Title: Process for treating petroleum coke
IPC: C21B13/00
Filed: 1963-07-19
Abstract: Petroleum coke particles are activated on their exterior surfaces by treating with an oxidizing gas at a temperature of at least 450 DEG C. for at least 5 minutes, then mixed with a carbonaceous binder, and tempered in an atmosphere containing at least 4% O2 at 200-300 DEG C. for at least 40 minutes. Activation is preferably effected in an atmosphere of steam and air, e.g. 70-85% steam, at 500-700 DEG  C. for 10-30 minutes, or in air at 450-550 DEG  C. for 5-10 minutes, in fluid, fixed, or moving bed, with counter- or non-current flow, or in a rotating drum. The mixture may be compacted, e.g. at 100-200 DEG C. and 10-24,000 p.s.i. before or after tempering.  It may contain 1/2 -1% of MnO, S, MgO, and/or CaO to accelerate tempering, and up to 35% CaO or Fe ore may also be incorporated.  The compact is then calcined or coked, e.g. at 700-940 DEG  C., to give a product of crushing strength greater than 1500 lb./sq. inch and real density 1.05-1.35 g./c.c.  Suitable binders are aromatic tars, coal tar pitch, gilsonite, coking residues, and heavy petroleum residues, e.g. asphalt, used in amounts of 10-25%.  The petroleum coke may be obtained from "delayed", "fluid" or "continuous contact" processes, and should be less than 1/16 inch in size.  The treated coke may be mixed with coal prior to coking or calcining. Examples are described.ALSO:Petroleum coke particles are activated on their exterior surfaces by treating with an oxidizing gas at a temperature of at least 450 DEG C. for at least 5 minutes, then mixed with a carbonaceous binder, and tempered in an atmosphere containing at least 4% O2 at 200-300 DEG  C. for at least 40 mins.

Abstract: 305,112. Chaplin, A. W. C. Oct. 28, 1927. Air, controlling direction of flow of. -Tea leaf, &c. is withered in a manner simulating natural withering in a chamber having openings, provided, if desired, with exhaust fans, in its walls &c. by a current of warm dry air at a pressure slightly above atmosphere. Atmospheric air is drawn through a screen b into a fan c and forced over a furnace f into a transverse or longitudinal duct g which communicates with ducts h having gratings through which the air passes into the chamber in which the tea leaf is supported upon inclined superposed perforate trays l disposed in three storeys in the chamber. The passage of the air over and through the trays is assisted by fans n arranged in openings in the chamber walls. The air not exhausted by the fans n passes through perforations j<1> into the upper storeys of the chamber and is exhausted by fans o disposed in openings in the chamber walls.

Filed: 1926-11-16
Abstract: 261,752. Urquhart, R. M. Nov. 17, 1925, [Convention date]. Fire-extinguishing by foam. - A method of generating foam consists in feeding by suction separately into a flowing stream of solvent dry powdered foam-generating chemicals which enter the stream at substantially the same point. In the apparatus shown, water from a pipe 14 passes through a flaring ejector passage 9 and so to the delivery tube 16. A hopper 1 screwed into a boss 6 on the ejector is divided by a longitudinal partition, not shown, into two chambers containing, for example, dry powdered aluminium sulphate, and sodium bicarbonate with licquorice extract respectively. The partition has an extension 2<1> towards the ejector passage. Reaction between the chemicals is slowly completed in the tube 16, and the nozzle 17 has baffles 18 to assist complete mixing. By turning the hopper so that the partition is transverse to the direction of flow of the solvent an acceleration of foam production is stated to be obtained. The inlets from the hopper chambers to the ejector are so proportioned that the chemicals are fed in the correct reacting proportions.

Filed: 1933-10-20
Abstract: 427,409. Electromagnetic interrupters. DONALDSON, F. G., 14, The Parsonage, Manchester. Oct. 20, 1933, No. 29046. [Class 38 (v)] [See also Group XXXVIII] For giving an intermittent alarm when failure takes place in a circuit, the core of a solenoid is arranged when de-energized to close contacts in its own circuit, and that of the alarm and to open the circuit when energized, the core contacting with and so operating the member controlling the contacts after a certain amount of lost motion. The circuit of the apparatus is shown in Fig. 2 in which the coil a and controlled circuit m are normally connected in series energizing the coil to hold open the contacts j. When the circuit m fails the core a is de-energized closing at j the circuit to alarm l and its own circuit so that the alarm is operated intermittently. As shown in Fig. 1, the core d is pressed by spring e away from the coil a. When the coil is energized, the core moves to the position shown, the plate g after a certain amount of movement contacting with the switch member i to force the member to move with the core and open the circuit between spring blades and conducting ring k. When the coil is de-energized, the core is moved away from the coil by spring e and before reaching the end of its travel the plate g engages the shoulder on member h to move the member to allow springs to be reconnected by conducting ring k. The clearances in the unit are made small and the unit is made airtight to allow the displaced air to slow down the movement and if the current through j is heavy or of high voltage, the whole core may be immersed in oil to give an oil break on the spring contacts.

Filed: 1926-11-19
Abstract: 272,163. Forsen, L. June 3, 1926, [Convention date]. Cements, Portland, treating after manufacture. -Portland cement is obtained in a very finely divided condition in which it reacts quantitatively with water by grinding it together with a harder siliceous substance such as quartz, granite, macadam slag, or quartz sand. The ground cement may be separated from the coarser particles of added material by blast separation methods. If a portion of the added material becomes very finely disintegrated during the grinding, lime is added to react with it, and the advantages of a high lime content are thereby obtained without the deleterious presence of free lime.

Abstract: 340,497. Refining copper. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Harris, J. E. ; 102, Oakland Terrace, Newark, and White, J. H. ; 20, Burchfield Avenue, Cranford, both in New Jersey, U.S.A.) Sept. 30, 1929, No. 29582. Convention date, March 8. [Class 82 (i).] Copper of high electrical conductivity which may be heated in a reducing atmosphere without becoming embrittled is produced by keeping molten pure copper in a vessel lined with a refractory material which is capable of preventing the vessel from giving up to the copper small portions of impurities and adding a deoxidizing agent. The lining may be a substantially pure oxide which is not readily reducible and which adheres to the vessel at the temperature of molten copper. In an example, a crucible 2, made of a mixture of fireclay and graphite, together with its lid 4, is lined with aluminium oxide, partially filled with commercially pure electrolytic copper and placed in an electric furnace 1. 0À1 per cent of calcium boride, preferably in crystalline form, is added just before pouring. Magnesium oxide may be used as a lining and the process may be carried out in a ladle.
