I disclose a single stage, multilayered catalyst system capable of hydrodehazing and hydrofinishing a solvent dewaxed lube oil base stock. In the first layer, I catalytically dewax the solvent dewaxed stock. In the second layer, I hydrofinish the catalytically dewaxed stock. My invention also relates to a process for hydrodewaxing and hydrofinishing a solvent dewaxed lube oil base stock. |
