Abstract
500,642. Purifying liquids; humincontaining substances. UNITED WATER SOFTENERS, Ltd. 'May 6, 1937, Nos. 12983 and 12984. Void. Convention dates, May 7, 1936 and May 7, 1936. [Class 46] [Also in Group IV] The . base-exchange capacity of natural or artificial humic materials is increased by subjecting the materials to the action of hot water or steam. Peat, lignite, or coal may be treated either in the natural state or after chemical treatment, for example with acid or with dehydrating and oxidizing agents. The material is granulated and preferably moistened and a stream of boiling water or steam, which may be under pressure, is passed through it. The treatment is more effective if carried out in the presence of an electrolyte. Suitable alkaline electrolytes are caustic soda potash, ammonia, lime, baryta, and alkali carbonates and bicarbonates. Neutral electrolytes such as sodium chloride, sodium sulphate, and calcium chloride, may be used; also acid electrolytes such as hydrochloric sulphuric or phosphoric acid. The material may be moistened with a solution of the electrolyte. The material may be subjected to a final dry heat treatment in vacuo at a temperature of 50 to 350‹ C.
