Abstract

247,241. Sauer, J. N. A. Aug. 13, 1924. Purifying liquids.-Particles of active carbon are coated or impregnated with a supplementary active carbon or an inorganic adsorbent material. The latter may act as binders, when hard agglomerates may be obtained with or without the use of pressure. The supplementary active carbon is produced by impregnating the base of active carbon with a carbonizable solution, carbonizing and finally activating by means of gas or other known chemical activating agents, while the supplementary inorganic adsorbent is produced by precipitation in situ within the pores of the active carbon base, followed by careful drying and heating. To prevent loss of absorbing power of the active carbon base, substances producing gases may be added; for example, prior to impregnation the base may be treated with benzol or other volatile liquid, or yeast or ammonium carbonate may be added. In an example an active carbon of low apparent specific gravity is treated with water-glass and hydrochloric acid is added so as to produce progressive gelatinization of silicic acid. On carefully drying and heating a hard product of increased specific gravity is obtained. In a second example an active carbon is mixed with sulphite-cellulose lye and lime or calcium carbonate and the mass carbonized and subsequently activated. Before carbonization the mass may be moulded and subjected to pressure whereby hard tablets, rods, granules &c. may be produced. Silica gel resulting from the hydrolysis of silicon chloride, oxides of aluminium and iron, insoluble or sparingly soluble salts of calcium, oxalates, phosphates, citrates and aluminates are mentioned as other suitable supplementary adsorbents when prepared under conditions producing a highly adsorbent product. Different inorganic adsorbents may be applied successively or simultaneously and the active carbon base and the supplementary adsorbent may possess complementary powers. The composite product is suitable for the treatment of liquids including the removal of colouring matter and other impurities. It may be regenerated by igniting or by treatment with steam or dry air. Specifications 213,939 and 213,940, [both in Class 90, Non-metallic elements], are referred to.
