FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of activated carbon based on nut shells and kernels, which can be used for purification of drinking water, as well as various liquids and solutions. Disclosed is a method for production of crushed active coal, including carbonisation, crushing carbonated coal, sieving of its grains, activation with steam and cooling. Carbonisation is carried out at a rate of raising temperature 3–8 °C/min to final temperature of 450–550 °C. Activation is carried out at temperature of 820–850 °C to burnt product 30–45 wt%.
EFFECT: disclosed method enables to obtain crushed active coal with high adsorption capacity during extraction of chloroform and chlorophenols from water.
