DESTRUCTIVE ADSORPTION OF CARBON-TETRACHLORIDE ON IRON(III) OXIDE

The reaction between alpha-Fe2O3 and CCl4 has been studied in order to investigate the potential of iron oxide as a destructive reagent for chlorinated organic compounds. The reaction has been studied between 400 and 620-degrees-C in a fixed-bed pulse reactor. The effect of temperature, the contact time of the pulse of CCl4 with the alpha-Fe2O3, and the ratio of iron oxide to CCl4 have been investigated. The products have been analyzed (CO2, FeCl2 + FeCl3, Cl2, and small amounts of C2Cl4 and graphite; COCl2 is a short-lived intermediate), and a mechanism has been proposed for the decomposition of the CCl4 over the oxide.
