Abstract

A process for the production of high-quality activated car­ bons from carbonized, self-regenerating, carbon-containing biomasses selects the carbonized biomasses from HTC car­ bon 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 activa­ tor 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.
