| Abstract: | Conclusions Reasons for the self-ignition of activated carbons have been ascertained, based on an analysis of the mineral portion of such carbons.It has been found that the self-ignition temperature of industrial types of activated carbon depends on their alkali metal content.It has been shown that heating up of granules of activated carbon takes place as a result of an exothermic oxidation of carbon to carbon dioxide.Cases of self-ignition of activated carbons in the recovery of carbon disulfide from exhaust air from viscose plants are explained by an impregnation of individual, usually overdried, dusty regions with alkali metal salts.Translated from Khimicheskie Volokna, No. 6, pp. 11–12, November–December, 1984. |
