Abstract
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.
