Beschreibung
Zusammenfassung:	A method is described for rendering total liquid product hydroisomerates daylight stable and improving their oxidation stability, which method involves treating the hydroisomerate total liquid product (6) with a Group VIII metal on refractory metal oxide catalyst or Group VIII metal on halogenated refractory metal oxide catalyst under mild conditions (7), which conditions are a temperature in the range of 170 to 270 DEG C, a pressure in the range of 300 to 1500 psi (3.4 to 6.9 MPa) H2, 0.25 to 10 v/v/hr and 500 to 10,000 SCF/B (178 to 890 liters H2/liter oil) H2.
