| 20080214879 | Oxychlorination Catalyst and Process Using Such a Catalyst - Oxychlorination catalyst containing at least copper as an active element deposited on a support characterized in that the support consists essentially of an alumina obtained by calcination of an alumina hydrate obtained as by-product of the ALFOL® linear primary alcohol process and use of such catalyst in an oxychlorination process of a hydrocarbon containing 1 to 4 carbon atoms. | 09-04-2008 |
| 20100274061 | OXYCHLORINATION CATALYST - Process for the oxychlorination of ethylene to form 1,2-dichloroethane in the gas recycle mode with reduced accumulation of hydrogen, which comprises the following steps:

| 20110178345 | METHOD FOR UTILIZATION OF THE REACTION HEAT THAT OCCURS IN THE PRODUCTION PROCESS OF 1,2-DICHLOROETHANE FROM ETHYLENE IN A FLUIDIZED BED REACTOR - With a method for utilization of the reaction heat that occurs in the production of 1,2-dichloroethane from ethylene, by reaction with oxygen and hydrochloride (oxychlorination), in a fluidized bed reactor, with dissipation of this reaction heat through cooling pipe bundles situated within the reactor, positioned in the fluidized bed, utilization of the heat is supposed to be improved, while simultaneously reducing the size of the corresponding system elements. This is achieved in that part of the reaction heat is dissipated by heating boiler feed water, whereby the heated boiler feed water is used to heat heat sinks in the production process. | 07-21-2011 |
| 20140128643 | CATALYST FOR THE OXYCHLORINATION OF ETHYLENE TO 1, 2-DICHLOROETHANE - This invention relates to a catalyst containing from about 2 up to about 8% by wt. of copper, zero up to about 0.6 moles/kg of one or more alkali metal(s), from about 0.08 up about 0.85 moles/kg of one or more alkaline earth metals and from about 0.09 up to about 0.9 moles/kg of one or more transition metals selected from the group consisting of Mn, Re and mixtures thereof, where all the metals are impregnated in form of their chlorides or other water soluble salts on a fluidizable support with a BET surface area of from about 80 up to about 220 m | 05-08-2014 |
| 20140275661 | CATALYST AND PROCESS FOR OXYCHLORINATION OF ETHYLENE TO DICHLOROETHANE - In an oxychlorination process of the type 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, 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, where the second aqueous solution is substantially devoid of alkali metal, to thereby form the supported catalyst. | 09-18-2014 |
