ABSTRACT:
A fluidizable catalyst composition is provided having cupric chloride deposited on a fluidizable, modified gamma alumina support in which the support has incorporated, prior to the deposit of copper, from 0.5% to 3.0% by weight based on the weight of the support of at least one metal selected from the group consisting of potassium, lithium, rubidium, cesium, alkaline earth metals, rare earth metals, or combinations thereof. Such catalyst compositions are extremely useful as the fluid bed catalyst in the vapor phase oxyhydrochlorination reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichloroethane. The use of the catalysts results in improved EDC efficiency based on ethylene and avoids operating problems caused by stickiness of the catalyst in the fluid bed. Incorporation of a combination of potassium and barium in the fluidizable gamma alumina support, prior to deposit of the copper, produces an excellent catalyst for a fluid bed ethylene oxyhydrochlorination process in which the vent gases from the process are recycled.
