    摘要: A method for reactivating the catalyst used in the mild hydrotreating of petroleum crude scale wax comprises contacting the catalyst with the feedstream at a temperature in excess of the normal operating temperature for the particular feedstream for a time sufficient to reactivate the catalyst and produce effluent having satisfactory color and stability characteristics. Operation at a temperature in excess of the normal operating temperature may follow conventional air-stream catalyst regeneration.
