Abstract (en)
[origin: EP0219927A1] A process for obtaining a very high quality lube base stock is disclosed which comprises: (a) introducing an aromatic and nitrogen-and sulfur-containing feedstock selected from a dewaxed oil obtained from refining distillate fraction and having a 60 to 700 SUS at 38 DEG C (100 DEG F) and a dewaxed oil obtained from refining vacuum resid and having a 2300 to 2700 SUS at 38 DEG C (100 DEG F), and hydrogen, into a single stage hydrotreating reactor; and, (b) subjecting the feedstock to hydrotreating in the reactor in the presence of a sulfided cobalt/molybdenum hydrotreating catalyst at an average reactor temperature of from 288 DEG to 371 DEG C (550 to 700 DEG F) at a hydrogen partial pressure of 10340 to 20680 kPa.a (1500 to 3000 psia) at the reactor outlet, an LHSV of 0.1 to 1.0 and a hydrogen circulation rate of 53.4 to 445 vol/vol (300 to 2500 SCF per barrel). s
