A study on gamma-Al2O3 supported CuCl2/KCl/LaCl3 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/ gamma-Al2O3 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.
