Abstract:
1. In an oxychlorination process where ethylene is converted to 1,2-dichloroethane in the presence of a supported copper catalyst, the improvement comprising: the use of a supported catalyst prepared by (i) impregnating, within a first step, an alumina support with a first aqueous solution including copper, optionally an alkaline earth metal, and an alkali metal to thereby form a first catalyst component; and (ii) impregnating, within a subsequent step, the first catalyst component with a second aqueous solution including copper and alkaline earth metal to thereby provide the first catalyst component with additional copper and additional alkaline earth metal, where the second aqueous solution is substantially devoid of alkali metal, and where the amount of additional alkaline earth metal is greater than 0.07 moles of alkaline earth metal based upon the total weight of the supported catalyst to thereby form the supported catalyst, where the supported catalyst includes from about 5.0 to about 12 weight percent copper.
