ABSTRACT:
A method is described for non-oxidatively reactivating coked dewaxing catalyst comprising a zeolite component such as ZSM-5 or zeolite beta. Use of a noble metal as a hydrogenation component associated with the zeolite component, preferably palladium, results in a catalyst which is readily reactivatable by contact with hydrogen at elevated temperatures.
