A supported catalyst for the C<sub>2</sub>H<sub>4</sub> oxychlorination within a fluidized bed, comprising a Cu compound in amounts corresponding to a content from 1 to 10% by weight -as Cu metal- on a carrier preferably selected from the group consisting of microspheroidal Al<sub>2</sub>O<sub>3</sub>, microspheroidal SiO<sub>2</sub> and microspheroidal silica-alumina, characterized in that the molar ratio (outer Me/outer Cu), as determined by means of XPS analysis, is at least 40% higher than the molar ratio:wherein Me is e.g. Al, Si or AI + Si. |
