Abstract

315,546. Leny, W. d' and Imperial Chemical Industries, Ltd. June 13, 1928. Carbon.-Active carbon which has been used for absorbing sulphur compounds from gases is regenerated by treatment with aqueous nitric acid, e.g. of about 15 per cent strength, so as to oxidize the sulphur or sulphur compounds. The acid may in some cases be heated, e.g. to about 50‹ C., to accelerate the reaction.. The wash liquor may be used repeatedly, if necessary with the addition of fresh nitric acid, until it becomes too rich in sulphuric acid, when it is distilled to recover the nitric acid. The carbon may finally be washed with distilled water,
