  • PROCESS FOR THE PRODUCTION OF HIGH-QUALITY ACTIVATED CARBONS AS WELL AS ACTIVATED CARBONS PRODUCED ACCORDING TO THE PROCESS
    Publication number: 20170007980
    Abstract: A process for the production of high-quality activated carbons from carbonized, self-regenerating, carbon-containing biomasses selects the carbonized biomasses from HTC carbon from fruit stones and HTC carbon from nut shells. The carbonized biomasses together with potassium hydroxide, sodium hydroxide or a mixture of both hydroxides as activator are subjected to a heat treatment at temperatures at which the activator exists in the form of a melt. The activator and the carbonized biomasses are present in a weight ratio of 0.5:1 to 6:1 at the beginning of the heat treatment.
    Type: Application
