Abstract

Ash-free carbon is obtained from purified lignin by carbonizing it by a wet method either before treatment with an alkali or after treatment first with an acid and then with an alkali. The lignin may be precipitated from waste cellulose lye by an acid, preferably hydrochloric acid, or produced from cellulosic material from which colophony may be removed by turpentine, the lignin being then washed with warm water. In an example, purified lignin is carbonized by heating with sulphuric acid of 65 DEG Baum<\>ae for about 12 hours at 165-200 DEG C. After removal of excess sulphuric acid, the mass is treated with a solution containing 4 parts of sodium carbonate and 1 of potassium carbonate until the silicates are removed, washed with warm water, treated with concentrated hydrochloric acid for 8-12 hours and then washed with warm water. In a second example, treatment with gaseous hydrofluoric acid and caustic soda is carried out prior to carbonization with hydrochloric acid. After washing and drying the carbon is ground, further treated with sulphuric acid, washed and dried. The Specification as open to inspection under Sect. 91 (3) (a) states also that the carbonization of the lignin may be effected by dry distillation. This subject-matter does not appear in the Specification as accepted.
