PROCESS FOR THE PRODUCTION OF HIGH-QUALITY ACTIVATED CARBONS AS WELL AS ACTIVATED CARBONS PRODUCED ACCORDING TO THE PROCESS

摘要

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.

1. A process for producing activated carbons from carbonized, self-generating carbon-containing biomasses comprising:
(a) selecting the biomasses from hydrothermal carbonized (HTC) carbon from fruit stores or hydrothermal carbonized (HTC) carbon from nut shells; and (b) subjecting the biomasses together with potassium hydroxide, sodium hydroxide, or a mixture of potassium hydroxide and sodium hydroxide as activator to a heat treatment at temperatures where the activator exists in a form of a melt; wherein the activator and the biomasses are present in a weight ratio of 0.5:1 to 6:1 at commencement of the heat treatment.
