A catalyst comprises a Theta-1, ZSM-22, ISI-1, NU-10 or KZ-2 zeolite, a ZBM-30 zeolite synthesized with a particular template, e.g. triethylene tetramine, a hydrogenation-dehydrogenation component and a porous mineral matrix. An independent claim is also included for improving the pour point of a paraffinic feed by contacting the feed with a dewaxing catalyst as above. |
