Abstract :
The effect of exposure to C2H4 of different CuCl2/Al2O3 catalysts characterized by a wide copper content (0.25Al–OH groups; and (ii) >Al3+ coordinative unsaturated Lewis acidic sites are present on the catalyst. These results point out the possible determinant role of the support in side reactions and coking that are responsible for loss of selectivity and, respectively, catalyst decay during industrial runs.
