310 Dry decomposition of PFC14 with solid alkali reactant

Abstract

An effective decomposition method for perfluorocarbon-14 (PFC14 ; CF_4) which is known as a global warming substance, has been developed. Successfully, this method decomposed PFC14 under dry conditions using a solid alkali and γ-alumina, and any liquid waste treatment was not required for outlet gas treatment as an expecting feature. We found that fluorocarbon-14 was decomposed quite enough, and the experimental result could be satisfied with the national criterion. The decomposition temperature was lower than that with the typical combustion system applied for almost all perfluorocarbons except for PFC14.
