Title: Process for the Hydrogenation of Coal
Inventor: DENT FREDERICK JAMES
IPC: C10B49/08
Filed: 1966-10-06
Abstract: 1,154,322. Coking coal. GAS COUNCIL. 6 Oct., 1967 [6 Oct., 1966], No. 44733/66. Heading C5E. Methane - containing gas is made by introducing powdered raw coal into a recycling bed of non-coking material at 600‹ to 1000‹ C. fluidized by an hydrogenating gas suitably at a pressure of 10 to 200 atmos., the rate of introduction of the coal into the bed being such that the coal is rapidly heated, at least partially hydrogenated, and converted to a non- coking condition. The residue of non-coking powdered char may be subsequently hydrogenated under more severe conditions to produce more methane and a residue which may be used for hydrogen manufacture. Inside the cylindrical reaction vessel 3 is a cylinder 4 mounted coaxially and spaced from a shorter cylinder 5 by a gap 6. The fluidized solids are caused to circulate up the cylinder 4 and down the annulus between 3 and 4 by passing most of the hydrogen through the pipe 10 into the chamber 7 and thence into the central tube 4. A smaller amount of hydrogen is passed through the pipe 11 to fluidize the descending solid particles. To start the process the bed is formed from a non- coking fluidizable solid, e.g. high or medium temperature coke, which is gradually displaced as the bed is continuously withdrawn through pipe 14 while powdered coal is fed to the bed, through pipe 12, entrained in gas. Both the coal and the hydrogen may be preheated. Additional heat may be obtained by simultaneously carrying out other reactions in the bed, e.g. an oxygen containing gas may be added or a light petroleum distillate can be fed and hydrogenated.

Abstract: 1,036,527. Valves. ACF INDUSTRIES Inc. Nov. 23, 1964 [Dec. 2, 1963], No. 47633/64. Heading F2V.  A valve comprises a body 12, Fig. 1, a slidable gate member 30 having planar sealing surfaces 34 and a through passage 32, seating means 20 to engage the planar surfaces, valve guide means 176, Fig. 7, carried by the seating means and having vertically disposed flanges 182 for preventing excessive lateral movement of the gate, means 184, Fig. 10, on the guide flanges for preventing movement of the guide member in an outward axial direction relative to the body, and means 188 for preventing inward axial movement of the lower portion of each guide member. Each seat assembly is slidably mounted in a recess 70 and forms a press fit with a separable portion 82 retaining a sealing ring 94 of natural or synthetic rubber in a groove 88 so that a portion of the ring protrudes to engage the gate. Alternatively, the ring may be held between inner and outer separable portions having their sealing faces surfaceground after assembly on the seat. A back face sealing member 122 is placed radially outside the ring 94 to provide a fluid pressure differential urging the upstream seat into sealing contact with the gate. A bleed port 29 permits the seats to be tested for fluid tightness with the valve in service. If the pressure in the valve chamber exceeds the upstream line pressure, for example, due to heating of a volatile liquid, when the valve is closed, the upstream seat assembly is displaced axially into its recess and the resulting clearance between the ring 94 and the gate permits the excess pressure to be relieved. If the sealing rings, are destroyed, for example by fire, the gate effects a metal to metal seal with the downstream seat assembly. The valve spindle 36 has a collar 58 engaged by thrust bearings 56 adjusted by nuts 62, 64 and is provided with a packing chamber into which semi-solid material may be forced through a fitting 69. To cause axial displacement of the gate, threads 42 co-operate with a nut 38.
