Abstract
206,862. Algemeene Norit Maatschappij, (Assignees of Sauer, J. N. A.). May 26, 1922, [Convention date]. Charcoal.-A process for producing uniformly active charcoal of the type in which a carbonaceous material is distilled in presence of active gases is characterized in that the raw material, which may be coal, brown coal, or coke produced by the low temperature carbonization of dense peat &c., is first pulverized or granulated preferably uniformly and then subjected to the action of heat and activating gases while being maintained in a state of agitation and suspension by a blast of gas. The raw material may be preliminarily carbonized at for example above 800‹ C., the products of distillation being quickly swept away, such as by the passage of practically inert gases. The activating gases specified are steam, preferably superheated, carbon dioxide, air, oxygen, hot burning gases and gases cf combustion, carbon monoxide, hydrogen, generator gases and oxidizing gases. Chlorine and sulphur dioxide may be used to remove inorganic impurities. A hori- or vertical retort may be employed. In an example the process is applied to charcoal granules the heating of the retort being internal, external or both. A series of retorts or of zones may be employed, in which there are introduced different activating gases and in which are maintained different temperatures. The Specification as open to inspection under Sect. 91 (3) (a), describes also the application of the process to the regeneration of spent charcoal, the action of the gases being limited to the secondary carbon. The vertical retort described in Specification 189,148 is referred to as a suitable apparatus. Anthracite and the less porous kinds of coal are also specified as raw materials. This subject-matter does not appear in the Specification as accepted.
