Patent GB-189920925-A (GB)
Title: A Process for Directly Obtaining the Caustic Lyes and Ammonia and Earth Alkaline Hydroxides by Electrolysis.
Inventor: LUCKOW CARL
Filed: 1899-10-19
Granted: 1900-10-19
Abstract: 20,925. Luckow, C. Oct. 19. Hydrogen, obtaining electrolytically. The electrolytic tank consists of a lower vessel a of stoneware, and an upper one b of iron. These are connected together by an india-rubber packing- washer d and a metal ring d<4>. The lower part receives a band of a heavy metal, such as lead, copper, silver, zinc, or iron, or an alloy, wound to form a spiral g which rests upon a paraffined wooden crose-piece f of triangular crosssection. The spiral is connected by a metal band h to the positive conductor. This band passes through the charging-tube c for the electrolyte. Within the upper part b is placed the cathode i, consisting of open wirework of any suitable metal or alloy, also wound to form a spiral, and supported by crossed conductors k, which connect it to the negative lead k<1>. Above the anode is a filter of porous cloth d'. The electrolytes are solutions of the salts of the alkaline metals, including ammonium, and of the alkaline-earth metals, except calcium, as simple or double salts, or as mixtures, or as compounds with other matter, such as natural salts, or mixed waste products of manufactories of almost any kind. The electrolytes are more or less concentrated, and more or less heated. Any insoluble impurities in the electrolyte are stopped by the filter d', and slowly fall down. When the current passes, the acid liberated at the anode attacks the latter, forming a more or less insoluble salt, which slowly descends as a powder or as flakes through an iron tube p to a collecting-barrel s, finally resting upon the filtering-fabric s<2> covering the perforated false bottom s'. The alkaline or other metal liberated at the cathode immediately combines to form the hydrate. When the solution is sufficiently strong, it is allowed to flow off through a tube e, e<2> e3 to an evaporator w, fresh electrolyte being fed in through the tube c to keep the level constant. Hydrogen and, in some cases, ammonia are also liberated, and are collected by a dome l, and led to stoneware absorbers l<l>, l<2>, for collecting the ammonia as salts, while allowing the hydrogen to pass to a holder. The current employed is preferably about 10 amperes per square metre of cathode surface, or 20 to 50 ampÞres per square metre of anode surface.
