    摘要: There is disclosed a method and composition for improving the fluidization characteristics and alleviating or inhibiting stickiness in a supported cupric chloride catalyst used as fluid bed catalyst in oxyhydrochlorinations reactions. The method involves the in situ preparation of the supported cupric chloride catalyst by addition of bare support on which no cupric chloride is deposited to the supported cupric chloride catalyst in the fluidized bed, or the use in the bed as the initial charge or as addition to the bed as makeup, of a composition which is a mixture of supported cupric chloride catalyst and bare support. In either event, as the oxyhydrochlorination proceeds, a portion of the cupric chloride on the supported catalyst becomes released therefrom and deposited in situ on the bare support, and stickiness of the cupric chloride containing catalyst particles to one another in the fluid bed is alleviated or inhibited.

    摘要: 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 1.0% 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 1:1. 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.

    摘要: 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.
