Title: Flameless reaction of gaseous or vaporous saturated hydrocarbons to form olefines
IPC: C07C4/02
Filed: 1956-08-09
Abstract: Olefines are produced by the partial oxidation of gaseous or vaporous saturated hydrocarbons having at least two carbon atoms in the molecule wherein water vapour is added to the oxidizing gas prior to mixing with the hydrocarbon, whereby flame formation in the mixing chamber is prevented.  The amount of water vapour necessary may be discovered by passing the hydrocarbon and oxidizing gas into the mixing chamber and adding steam to the oxidizing gas until the flame is carried out of the mixing chamber.  Steam may also be added to the hydrocarbon provided that the volume ratio of steam to oxygen in the oxidizing gas is greater than that of steam to hydrocarbon in the hydrocarbon - containing gas.  Conditions of 600-1000 DEG  C. at atmospheric, increased or reduced pressure may be used, in the presence, if desired, of a fluidized bed of an inert solid material. In an example, 120 normal cubic metres of propane and 51 normal cubic metres of oxygen to which is added an equal volume of steam are preheated to 600 DEG  C., mixed and reacted in a fluidized bed of sillimanite at 795 DEG  C. and atmospheric pressure.  The product contained by volume, 23 per cent ethylene, 7.6 per cent propylene, and 30 per cent other hydrocarbon, mostly methane, together with oxides of carbon and hydrogen.

Title: Improvements in and relating to the production of hydrogen-containing gases from hydrocarbons and steam
Inventor: HOLROYD RONALD
IPC: C01B3/30
Filed: 1951-10-26
Abstract: A hydrogen-containing gas is continuously produced by bringing a mixture of steam and a hydrocarbon which is normally gaseous or liquid into contact, in a gas-producing stage, with a bed of particulate solid carbonaceous material being circulated in a system consisting of a gas-producing stage and a heating stage. Gas, e.g. hydrogen, carbon monoxide or nitrogen or the gas produced in the process, may be used if desired as a carrier, with a vaporized liquid hydrocarbon.  The temperature in the gas-producing stage is preferably 900-1,000 DEG  C., temperatures below 900 DEG  C. giving a larger proportion of unsaturated hydrocarbons.  In the example, 920 DEG  C. was maintained.  Heat may be supplied to the heating stage by external heating or by combustion of a part of the carbonaceous material, e.g. in a fluidized or entrained state, by passing an oxygen-containing gas therethrough.  Hydrocarbons containing paraffin and/or unsaturated and/or aromatic components may be used, particularly hydrocarbons containing saturated paraffins with 2-4 carbon atoms per molecule, mineral oils and residues from the refining of such oils and from the treatment of coal tar.  Coal, coke and intermediate products may be used as the carbonaceous material. Specification 644,004, [Group XII], is referred to.

Filed: 1957-08-12
Abstract: Polyethylene film is heated to a deformable state below its melting-point and embossed by an embossing roller and simultaneously printed with a colouring material, the latter being deposited on to the valley surface of the film.  As shown, polyethylene film from a supply roll 12 may be fed over carrier rolls 12 disposed below heating elements 38, e.g. electric lamps, coils or gas burners.  The effect of heating elements 38 is to bring the polyethylene film into a deformable state before it passes <PICT:0860895/IV (a)/1> between resilient impression roller 20 and embossing die roller 23.  A colouring material, e.g. printing-ink, may be supplied to the crest of roller 23 from tank 26 via matching roll 28, doctor blade 30, roller 32, and roller 35.  The polyethylene film may subsequently be passed over cooling drum 40 before being collected on roll 43.  The deformation of the polyethylene film by heating elements 38 may produce a somewhat oxidized surface giving the film a greater receptivity for, e.g. printing-ink.

Patent GB-1103314-A (GB)
Title: Foamed oxymethylene polymers
IPC: C08J9/28
Filed: 1965-06-17
Abstract: A cellular oxymethylene polymer product is prepared by dissolving the solid polymer in a volatilizable liquid and then evaporating the liquid so as to precipitate the polymer while causing a dispersion of gaseous or vaporous bubbles to be trapped in the solidifying polymer. Preferably the liquid is a solvent for the polymer only at temperatures above its boiling point at normal pressure, the solution being formed under pressure and the pressure being suddenly released to cause rapid volatilization of the liquid.  Suitable solvents are alcohols containing 1 to 20 carbon atoms, ketones, alkanolamines, esters and ethers, optionally in mixture with water.  The volatilization of the liquid can also be effected by bubbling an inert gas through the solution, the gas being trapped by the solidifying polymer. Preferred polymers are those containing 0.4 to 15 mole per cent of oxyethylene groups distributed among the oxymethylene groups which form the major part of the polymer, e.g. a copolymer of trioxane and approximately 2 weight per cent ethylene oxide. In examples, methanol, ammonia and water are used and nitrogen as the inert gas.
