摘要： The subject invention relates to catalyst compositions for oxychlorination of ethylene to produce 1,2-dichloroethane. The catalysts comprise copper chloride, at least one alkali metal, at least one rare earth metal, and at least one Group IIA metal on a high surface area support for fluid bed applications or on a high or low surface area support for fixed bed applications. The catalyst compositions are prepared by depositing the metals on a support. The use of the catalyst compositions of the invention in the oxychlorination of ethylene to EDC results in high percent ethylene efficiency, high EDC product purity and high percent HCl conversion without exhibiting catalyst stickiness. A process for oxychlorination of ethylene to produce 1,2-dichloroethane is also disclosed. The process relies on contacting a mixture of ethylene, oxygen or oxygen containing gas and hydrogen chloride with a fixed or fluidized catalyst composition in a reaction zone and recovering 1,2-dichloroethane from the effluents of the reaction zone.

摘要： The present invention relates to the recovery of alcohols, in particular ethanol, from a crude ethanol product obtained from the hydrogenation of acetic acid using a reduced energy process. The crude ethanol product may be fed to a distillation column in which a substantial portion of the water is removed with the acetic acid in the residue. Additional water may be removed by using a pressure swing adsorption unit, molecular sieve, and/or membrane. Ethanol extraction may also be used to reduce the ethanol concentration in the recycle streams.
