Impregnated chloride ions are removed from a chloride containing, platinum on zinc aluminate catalyst support in a specific sequence of operations. In the dechlorination steps, the impregnated platinum is first anchored to the zinc aluminate support in a calcining step, and then the calcined catalyst support is washed with a wash medium to remove the corrosive chloride without removing the platinum catalyst.

Description d'une séquence spécifique d'opérations pour enlever les ions chlorure d'un support de catalyseur à base d'aluminate de platine ou de zinc contenant du chlorure. Pendant la déchloration, le platine imprégné est d'abord ancré au support d'aluminate de zinc au cours d'une étape de calcination, puis le support de catalyseur calciné est lavé avec un milieu de lavage pour éliminer le chlorure corrosif sans enlever le catalyseur à base de platine.
