Abstract
A supported catalyst for the C.sub.2 H.sub.4 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 O.sub.3, microspheroidal SiO.sub.2 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: ##EQU1## wherein Me is e.g., Al, Si or Al +Si. The invention concerns a supported catalyst for the synthesis of 1,2-dichloroethane, hereinafter DCE, achieved by ethylene oxychlorination, said catalyst being used in the form of a fluidized bed.
