Title: Process for the decontamination of exhaust gases
Inventor: SANTIAGO A
IPC: F01N3/18
Filed: 1971-09-10
Abstract: 1355848 Treating exhaust gases ZEUNASTRKER K G 10 Sept 1971 [12 Sept 1970] 42350/71 Heading F1B I. C. engine exhaust gas purifying process consists of the steps of oxidizing the hydrocarbons and carbon monoxide in the exhaust gas in an afterburner, the oxidation of the carbon monoxide being incomplete, so that the proportion remaining is ten times greater than the proportion of nitric oxides in the exhaust gas, and then passing the gas over a catalyst which promotes a reaction between the carbon monoxide and nitric oxides resulting in the formation of carbon dioxide and nitrogen. Fresh air is injected into the exhaust manifold upstream of the afterburner, the quantity being sufficient to allow for complete combustion of the hydrocarbons but to result in the stoichiometrical amount of carbon monoxide to be present to react with the nitric oxides. It is permissible for a small amount of hydrocarbons and a slight excess of carbon monoxide to reach the chamber containing the catalyst, which may also contain 0À5-0À8% oxygen by volume. The catalyst is preferably a granular metal oxide and may be contained in a separate chamber or may be used to line parts of the afterburner chamber which are subject to particularly severe wear. In an example the exhaust gas initially contained, by volume, 4% CO, 0À06% CH and 0À12% NO. After treatment in the afterburner the gas contained 1À5% CO, 0À003% CH and the original quantity of NO, which was subsequently reacted with the CO, the gas ultimately containing 0À3% CO.

Abstract: 1,013,397. Drying fuel. UNITED STATES STEEL CORPORATION. Oct. 28, 1963 [Nov. 8, 1962], No. 42475/63. Headings F4B and F4G. Coal of ¢ inch or less for introduction through the tuyeres of a blast furnace is dried by the top gas from a blast furnace in a fluidized bed drier 10, fed to a sizing screen 21 from which oversize particles are passed to a pulverizer 24 and returned to the screen 21 and particles for use in the furnace are fed to a hopper 23. The gas from the drier 10 passes through a cyclone separator 26, whence the dust is fed to the screen 21, through a scrubber 28, separator 30 and cooler 31 to a pump 34 which feeds it through a drier 38 to a holder 40, where gas is drawn through the coal hopper 23, where it entrains coal dust to the blast furnace tuyeres. Part of the gas is withdrawn after the cooler 31 and used in hot blast stoves or elsewhere. The temperature in the fluidized bed is controlled by passing some of the blast furnace gas direct to the scrubber 28, and the level of the bed is regulated by controlling the flow from the bed through conduit 20. The scrubbed and cooled gas may be purified and preheated before it passes to the gas-holder 40.
