简介 Catalyst compositions for use in oxychlorination reactions, in particular the oxychlorination of ethylene, are disclosed. The catalyst compositions are in the form of particles suitable for use in fluid bed reactors, in particular baffled fluid bed reactors. Compared to prior art oxychlorination catalyst materials the catalyst particles disclosed herein have a reduced tendency to stick together under oxychlorination reaction conditions. Preferred catalyst materials comprise from 5.5 wt % to 14 wt % Cu. They may further comprise an earth alkali metal, such as Mg, and/or a rare earth metal. Preferred compositions contain less than 1 wt % of an alkali metal, which preferably is K
