VERFAHREN ZUR HERSTELLUNG VON AKTIVKOHLE

摘要

1. A method for manufacturing activated carbon from preferably forest-fresh chopped material, with or without binder as the case may be compressed ligno-cellulose material - such as for example peat -, sawdust pallets, and their carbonised products in a continuous process in a shaft furnace employing a combustion chamber, characterised in that a hot water vapor-containing gas having at most 0.5 volume % oxygen and about 1 volume % carbon monoxide and a temperature lying around 10 to 30 degrees C above the temperature in the activation zone is manufactured in the combustion chamber by combustion of at least a portion of the exhaust gas, and is introduced at the level beneath the activation zone at a speed of 0.1 to 0.6 metres per second (with respect to the empty furnace).
