The deactivation of Pd/C catalyst in the hydrodechlorination of the two chlorofluorocarbons CClF 2 –CF 3 (CFC-115) and CF 2 Cl 2 (CFC-12) into their corresponding hydrofluorocarbons CHF 2 –CF 3 (HFC-125) and CF 2 H 2 (HFC-32) has been systematically investigated. Besides Pd/C catalyst, Pd black was used as a model catalyst in order to...
Adsorption equilibria of chloropentafluoroethane (CF 3 CF 2 Cl, CFC-115) on Pd/activated carbon powder and on activated carbon powder were examined between 298.15 and 373.15K. The adsorption equilibria of CFC-115 on the Pd/activated carbon powder and the activated carbon powder can be well represented by the BET equation. The isosteric heats of adsorption of CFC-115 on both adsorbents...
The deactivation behavior of Pd catalysts on different supports in the hydrodechlorination of chloropentafluoroethane (CF 3 CF 2 Cl) was investigated. Changes of the BET surface area and the metal percentage exposed, measured by a multipurpose in situ catalyst characterization system during the reaction, gave some information about the deactivation mechanism of the Pd catalysts. The...
