Abstract

213,939. Algemeene Norit Maatschappij, (Assignees of Sauer, J. N. A.). May 26, 1922, [Convention date]. Carbon and charcoal.-Granular activated carbon, which has absorbed organic matter, is revivified by being subjected to the action of heat and activating gases while being mechanically agitated, the organic matter being thereby carbonized and removed. The heating of the drum or chamber used for regeneration may be internal, such as by injection of hot or burning gas, external, or both. Gases such as chlorine and sulphur dioxide may be used to remove inorganic impurities. The Specification as open to inspection under Sect. 91 (3) (a) describes a process in which the action of the gases is limited to the carbonization of the organic matter and the activation but not complete consumption of this secondary carbon. This subject-matter does not appear in the Specification as accepted.
