Abstract

The invention relates to the activated carbon preparation used for purification of drinking waters and sewage for decolorising in the food industry, as well as in the medicine during intoxication, stomach and kidney deseases, for enterosorption .The summary of the invention consists inthe fact that for active carbon preparation there is used agricultural waste material, which is carbonized by preheating to 400-600°C with further dry distillation, the prepared carbon is reduced to fragments and divided into fractions less than 0,25 mm, from 0,25 to 1 mm, from 1 to 2,5 mm, which are activated separately with water steam at 800-1100°C.The technical result of the invention consists in the increase of the active carbon total pores volume and its mechanical strength.Claims:1
