| Abstract: | The manufacturing process of high decolorizing abilityactivated carbon from lignin in pulp and paper waste liquor was investi-gated.Results show that about 260 kg powdered activated carbon can bemade from one ton reed pulp and paper black liquor.Iodine number ofactivated carbon is more than 1000 mg/g.Methylene blue number of activa-ted carbon is more than 180 ml/g. Other quality indexes can meet the standardof LY216-79 proclaimed by the ministry of forestry. |
