Abstract

302,774. Metallbank und Metallurgische Ges. Akt.-Ges. Nov. 1, 1927. Addition to 238,889. Carbon. - Active carbon of high absorptive power and mechanical strength is obtained by heating fine-pore vegetable materials, such as plum stones, cocoanut shells, and other hard shells, which are broken up into small pieces, with a concentrated solution of zinc chloride, the weight of zinc chloride employed being less than that of the vegetable material treated. In an example, 100 kilograms of plum stones which have been broken and the kernels removed are treated with a concentrated liquor at 100‹ C., containing 70 kilograms of zinc chloride. The mixture is dried at about 200‹ C., and then heated to 700‹C. The zinc chloride is extracted with hydrochloric acid and water from the carbonized residue which is next dried, broken up and sieved.
