Title: Improvements relating to desulphurisation catalysts
IPC: C10G45/08
Filed: 1951-02-23
Abstract: A trihydrate bauxite which has been heated for at least two hours at about 550 DEG  C. and which after heating has a surface area greater than 120 sq. m./gm. is used as a carrier for a catalytic agent comprising a mixture of oxides of cobalt and molybdenum or a compound of cobalt, molybdenum and oxygen or a mixture of one or both of said oxides with said compound, in the desulphurization of petroleum hydrocarbons.  The MoO3 content should be in the range 1-15 per cent., preferably 5-12 per cent. by weight and the CoO in the range 0.2-3 per cent., preferably 1-2.5 per cent. by weight.  The catalysts of the invention are stated to be some 20 per cent. denser than alumina-based catalysts.  In the examples, the catalysts are prepared by impregnating a bauxite, previously dehydrated by roasting at 550 DEG C. for two hours, with an ammoniacal solution containing cobalt nitrate and ammonium molybdate, filtering or draining, drying at 150 DEG C. and roasting at 550 DEG C. for two hours.  In the first example, the catalyst was used to desulphurize a gas oil at 760 DEG F. and 50 p.s.i.g. in the presence of hydrogen at a rate equivalent to 150 cu. ft. per barrel of gas oil.  In the second example an Iranian gas oil of specific gravity 0.8635 at 60 DEG F. containing 1.14 per cent. of sulphur and having a boiling point in the range 493-674 DEG F. was passed downwards over a bed containing 520 ml. of catalyst at a rate of 1040 ml. per hour at 780 DEG C. and 100 p.s.i.g.  The catalyst was treated with hydrogen at 780 DEG C. and 100 p.s.i.g. prior to the experiment and initially hydrogen at a rate equivalent to 4,000 cu. ft. per barrel was added to the gas oil. Subsequently hydrogen was provided by recycling a portion of the gaseous product.  In a third example a Kuwait crude oil was hydrofined.  Details are given. Specifications 654,152, 663,038, 669,536, 669,552, 669,553, 669,951, 697,222, 697,227, and 697,724 are referred to in connection with autofining.

Title: Process for the extraction of mercury from gases
IPC: B01D53/64
Filed: 1974-02-04
Abstract: 1417541 Removal of mercury from gases PREUSSAG METALL AG 4 Feb 1974 [5 Feb 1973] 05047/74 Heading C1A A gas stream is freed from vapour of free or combined mercury by reacting the mercurycontaining gases, in the presence of SO 2  and condensing H 2 O vapour, with nascent sulphur formed from H 2 S or a compound that generates H 2 S, to form solid mercury sulphide which is then precipitated from the gases. The H 2 S may be formed by adding a sulphide, e.g. sodium sulphide, to the gas stream. The gas may be at 10-70‹ C. when the mercury sulphide is formed. The precipitate may be removed by washing, with or without the aid of wet electro-filters. Any colloidal HgS formed is removed by adsorbing on to a solid substrate and precipitating as before. The precipitates are processed to yield metallic mercury. Sulphuric acid prepared from the SO 2  thus purified has a considerably lower mercury content than H 2 SO 4  not so prepared, e.g. 0À5 p.p.m. compared to 60-80 p.p.m. In one embodiment (Fig. 1), gas at 1000‹ C. from the roasting of sulphidic zinc ore in a furnace (2) is cooled progressively in units 3 and 6 to a temperature of 50-70‹ C., and finally to 30-40‹ C. in unit 9. Dust is precipitated in the cyclone 4 and a hot gas electrofilter (5); the filtered gas is then washed with recycled dilute H 2 SO 4  solution in washing tower 7. Injection of H 2 S or a source thereof, e.g. Na 2 S, at 14, produces HgS particles which are precipitated in the wet electro-filters 8 and 10.

Title: Automatic sprinklers for fire extinguishing
IPC: A62C35/64
Filed: 1926-02-23
Abstract: 248,008. Meissner, F. Feb. 23, 1925, [Convention date]. Sprinklers, automatic; sprinkling apparatus, non-automatic.-The water valve of an automatic sprinkler is opened by the expansion of air in a bulb on a ceiling acting through a relay valve. The upward pressure on the valve 15 closing the water main 4, Fig. 2, is equalized by a weight 20 and by water pressure in the chamber 14 above the valve, transmitted by a nozzle 11 and pipe 19. The chamber 14 communicates, by a passage 13. Fig. 3, with the open end of a glass tube 8 in a chamber 9 below a valve 6. When the air in a bulb 1, Fig. 1<a>, expands on heating, it transmits pressure by a tube 2 to a diaphragm 3 and lowers the valve 6 against an adjustable spring 7, the valve 6 breaking the tube 8. Water can now flow from the chamber 14 to the chamber 9 by way of the tube 8, thus reducing the pressure on the upper side of the valve 15 so that the latter lifts and water flows freely by an annular chamber 16 to the sprinkler pipe 17. The sprinkler may be operated manually by a valve 24 which, when opened, allows water to flow from the chamber 14 by way of a pipe 23. The valve 24 is protected from contact with water by a seal 25 which it breaks on opening. The pipe 23 may be provided with safety fuses 27, Fig. 1<a>, which melt in the event of fire and allow water to flow from the chamber 14. A manually operated cock 33 may be provided in the sprinkler pipe 17 for testing purposes. The handle 34 of this cock is so arranged that the cock must be turned to service position before the door of the apparatus casing can be closed.
