초록

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.

청구항

[ We claim:] [1.] A process for catalytically dehazing a lubricating base oil, which process comprises contacting a dewaxed lubricating base oil in the presence of hydrogen with a catalyst comprising naturally occurring ferrierite or a synthetic ferrierite or a combination of a natural and synthetic ferrierite, which ferrierite is modified to reduce the mole percentage of alumina, and a low acidity refractory oxide binder material which is essentially free of alumina.
