Improved method of low temperature performance base oils using a combination catalyst system

摘要

Metal hydride on a support containing isomerization second component is an amorphous inorganic oxide and dewaxing a first component selected from a mixture thereof (57) as well as 12-ring molecular sieve and [Abstract] 10 membered ring is converted to a base oil feedstock using an integrated mixed powder pellet catalyst formed by a component. The first and second components are present in a ratio sufficient to promote the decomposition of naphthenic and isomerization of wax without causing a substantial reduction of the VI.
