Abstract: A fluidizable catalyst composition is provided containing about 2% to about 8% by weight of copper (about 4% to about 17% by weight of copper salt), from about 0.2% to about 10% by weight of a rare earth metal salt(s), preferably the chloride salt(s), and from about 0.25% to about 2.3% by weight of an alkali metal salt(s), preferably the chloride salt(s), all weight percents based upon the total weight of the catalyst composition. The metals are codeposited on a fluidizable, high surface area alumina support. The weight of the alkali metal employed is not over 2.5% by weight (as the chloride) and the weight ratio of the rare earth metal salt(s) to the alkali metal salt(s) must be at least 0.8:1. Such catalyst compositions are extremely useful as fluid bed catalysts in the vapor phase oxychlorination reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichloroethane (EDC). The use of the catalysts results in improved, high percent ethylene efficiencies and high percent HCl conversions, and avoids operating problems caused by stickiness of the catalyst in the fluid bed. A combination of copper chloride, potassium chloride and one or more of the rare earth chlorides on a fluidizable gamma alumina support, produces an excellent catalyst for a fluid bed ethylene oxychlorination process.
