Abstract: 515,928. Destructive hydrogenation. POTTS, H. E. (Naamlooze Vennootschap Internationale Hydrogeneeringsoctrooien Maatschappij). July 11, 1938, No. 20447. Addition'to 459,268. [Class 32] In the process for the production of valuable hydrocarbons by the destructive hydrogenation of carbonaceous materials described in the parent Specification, in which the initial materials are pretreated with sulphur compounds, in particular ammonium sulphide, the initial materials are pretreated with water containing ammonium sulphide which has been formed in the destructive hydrogenation reaction and has been separated from the gases and vapours escaping from the reaction vessel or separator employed therein. The water may be further enriched in ammonium sulphide by injecting it into the pipes of the apparatus in which ammonium sulphide crystals separate off, or by introducing hydrogen sulphide into the water. Brown coal is mixed in finely ground condition in a mixer 2 with 1.5 per cent. ammonium sulphide in the form of water obtained in the destructive hydrogenation of another portion of the same brown coal and fed through line 23. The mixture is dried in a drier 3 and pasted in a mill 4 with an equal weight of heavy oil fed through line 5 and 0.4 per cent. sludge withdrawn from separator 10 and .fed through line 6. The paste together with 3 per cent. Lux mass and hydrogen supplied through line 9 is passed through a preheater 7 to the reaction vessel 8 where it is destructively hydrogenated at 460‹C. and 250 atmos. pressure. The products obtained pass to a separator 10 from which oil-vapours pass to a condenser 11 and separator 12. The condensate is'separated from water in a vessel 15 and the water thus obtained which contains 12 per cent. ammonium sulphide is enriched with further ammonium sulphide to a strength of 18 per cent. and used for pasting coal in the mixer 2. The oil from the separator 15 is distilled in column 19 to give benzine and middle oil which latter is fed through line 21 to the centrifuge 18 in which sludge is separated from the products withdrawn from 'the separator 10.

Title: Improvements in or relating to the preparation and desulfurization of petroleum coke
IPC: C10B55/10
Filed: 1950-08-23
Abstract: 676,494. Desulphurizing coke. STANDARD OIL DEVELOPMENT CO. Aug. 23, 1950 [Sept. 17, 1949; Sept. 17, 1949], No. 20879/50. Class 55 (i). Petroleum coke with a reduced sulphur content, which enables it to be used for metallurgical processes &c., is prepared by rapidly heating the coke to between 2500‹ and 3200‹ F. and holding it at this temperature long enough to effect the desired reduction in sulphur content. The process may be intermittent or continuous. In the former, see Fig. 1, a batch of the coke in a vessel 12 is heated by the combustion of preheated fuel gas and air admitted through pipes 13 and 14, the air being in slight excess so that additional heat is generated by partial combustion of the charge. The discharge gases passing through an outlet 15 carry off a proportion of the sulphur, the batch being removed through a valve 16 when the sulphur content has fallen below 2 per cent, this taking between “ and 6 hours depending on the particle size and the source of the coke. In the continuous process, see Fig. 2, particulate coke is fed through an inlet 11 to a desulphurizing vessel 10 and is heated therein either by hot combustion gases or by partial combustion with air which enters through a pipe 13. The sulphur containing gases discharge through an outlet 12. The desulphurized coke is withdrawn continuously through a water-jacketed outlet 16, part being drawn off through a branch 16<SP>1</SP> to store whilst the remainder passes through a valve 17<SP>1</SP> into a coking drum 19 into which the preheated residual oil or crude oil which is to be converted into coke is sprayed, through an inlet 20. The oil carbonizes on the hot coke particles which are withdrawn, when sufficiently coated with fresh coke, through an outlet 24 on to a screen 25, the coarser particles being withdrawn through an outlet 27 for crushing prior to recycling whilst the finer coke is elevated directly through line 29 to the inlet 11 of the desulphurizer.

Filed: 1919-08-26
Abstract: 155,875. Broadbridge, W., Edser, E., Stenning, W. W., and Minerals Separation, Ltd. Aug. 26, 1919. Surface-tension separating-processes.-Coal briquettes are made from coal concentrates, which may be obtained by treating impure coal, coal dumps, and the like by froth-flotation processes, by obtaining a suspension of the powdered concentrates in water and subjecting to agitation with a liquefied binding-agent, whereby the coal particles are coated with binding medium and flocculated so as to be readily separable from the water. A flocculating agent, such as slaked lime, or sodium silicate. may be added to the pulp of coal concentrates in water and may act also as an auxiliary binding agent. The liquefied binding-agent may be melted pitch with or without tar, resin, and the like, and a liquid agent which contains or yields both a frothing-agent and a binding-medium may be used. The agitation of the coal-water pulp with the binding-agent is carried out with a greater or less degree of aeration. The concentration of the coal by the frothflotation process and the coating of the coal particles with the binding medium may be combined into a single operation, which may be continuous. The amount of pitch used may be seven per cent of the weight of the coal reckoned dry, or five per cent of pitch may be used together with cresol and kerosene oil. Specifications 26295/02 and 7803/05 are referred to.

Abstract: 744,400. Digital electric calculating apparatus. STANDARD TELEPHONES & CABLES, Ltd. May 21, 1952, No. 21248/54. Divided out of 744,352. Class 106 (1). Apparatus for converting a number expressed in a first notation into a second notation, comprises, a storage circuit for the number in the first notation, a circuit supplying pulses to the storage circuit, each pulse reducing the stored number by unity, a counter operating in the second notation to count pulses produced in synchronism with the first pulses by a second pulse supply circuit, and means responsive to the number in the storage circuit reaching zero, to stop the supply of pulses to the counter. In the described embodiment a binary series-mode pulse train representing the number to be converted, enters on a line CML and is staticized in a series of two-state devices (e.g. gas-discharge tube trigger pairs) M1, S1, M2, S2 ... under the control of successively-opened gate G33, G35 ... Each two-state device is changed from a zeroized S-element conducting state to the upper M-element conducting state whenever a binary " 1" is to be registered. At the conclusion of the entry operation SZ is operated and a gate G41 opens to energize STB and start a generator of pulses CVP which are applied both to the binary chain of elements M1, S1, M2, S2 ... and to a decimal counter comprising decades PCU, PCT, PCH ... which may be multicathode gas discharge tubes. The arrangement of gates in the binary chain causes the number registered therein to be reduced by unity for each CVP pulse applied to it, while the decimal counter advances from zero until the decimal equivalent of the initial binary quantity is accumulated therein. At this point all stages of the binary chain have the sections S1, S2, S4 ... conducting and this causes a gate G54 to be opened and the pulse generator to be stopped.
