Abstract

See full text

An improved hydrotreating catalyst and process for making a base oil product. The catalyst comprises a base extrudate of a high nanopore volume amorphous silica alumina (ASA) and alumina. The catalyst and process use a high nanopore volume ASA/alumina based catalyst to produce hydrotreated dewaxed base oil products from a hydrocarbon feedstock. The base extrudate comprises ASA having a pore volume in the 11-20 nm pore diameter range of 0.2 to 0.9 cc/g and an alumina having a pore volume in the 11-20 nm pore diameter range of 0.01 to 1.0 cc/g. The base extrudate formed has a total pore volume in the 2-50 nm pore diameter range of 0.12 to 1.80 cc/g. The catalyst further comprises at least one modifier element from Groups 6 to 10 and Group 14 of the Periodic Table. The catalyst and process provide improved aromatics saturation.
