Abstract (en)

[origin: EP0155822A2] Waxy oil, either a lubricating oil base stock or a fuel oil, is catalytically dewaxed using a catalyst comprising ZSM-11. The ZSM-11 may contain hydrogenation/dehydrogenation component such as Pt or Ni Mo. Dewaxing proceeds by wax cracking and wax isomerization.
