Patent GB-986428-A (GB)
IPC: B07B1/00
Filed: 1961-07-28
Abstract: 986,428. Washing granular material; spray producers. STAMICARBON N.V. July 28, 1961 [July 30, 1960; Sept. 16, 1960], No. 27550/61. Headings B2F and B2H. Coal is washed free of magnetite, which was used in suspension to free the coal from shale, by rinsing it with streams of water while it is supported on a screen, the kinetic energy of the water streams being insufficient to disturb the coal and its quantity being insufficient to form pools on the screen. As shown in Fig. 1, the coal is moved as a bed along a reciprocated screen 2 and rinsing water is provided from above by an apertured tank 4 the level in which is controlled by a float valve 6 and 7. The rinsing water leaves the tank through apertures 11 and flows on to plates 12, see Fig. 2, where it is broken up by corrugations 14 to form thin trickles 17. Instead of forming the corrugations in the sheet 12 a separated corrugated sheet may be welded underneath the sheet 12. In place of corrugations the sheet 12 may have a saw-tooth edge. The screen has ribs 3 at intervals along its length to provide a minimum of relative motion between the coal particles. Instead of ribs the screen may be in steps, preferably rounded to allow the coal to fall over smoothly. Fig. 5 shows the diagram of a process of separating coal from shale with the use of a magnetic suspension and means to recover the magnetite. Coal containing shale is fed at A, with a magnetite suspension at B, into a mixing tank 21 from which the mixture is fed to a cyclone washer 23 which separates the coal and shale fractions into paths 24 and 25, respectively. The coal is shot down a curved screen 26 of the kind described in Specification 791,520 and hoppers 27 and 29 collect very fine coal and undiluted magnetite suspension which is recirculated from a tank 32 back to the mixing tank 21. The coal with adhering magnetite particles is now rinsed on a reciprocating screen 34, as described above with reference to Figs. 1 and 2, and the clean coal is extracted at C. Sprinklers 35 and 36 are employed with pure water supplied from a main W. Sprinkler 36 receives nothing but pure water and gives a final rinse. Sprinkler 35 also consumes recirculated water. The diluted magnetite suspension and fine coal collected beneath screen 34 is shot on to a further curved screen 39 and passes to a magnetic separator 41 which has an output of coal at D and of magnetite at 43. The dilute magnetite suspension is thickened in a trough 45, water overflowing from this trough being recirculated to the sprinkler 35 and the thickened magnetite suspension being recirculated to the mixer 21. Shale ejected from the cyclone washer at 25 is treated in the same way as the coal to reclaim the magnetite suspension. The necessary plant is a duplicate of that employed for the coal and is shown with the same references and a superscript dash.

Title: Improvements in conducting endothermic fluidised catalytic hydrocarbon reactions
IPC: B01J8/18
Filed: 1955-09-28
Abstract: <PICT:0789834/IV (b)/1> In order to supply heat to a hydrocarbon hydroforming reaction carried out in the presence of a fluidized bed of catalyst, a stream of catalyst is withdrawn from the reaction zone 1 and passed via pipe 16 to heat exchanger 7 where it is contacted indirectly with hot combustion products of a fuel burned with air at substantially atmospheric pressure, the heated catalyst is returned to the reaction zone via pipe 21, and the combustion products pass from heat exchanger 7 via pipe 16A to economizer 5 where they heat the hydrocarbon fed to the reaction zone.  More than 70 per cent of the heat required in the reaction zone may be supplied to the catalyst in heat exchanger 7.  Suitable hydroforming catalysts comprise a Group V, VI or VIII metal oxide or sulphide (e.g. molybdenum oxide) on alumina, or a noble metal, e.g. platinum, on alumina.  From 1500 to 4000 standard cubic feet of hydrogen may be changed to the reaction zone per barrel of oil. In heat exchanger 7 the catalyst passes upwardly through tubes 17 which are surrounded by hot combustion fumes.  In a modified form of heat exchanger, Fig. 2 (not shown), the tubes are immersed in a fluidized bed of inert solids, combustion of the fuel taking place in the fluidized bed.ALSO:<PICT:0789834/III/1> In order to supply heat to an endothermic hydrocarbon reaction carried out in the presence of a fluidized bed of catalyst, a stream of catalyst is withdrawn from the reaction zone 1 and passed via pipe 16 to heat exchanger 7 where it is contacted indirectly with hot combustion products of a fuel burned with air at substantially atmospheric pressure, the heated catalyst is returned to the reaction zone via pipe 21, and the combustion products pass from heat exchange 7 via pipe 16A to economizer 5 where they heat the hydrocarbon fed to the reaction zone.

[Also in Divisions F2 and G3] Pressure fluid for steering a vehicle in right and left turns is delivered through respective outlets 34, 32 of a valve device 18 which is supplied through an inlet 30. The steering shaft 92 is threadedly engaged in the power operating piston 46 and carries two sleeves 98, 100 mounted between thrust bearings 110, 112. These sleeves clamp between them by apertured lips 132, 134 the inner periphery of a valve disc 63. Ends 120, 122 of the sleeves provide movable valve seats. Fixed sleeves 64, 66 radially spaced from the sleeves 98, 100 provide further seats. In the neutral position shown fluid is returned from both outlets to a sump connection 36 through the interior of the sleeves and pressures on the piston 46 are equalized through lines 56, 60. On movement to the right the valve disc 63 is flexed so that the right turn outlet 34 is isolated from the supply and remains connected to sump whilst the left turn outlet is isolated from the sump. The unequalization of pressures on piston 46 returns the valve to neutral position. The resistance of the disc to flexure provides " feel."

Abstract: 749,823. Agglomerating ores; reducing iron ores. STEWARTS & LLOYDS, Ltd. Dec. 23, 1953 [Nov. 10, 1952], No. 28221/52. Classes 72 and 82(1). A method of producing iron from its ores in a blast furnace, whereby the final composition of the iron is controlled and in which at least a proportion of the burden consists of pelletised ore comprises pre-heating a proportion of the pellets, then adding the pre-treated pellets to the rest of the burden and subjecting the whole to blast furnace treatment. The pellets are made by reducing ore fines to preferred size grading, wetting the graded fines as necessary, subjecting the wetted fines to mixing and to vacuum or other treatment to remove occluded air, extruding the mixture and sub-dividing the extrusion into pellets. The pre-heating may be effected to modify the percentage of sulphur in the pellets in which case it takes place in an oxidising atmosphere at a temperature between 1175‹C. and 1250‹C. or to vary the percentages of ferrous and ferric iron in the ore in which case it takes place in the appropriate oxidising or reducing atmosphere at a temperature between 900‹C. and 1100‹C. In manufacturing the pellets ore fines 1, to which may be added lime, limestone or other flux or enriching material such as scale, high grade ores, ore concentrates or scrap metal, with or without carbon in the form of, for example, flue dust or coke breeze 2, are ground and plasticized in a pan-mill 3, if necessary with the addition 4 of water or dilute acid or alkali and are screened 6, if need be, with the oversized material 6A, returning to the pan-mill via 3A. The screened material 6 proceeds either directly to a mixer 8 where provision is made for the addition 9 of water and also materials as at 2, or via a chamber 7 in which the moisture content is reduced. The mixed and pugged material proceeds into the first scroll 10 of the conveyer 11, which may be surrounded by a heating element 12 and then, through a plate or cone shredder 13, into a reduced pressure chamber 14 from which it is removed by a scroll 15, extruded through the die 17 and cut off at 18. A rotating drum 19 may be provided to remove from the pellets any sharp edges caused in the cutting operation. The pellets then proceed to the curing chamber 20 wherein a humid atmosphere may be caused 21, together with an elevated temperature by heaters 22 and wherein the pressure may be varied by the pressure fan 23 or vacuum fan 24. After curing, the pellets may be stored in suitably humid containers 25 or proceed to the point of usage.
