METHOD FOR PREPARING CARBON FUEL FOR SMOKING ARTICLES

摘要

The invention is directed to a method for producing carbon containing fuel elements for smoking articles and to such a fuel element prepared by such method. …In order to obtain a pure fuel element a carbon containing starting material is pyrolyzed at a temperature range between about 400 DEG C and 1250 DEG C in a non-oxidizing atmosphere, the pyrolyzed material is then cooled in a non-oxidizing atmosphere, whereupon the size of the pyrolyzed material is reduced and then the pyrolyzed material is reheated in a non-oxidizing atmosphere at a temperature of at least 650 DEG C for a period sufficient to remove volatiles therefrom.
