Abstract
Hydrotreating catalyst and process for making a base oil product using a catalyst having a base comprising a high nanopore volume amorphous silica alumina (ASA) and an alumina. The amorphous silica alumina has a pore volume in the 11-20 nm pore diameter range of 0.2 to 0.9 cc/g and the alumina has a pore volume in the 11-20 nm pore diameter range of 0.01 to 1.0 cc/g, with the base formed from the ASA and the alumina having a total pore volume in the 2-50 nm pore diameter range of 0.12 to 1.80 cc/g. The catalyst 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.
