until the theoretical post-firing thickness of the porous shell (22) reaches 0.6-1.1 mm, following creating the porous shell (22) the housing body (20) is dried and fired at 1200±10 °C, then the housing body (20) with its solid core (21) and porous shell (22) is dipped once or several times in a Ni-Mg double salt melt and then any surplus is removed from the housing body (20) an in this way an active material coating is applied to the housing body (20), then finally the housing body (20) with the applied active material coating (23) is heat- treated at 600±10 °C.
