Abstract
A process for catalytically dehazing lubricating base oils is disclosed, which comprises contacting the lubricating base oil in the presence of hydrogen with a catalyst comprising naturally occurring and/or synthetic ferrierite which ferrierite has been modified to reduce the mole percentage of alumina and a low acidity refractory oxide binder material which is essentially free of alumina.
