Abstract
This invention relates to an efficient process for shape-selective conversion of organic feedstock with a catalyst comprising a Clathrate Group tectosilicate such as ZSM-39 and a highly siliceous, shape selective zeolite such as ZSM-5. In one embodiment, a stabilized, dewaxed lube stock is prepared by catalytically dewaxing a hydrocrackate.
