Patent GB-369958-A (GB)
Title: Recovery of sulphur
IPC: C01B17/04
Filed: 1930-09-25
Abstract: In the formation of sulphur by reaction between sulphuretted hydrogen and sulphur dioxide in the presence of a catalyst, a mixture of adsorbent materials is used as the catalyst, such a mixture preferably being composed of activated carbon and a mineral gel, e.g. silica gel or a zeolite; the preferred proportions are two of carbon and one of mineral gel.  In forming the catalyst, the carbon employed is produced by distilling wood, coal or lignite below 600 DEG  C. and treating with steam or air.  The finely divided carbon is first mixed with one of the components of the gel and then the other is added. After the gel has formed, the catalyst is washed, dried at a low temperature and granulated. Alternatively, the components may be mixed and the carbon added before the gel is formed.  For silica gel, a 7 per cent solution of water-glass is neutralized with sulphuric or hydrochloric acid and the carbon mixed therewith; for a zeolite gel, a 3 per cent solution of sodium aluminate is added to the water-glass.  Air and other gases may be removed from the carbon particles to permit the gel to enter the carbon pores. Alternatively, carbon may be deposited in the pores of the mineral gel.  In carrying out the reaction, free oxygen need not be removed from the sulphur dioxide which may be derived by smelting sulphide ores and the sulphuretted hydrogen by treating the matte with an acid.  The granulated catalyst is formed into beds through which the gases are passed, the deposited sulphur being removed by steam or superheated water, or by a solvent.  The Specification as open to inspection under Sect. 91 (3) (a) states also that the mixed catalyst may be formed under reduced pressure, and the use of the catalysts is claimed for chemical reactions generally.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the method of and apparatus for drying materials in bulk, especially applicable to the dehydrating of wet peat
IPC: F26B21/00
Filed: 1938-10-03
Abstract: 512,204. Drying peat &c. WHITFIELD, C. Oct. 3, 1938, No. 28696. [Class 34 (ii)] Wet peat &c. is subjected to a progressively increasing temperature in a current of inert gas moving in the same direction as the peat, the increasing temperature being obtained by superheating the resulting moisture-laden gases and passing them through the treatment zone in counterflow to, and out of contact with, the peat. Thus, blocks of wet peat may be stacked on trucks provided with rear walls 22 and moved step by step through a tunnel having longitudinal baffles, e.g., Fig. 2, defining side compartments containing heating tubes 28 connected to end headers, and ribs 23 extending across the top of the tunnel and down the sides thereof between the outer walls and the baffles. The drying is effected by the combustion in a chamber 32 of the gases generated in a producer 30, e.g., of the kind described in Specification 342,646, [Group XII], the products passing through a dust 34 into the feed end of the tunnel and circulating in a spiral path through the trucks and the side compartments to an outlet duct 35 connected to the chamber 32. The moisture-laden gases are heated in the chamber and pass through the heating tubes 28 to an exhaust duct connected to a fan 37.

Title: Improvements in and relating to construction of thermal conductivity cells for use in gas analysis apparatus
IPC: G01N27/18
Filed: 1931-10-21
Abstract: In gas analysis apparatus of the thermal conductivity type, the thermal resistance elements in a Wheatstone bridge consist of electric incandescent lamps or the filaments of thermionic valves, as shown in Fig. 4.  A suitable thermal conductivity cell, shown in section in Fig. 3, consists of a standard pipe Tee, having an electric incandescent lamp 6 held by cement 7 in the transverse portion 5 of the Tee, the bulb extending into the longitudinal portion 4.  Apertures 8 are provided in the bulb for the gases. Two of these cells may be strapped together and inserted in a Wheatstone bridge.  The gases are passed through one cell, then through a scrubbing device which removes gases from the mixture and then through the second cell.  The difference between the resistances of the two cells gives a measure of the <PICT:0380278/III/1> <PICT:0380278/III/2> gases absorbed.  The bulbs may be opened, as shown above, or left closed, and may be of the vacuum or gas-filled type.  The filaments may be made of tungsten, tantalum, their alloys, platinum or nickel, but if they are to be exposed to the gases, a non-corrodible material is preferable.  The lamps, especially if gas-filled, may be inserted directly in the bridge circuit as a reference cell, the other lamps being provided with apertures for the passage of the gases.  Alternatively the filaments may be removed and inserted in suitable chambered blocks of heat conducting material. The Specification as open to inspection under Sect. 91 (3) (a) states that the device may be used as a flow meter.  This subject-matter is not included in the Specification as accepted.

Additional tubes parallel to the reaction tubes and extending lower into the chamber 9 may be provided for circulation of the liquid.  The chamber 9 may be divided into compartments each having a separate gas inlet; by varying the number of inlets used, the size of the gas bubbles and the residence time of the gas in the apparatus are regulated. Baffles 11, 12 control the path of the heat exchange medium in the shell 4.  The gas distributing means may consist of serrations in the lower ends of the reaction tubes or porous rings or plugs; various forms are illustrated (Figs. 4-9, not shown).  The apparatus may be used for halogenation, hydrogenation, oxidation, hydroformylation, alkylation, and polymerization; specific examples are the reaction between propylene, carbon monoxide, and hydrogen with a cobalt carbonyl catalyst to make butyraldehydes, oxidation with air or oxygen of liquid hydrocarbons to make fatty acids, and air blowing of vegetable oils.
