Abstract

Active carbon is prepared by pulverizing particles of fly ash from the burning in air, at at least 1500 DEG F. of bark or "pine wood waste." The product has an iodine value of at least 75 and a phenol value of not greater than 30. "Pine wood waste" consists of the bark, cones, needles and some wood from small branches of pine trees. The fly ash may be activated by treating with air at 900-1000 DEG F., steam at 1400 DEG -1800 DEG F., carbon dioxide at 1400 DEG -1800 DEG F. or mixtures of steam, air and carbon dioxide at 1400-1800 DEG C. The product is used to remove undesirable taste, odour and colour from liquids e.g. water.
