A process is disclosed for the catalytic oxychlorination of an olefin. In the process a feed containing the olefin, O2 and HCl is contacted with an oxychlorination catalyst. The O2/2HCl ratio in the feed is in the range of from 0.50 to 0.58. Catalyst compositions for use in the oxychlorination reaction, in particular the oxychlorination of ethylene, are also disclosed. The catalyst compositions are in the form of particles suitable for use in fluid bed reactors, in particular baffled fluid bed reactors. 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.
