Abstract

746,697. Coking coal. BERGWERKSGES. HIBERNIA AKT.-GES. Feb. 17, 1954 [May 8, 1953], No. 4690/54. Classes 55(1) and 55(2). In the coking of coal in coke or like ovens in order to destroy or prevent the formation of ammonia during coking, the upper stratum of the coal in the coking chamber is superficially wetted with a suspension of a metal oxide catalytic contact mass. Suitable oxides are those of iron, aluminium, zinc, magnesium, manganese copper and nickel. In an example an oven containing 20 tons of coal was superficially wetted with a suspension of 2À4 kg. of ferric oxide containing 33À14 per cent iron, the layer thickness of the contact mass increasing towards the rising pipe of the oven. In comparison with a second oven containing untreated charge of coal 95 per cent of the ammonia was destroyed in the oven containing the treated charge.
