IPC: C01B17/92
Filed: 1926-08-25
Abstract: 258,241. Demann, W. Sept. 9, 1925, [Convention date]. Mineral and tar oils, purifying.-Acid, and in some cases resin, is recovered from the acid sludge obtained in the refining of benzole by stirring with water and a heavy benzine, heavy benzole, or " Tetralin " or like substances of a strongly aliphatic or polymethylene character, and centrifuging to separate the coagulated resins. In an example the sludge is diluted with 30 per cent of water, cooled if necessary, and 30-50 per cent of heavy benzine, heavy benzole, or " Tetralin " added. The resins form a single lump from which the acid and benzine are decanted. The resin is freed from acid by pressing or centrifuging, and then grinding with gas liquor, ammonia solution, caustic soda, or other alkali. The solid resins are dried and ground; the liquid resins are dissolved in turpentine, alcohol, or other suitable vehicle to form slowly drying hard lacquers. The prior treatment with benzine and water of resins obtained when refining petroleum with sulphuric acid is referred to. The Specification as open to inspection under Sect. 91( 3) (a) describes also the treatment of acid sludges from the refining of oils generally by (1) the above processes; or (2) bleaching earths or other adsorbents, e.g. fuller's earth, silica gel, and animal charcoal; or (3) substances which themselves coagulate or resinify therein, e.g. phenol, sodium phenate, formaldehyde, and alkali silicates, whereby the resins and other impurities are adsorbed or coagulated. Treatment by any other method may precede or follow. This subject-matter does not appear in the Specification as accepted.
