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\xae linear primary alcohol process and use of such catalyst in an oxychlorination process of a hydrocarbon containing 1 to 4 carbon atoms. A network element securely provisions the device with a differential traffic control policy list that distinguishes how network traffic for at least one network type should be treated on a per-application basis. The layer system has a layer sequence of a metallic bonding layer, an inner ceramic layer and an outer ceramic layer, which are specially matched to one another.
