Patent number: 7704379Abstract: The present invention relates to a process for converting Fischer-Tropsch wax to high quality lube basestocks using a molecular sieve Beta catalyst followed by a unidimensional intermediate pore molecular sieve with near circular pore structures having an average diameter of 0.50 nm to 0.65 nm wherein the difference between the maximum diameter and the minimum is ?0.05 nm. Both catalysts comprise one or more Group VIII metals. For example, a cascaded two-bed catalyst system consisting of a first bed Pt/Beta catalyst followed by a second bed Pt/ZSM-48 catalyst is highly selective for wax isomerization and lube hydrodewaxing with minimal gas formation.Type: GrantFiled: October 8, 2002Date of Patent: April 27, 2010Assignee: ExxonMobil Research and Engineering CompanyInventors: Zhaozhong Jiang, Terry Eugene Helton, Randall David Partridge, Larry E.
