Thermally activated Cellulose based Carbon and Thermal Stabilization process of the Coal

摘要

The activated cellulosic base carbon is made more thermally stable by exposure to water or aqueous acid, and optionally, to a halogen and / or a halogen-containing compound. Such treated cellulosic base carbon improves thermal properties and is suitable for reducing the content of toxic substances in gas flushing, especially the flue gas having a temperature within the range of about 100 ° C to about 420 ° C.
