Abstract:
1. A process for converting a Fischer-Tropsch wax having at least about 95% n-paraffins to an isoparaffinic lube basestock, consisting of: first, passing the Fischer-Tropsch wax and a hydrogen co-feed over a first catalyst selected from the group consisting of a Beta catalyst consisting of a Zeolite Beta and one or more Group VIII metals, to form an intermediate product; and second, passing the intermediate product over a second catalyst selected from the group consisting of a unidimensional molecular sieve catalyst consisting of a ZSM-48 unidimensional intermediate pore molecular sieve and one or more Group VIII metals; to form the isoparaffinic lube basestock in a yield which is about 10% higher at a given pour point than that obtained using the unidimensional molecular sieve alone or obtained using the unidimensional molecular sieve catalyst first and the Beta catalyst second.
