  • Grid of precious metals for the recovery of platinum metals escaping from a catalyst during the reaction, and especially of platinum during oxidation of ammonia
    Patent number: 4239833
    Abstract: The subject of the invention is a grid of precious metals for the recovery of platinum metals escaping from a catalyst during the reaction of oxidation of ammonia in the production process of nitric oxide.In the reactions conducted in the presence of the catalysts containing platinum metals at the incandesence temperature a loss in the mass of precious metals occurs, which disadvantageously effects the economy of the process.For the recovery of platinum escaping from a catalyst during the reaction of oxidation of ammonia the grids mainly used are those made of palladium-gold alloy, which, in order to increase their strength, are spot-welded into packs, or the separating grids of heat-resisting materials are used.The known methods of increasing the strength and the durability of the recovery grids are disadvantageous, as the flow of reactants through a pack of grids meets additional resistance, which causes a decrease of the process effectiveness.

  • Gas-lubricated bearing
    Patent number: 3960414
    Abstract: A gas-lubricated bearing is provided with a bushing mounted in a housing by means of elastic rings mounted on ends. The surface of the hole in which the bushing is mounted, the outer surface of the bushing and the side surfaces of elastic rings form a chamber, in which throttling elements are located between the outlets of holes for feeding gas into it, and inlets of holes in the bushing on the periphery of the bushing. Elastic baffles are mounted along the longitudinal elements of the cylinder of the bushing.
