摘要： There is disclosed a process for producing metallic fiber boards with functionalization of the surface by catalysts. The resulting boards are employed particularly in the catalytic combustion of hydrocarbons, especially in the methane combustion of household boilers, to reduce NOx formation by lowering the temperature of combustion. The process consists of thermal oxidation of metallic fibers, deposition of a porous oxide layer by atomisation of a precursor solution on first oxide layer and calcination, and functionalization of second layer. The fiber mat comprises preferably fibers of an alloy containing iron, chromium and aluminium (Fecralloy®), the catalytically active component comprises preferably a group VIII noble metal (palladium or rhodium).

摘要： A process for preparing calcium oxide, strontium oxide or barium oxide consists in the treatment of the corresponding hydroxides following the reactions (I): Ca(OH)2 → CaO + H2O; (II): Sr(OH)2 → SrO + H2O; (III): Ba(OH)2 → BaO + H2O; at temperatures comprised between 400 and 900 °C during a time between 1 and 15 hours under vacuum or in an inert gas atmosphere. Preferably said reaction is caused to take place in a capsule with at least a portion of surface being permeable to the gas flow.

摘要： A method is disclosed for the manufacture of a supported thin layer of getter material, comprising: preparing at least one suspension of NEG material particles, with a particle size lower than about 150 νm, in a dispersing medium having an aqueous, alcoholic or hydroalcoholic base, containing a weight percentage of organic compounds, having a boiling temperature higher than 250 °C, which is lower than 1 %, wherein the ratio of the NEG material weight to the weight of dispersing medium is comprised between 4:1 and 1:1; depositing at least one layer of NEG material suspension onto a metal carrier by serigraphic technique; drying the thus obtained deposit by allowing the volatile components to evaporate; and sintering in a vacuum oven the dried deposit at a temperature comprised between 800 and 1000 °C and operating under vacuum, covering the deposit by means of a material not suffering from physical or chemical alterations under vacuum at any process temperature. It is also disclosed a getter device obtained according to such a method.
