Abstract
A process is provided for upgrading an oligomerization product through hydrogenation and isomerization with some selective/minor cracking resulting in a synthetic lube base oil with improved pour point and viscosity index. The upgrading process includes contacting the oligomerization product with a hydrogenation catalyst and an isomerization catalyst under conversion conditions, which include the presence of hydrogen and a temperature sufficient to promote hydrogenation and isomerization with some selective/minor cracking. The hydrogenation catalyst contains a porous carrier material and a group VIII metal while the isomerization catalyst contains an aluminosilicate zeolite.
