Abstract
1460615 Cracking OSAKA GAS CO Ltd 16 April 1974 [18 April 1973] 16687/74 Heading C5E Heavy hydrocarbons are cracked in a fluidized bed of granular solid particles in a reactor by supplying a gas containing at least 5% of hydrogen to the bottom of the reactor at a temperature of at least 500‹ C., supplying heavy hydrocarbons and granular solid to the top of the reactor to maintain the temperature there not above 550‹ C., and drawing off cracked gas and vapours from the top and granular solid and coke deposited from the bottom. Preferably the granular solid is coke, but alumina, silica or zirconia can also be used. As shown, heavy hydrocarbons, granular solid and hydrogen are supplied by lines 1, 2 and 3 to reactor R 1 . Cracked gas and vapours are taken off by line 4, cooled at A and separated into gas and liquid phases at B. The separated gas may be taken off by line 6 or recycled by line 12; the liquid is taken off by line 7, or part of it may be recycled by pump P and line 8 as a further control of temperature. The granular solid with coke deposited on it is taken off by line 9 to a second reactor R 2 , to which are supplied steam and oxygen by lines 21 and 22 to burn off coke. Decoked solids can be taken off by line 34 or recycled by line 33. Gas from the regenerator (mainly CO and H 2 ) is taken off by line 23 and scrubbed at D, the slurried coke from the scrubber being recycled by line 25. The scrubbed gas is taken by line 27 to a converter F where CO is oxidized to CO 2 and then by line 28 to tower G, where CO 2 and H 2 S are absorbed. The gas is now mainly hydrogen and may be taken off by lines 29 and 31, or taken through compressor C and heater H to provide the hydrogen needed in reactor R 1 . The oil in line 7 can be further hydrocracked or hydrodesulphurized, using hydrogen from the line 31. The heavy oil to be cracked may be a crude or residual oil. The hydrogen may be substantially pure or mixed with methane, ethane, ethylene, steam or CO 2 .
