Title: Process for the preparation of hydrocarbon oils, entirely or substantially entirely freed from mercaptans
IPC: C10G27/08
Filed: 1961-07-03
Abstract: A hydrocarbon oil entirely or substantially entirely freed from mercaptans is obtained by treating a mercaptan-containing hydrocarbon oil with one or more copper compounds, preferably in the presence of oxygen, and then subjecting the oil, which is now freed from mercaptans, to an after treatment with an absorbent impregnated with hydrochloric acids to wholly or substantially eliminate traces of copper compounds.  The absorbent, for example activated carbon, silica gel, pumice, or fuller's earth, may be in the form of a contact bed.  The treating temperatures may be 20-65 DEG  C.  The copper compound is preferably cupric chloride, with or without sodium or ammonium chloride, and the used material may be regenerated by treating with an oxygen containing gas or a peroxide or ozone.  In one form, the oil is passed together with oxygen from the top to the bottom of a single column filled with activated carbon, the top containing the copper compound and the bottom being impregnated with hydrochloric acid.  Prior to the above treatment the oil may be treated with a caustic alkali solution to eliminate hydrogen sulphite and other acid compounds, and/or with an absorbent impregnated with hydrochloric acid to remove traces of metal compounds.

Title: Improvements in or relating to the distillation and carbonisation of coal-oil mixtures
IPC: C10B55/02
Filed: 1934-08-29
Abstract: Unsaturated hydrocarbons produced in the heat treatment of mixtures of coal and like carbonaceous materials with oils to produce coke and light hydrocarbons, are passed through a scrubbing tower employing permanganates as scrubbing medium, to oxidize the unsaturated hydrocarbons to glycols.ALSO:<PICT:0448028/III/1> <PICT:0448028/III/2> Coke and hydrocarbons, particularly olefines and aromatic compounds, suitable for use as motor fuels and as solvents, are obtained by mixing coal or other solid carbonaceous material with oil, stirring the mixture while heating it to 100--325 DEG  C., coking the mixture in a stationary retort at 425--600 DEG  C., cooling the gases and vapours obtained, and passing the gases through refrigerating devices in combination with electric precipitators or scrubbers, back pressure in the apparatus being prevented by application of a suitable negative pressure.  Coal fed from a hopper 2 is mixed with oil, preheated by a steam coil in a vessel 7, in a vessel 5 and the mixture is fed to a vessel 14 provided with a stirrer 15 where the mixture is heated to 325 DEG  C.  Vapours pass off through a reflux condenser 16, maintained at such a temperature that vapours boiling above 200 DEG  C., are refluxed to the vessel 14, to a fractionating tower 18 having upper and lower packed sections 25, 26.  The heated mixture is passed into a coking chamber 21 heated to 550 DEG  C., which may be provided with a removable steel tray, where the mixture is reduced to coke, and the gases and vapours evolved are passed through a line 22 into the column 18 from which reflux is recycled through a cooler 28 to the vessel 7. Alternatively the gases and vapours may first be passed through a catalyzing chamber 56, Fig. 2 maintained at 550 DEG  C., and filled with semi coke, zinc, dust, or alkaline earths. Vapours and gases pass off from the top of the column 18 through a condenser 32 and the condensate is collected in receivers 34.  The gases pass on to a refrigerator 48 maintained at -40 to -140 DEG  C., where a distillate is condensed and collected fractionally in pressure receivers 49--51. The gases finally pass through an oil scrubber 53 and a caustic soda washer 54 reduced pressure being maintained by a pump 55. Alternatively the gases may be passed through (1) an electric precipitator, (2) a wet scrubber employing gas oil, creosote oil, paraffin wax tailings or the 150--200 DEG  C., fraction obtained in the process which may be recirculated through the scrubber, (3) a scrubbing tower in which the crude oil used for mixing with the coal is used as absorbent, the saturated oil being heated in a coil and passed into a receiver from which the absorbed fractions are distilled off and then conducted to the crude oil storage tank.  The gases may also be passed through a permanganate scrubbing tower to oxidize the unsaturated compounds to glycols.

Abstract: 1435425 Micro-suspension polymerization of vinyl chloride RHONE-PROGIL SA 5 June 1974 [8 June 1973] 24940/74 Heading C3P A method of homo- or co-polymerizing vinyl chloride in microsuspension which comprises polymerization of the monomer or monomers in micro-suspension in the presence of a seeding product in the form of particles of the vinyl chloride homopolymer or copolymer prepared by micro-suspension polymerization, which particles contain all of the organo-soluble initiator necessary for the polymerization, and in which the initiator is activated by the presence of an organo-soluble metallic complex produced in situ throughout the polymerization reaction system by reacting a water soluble metallic salt present in the polymerization system with a complexing agent that is capable of causing the metal to change from its water-soluble form to a form soluble in vinyl chloride, that has no inhibiting action on the polymerization or on the activation of the initiator, and that is progressively introduced throughout the course of the reaction. In a modification of the process the complex per se may be progressively introduced throughout the course of the reaction. The metal of the organo-soluble complex may be Fe, Cu, Co, Ni, Sn, Zn, Ti, V, Mn, Cr, or Ag and the complexing agent may be a monocarboxylic acid, a polycarboxylic acid, an alkyl phosphoric acid, lactone, ketone, or carbazone capable of causing the metal to change from its watersoluble form to a form soluble in vinyl chloride and having no inhibiting action on the polymerization and on the activation of the initiator, e.g. sulphosalicylic acid, naphthenic acid, octanoic acid, succinic acid, tartaric acid, maleic anhydride, di(2-ethyl)hexylphosphoric acid, ascorbic acid, γ-butyrolactone, benzoin, ascorbic acid, acetylacetone, or diphenylthiocarbazone.

Abstract: 764,008. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1954 [Oct. 2, 1953], No. 24951/54. Class 40(6) A synchronized pulse generator comprises a regeneratively coupled pair of electron discharge tubes having a time constant network in the grid circuits of one tube to which the synchronizing signals are applied to trigger the tube the output of the tube being regeneratively fedback to its grid circuit via the second tube. The arrangement is such that the period during which the oscillator is sensitive to triggering signals is reduced so that unwanted bridging by noise pulse is less likely to occur. Figs. 1 and 2 show the application to the frame synchronizing signal generator of a television receiver in which the frame sychronizing signals are applied at input 1 to the time constant circuit 4 in the grid of tube 7 the output from tube 7 being amplified in tube 13 and regeneratively coupled back via transformer 5 to the grid of tube 7. The triggering pulses, Fig. 2D, cause tube 7 to conduct earlier than would otherwise be the case in the free-running condition and to draw more current. As a result the pulse output of tube 13 and thus the grid current flow in tube 7 are increased so that the charge on capacitor 3 is increased as shown at 30 in Fig. 2E than for free running operation 20, Fig. 2E. Due to the increased charge on capacitor 3 the circuit is less liable to triggering by unwanted noise pulses and the stability of the oscillator is increased.
