Abstract

1398078 Reducing gas IMPERIAL CHEMICAL INDUSTRIES Ltd 25 Sept 1972 [5 Oct 1971] 46228/71 Heading C5E Reducing gas is made by reforming a hydrocarbon feedstock with an excess of steam in an externally heated catalyst bed, cooling the resulting reforming gas, condensing and removing at least a portion of the unreacted steam, reheating the dried gas to 750-1100‹ C. and reacting carbon dioxide and unreacted steam contained in the gas with hydrocarbon contained therein or added thereto. Suitable hydrocarbon feedstocks are methane, refinery off-gas, ethane, propane, butane and naphthas boiling up to 350‹C. which should first be hydrodesulphurized with a bed of nickel molybdate-on-alumina catalyst and with a bed of zinc oxide-sulphide adsorbent. The reforming can be carried out with a refractory-supported nickelzirconia catalyst at up to 50 atmospheres using a steam-carbon ratio of 1À35 to 5. The dried reformer gas can be reheated (a) within a bed of catalyst effective for the reaction of hydrocarbon with steam or carbon dioxide, or (b) by partial combustion of hydrocarbons either present in the reformer gas or added as methane, naphtha or fuel oil. The reheated, dried reducing gas can be used in blast furnaces, shaft furnaces, pellet reduction furnaces and fluidized bed reduction furnaces to reduce metal ores, e.g. to iron; the used gas can be recycled to the reforming stage and the hot reduced ore charge can be used to reheat the dried reformer gas. As shown desulphurized natural gas is mixed at 14 with steam from a boiler 10 and the mixture is preheated at 16 by flue gases and passed through tubular catalyst beds 18 in a radiant furnace 20 fuelled by natural gas. The reformer gas, e.g. at 850‹ C., is cooled in an indirect gas/ gas heat exchanger 22, then in a boiler 24 and then in an air cooled condenser 26 (alternatively the final cooling at 26 can be by direct contact with water). The condensed water is separated from the reformer gas at 28 which is then reheated at 22, after the addition of more natural gas at 30, and finally in the tubular catalytic beds 32 to a final temperature of 950-1000‹ C.
