Filed: 1920-07-09
Abstract: 148,239. Linck, K. Feb. 2, 1918, [Convention date]. No Patent granted (Sealing fee not paid). Charging.-A charging device for gas-producers comprises a hopper b having at its lower end a ring of cells c, beneath and above which respectively rotate an apertured plate e and a cover d both secured to a rotary shell f. The cover d is situated vertically above the aperture i, so that free passage of material from the hopper to the producer is prevented when the aperture registers with a cell c. Stirring-arms q, r within the hopper, and distributing-plates P, l<2> beneath the aperture i are provided. Gases from the producer may pass into the hopper through the space m and the opening n, and the products of distillation are drawn off through the outlet o. The Specification as open to inspection under Sect. 91 (3) (a) describes also a modification, in which the central shell f is fixed, and the plate e is formed in one with a lower rotary portion of the hopper. This subject-matter does not appear in the Specification as accepted.

Abstract: 779,387. Purifying gases. RUHRSTAHL AKT.-GES. July 14, 1955 [July 19, 1954], No. 20453/55. Class 55 (2). In a process for scrubbing CO 2  and/or H 2 S from gases containing them, the crude gas enters at 1 a first washing stage 2 wherein it is washed with an ammonium salt solution, e.g. ammonium carbonate, continuously circulated by a pump 3 through a cooler 4 so that the ammonium hydrogen salt is formed in the circulated solution, part of the circulating solution being continuously or intermittently withdrawn through line 5 for regeneration, and then passes into a second washing stage 7 wherein it is washed with an ammonium salt solution continuously circulated by a pump 8 through a cooler 9, ammonium hydroxide being added in this stage through line 10 preferably such that the concentration of free NH 3  in the solution circulating in this stage is below 1 per cent, finally the gases are washed with water in a third washing stage 11 to remove NH 3  and leave by outlet 13. Liquor withdrawn through 5 may be regenerated by the introduction of live steam into the liquor in known apparatus. The ammonium hydroxide thus obtained may be used to supply the ammonium hydroxide returned to the scrubber through line 10.

Patent GB-404983-A (GB)
Title: Improvements in the manufacture and production of acetic acid
IPC: C07C51/245
Filed: 1932-07-25
Abstract: Acetic acid is made by treating acetone or methylethyl ketone p  in the liquid phase with oxygen or a gas containing oxygen in the presence of an oxidation catalyst.  Suitable catalysts are metals having more than one valency and an atomic weight between about 50 and 200, e.g. vanadium, chromium, manganese, iron, cobalt, nickel, copper, molybdenum, cerium and other rare earth metals, tungsten, platinum, iridium, osmium and gold; the metals may be used as such or as oxides, carbonates, chlorides, sulphates, carboxylates such as formates, acetates, propionates, stearates, oleates, or tartrates, and enolates such as acetylacetonates; mixtures of catalysts may also be used, e.g. mixtures of cobalt and manganese acetates and/or acetylacetonates.  The reaction may be effected in the presence of a solvent; specified solvents are formic, acetic and propionic acids and their methyl and ethyl esters, and halogenated hydrocarbons such as carbon tetrachloride and chlorobenzene; acetic or formic acid is the preferred solvent; when another solvent or no solvent is used, a little acetic, formic or propionic acid is preferably added, to start the reaction.  The reaction temperature may be between 50 and 120 DEG C., and the pressure may be atmospheric or a raised pressure up to about 20 atm.  The reaction vessel may be made of ceramic material, glass, chrome-nickel steel, or nickel alloys free from iron, and may be packed with the same materials.  The used gas from the reaction vessel may contain a little acetaldehyde, which may be separated. The process may form a step in the manufacture of acetic acid from hydrocarbons such as propane, butane, ethane, propylene, butylene, and ethylene; thus, propane may be converted into acetone via propylene and isopropyl alcohol; butane may be converted into methylethyl ketone via butylene and secondary butyl alcohol; ethylene may be converted into butylene, as described in Specification 326,322, [Class 2 (iii), Dyes &c.], and then into methylethyl ketone as described above.  In the examples: (1) methylethyl ketone is treated with finely divided oxygen at 80--100 DEG  C. in the presence of acetic acid and manganese acetate; (2) oxygen containing vaporized methylethyl ketone is led into acetic acid containing manganese and copper acetates and heated to 100--103 DEG  C.; (3) oxygen containing acetone vapour is led into acetic acid containing manganese acetate and heated to 78--84 DEG  C.; (4) acetone is treated with air at 75 DEG  C. and 3--4 atm. pressure in the presence of acetic acid and cobalt and manganese acetylacetonates; acetic acid is produced in all the examples, and formic acid is also obtained in examples 3 and 4.

Scraper arms 20, 21 and 22 are provided to remove any accumulation of solidified slag. If necessary, an hydraulically-operated plunger device 23 may be provided to break up any thin bridge of slag. In a modification the water-cooled casing 16 is arranged with its narrower end downwards and the scraper arms are water-cooled and held by a rotary head in the centre of the discharge dish 19. The discharge dish may be arranged to rotate on a turn-table and gasefying agents may be supplied by a pipe in the vicinity of the scraper arms.
