| Zusammenfassung: | The invention refers to processes for activated coal obtaining from carboniferous raw material, which may be used in the process for purification of surface and underground waters, in the food industry for liquid purification, as well as in medicine for detoxication of the human organism. The process, according to the invention, includes carbonization of the degreased grapestones at the temperature of 400...500 degree C during 0,5...2,0 hours and activation thereof with water vapors at the temperature of 850... 1050 degree C during 1,5...3,0 hours.The result of the invention consists in increasing the adsorptive capacity of the activated coal.Claims: 1 |
