A study on c-Al 2 O 3 supported CuCl 2 /KCl/LaCl 3 for ethane oxychlorination was carried out by means of XRD, XPS,TGA/ DTA, BET TEM and ICP. The experimental results indicate that the catalytic properties of the 5 wt,%Cu-6 wt.%K-5 wt.%La/ c-A1 2 O 3 are optimal. This catalyst was studied in more detail and it was found that deactivation of the catalyst was due to carbon deposition and loss of active species of Cu +2 .

Effect of KCl on the structure and the catalytic properties of CuCl 2 /γ-Al 2 O 3 catalyst for ethane oxychlorination has been studied by means of solubility test, UV-vis spectroscopy, XRD, TPR, TEM and catalytic reaction. Addition of KCl decreases the interaction between active species CuCl 2 and γ-Al 2 O 3 and increases the catalytic properties by accelerating the Cu(II) → Cu(I) reduction step.
