ABSTRACT:
An improved process for catalytically dewaxing a hydrocarbon oil is disclosed. In this process the waxy oil is contacted in the presence of hydrogen with a dense zeolitic dewaxing catalyst associated with a nickel-tungsten hydrogenation component. The dewaxed oil has unexpectedly good stability and a low bromine number compared with prior-art processed oils. The process may be used to dewax crude oils, fuel oil fractions and lubricating oils.
