Process to prepare a heavy and a light lubricating base oil |
摘要 |
The invention relates to a process to prepare a heavy and a light lubricating base oil from a partly isomerized Fischer-Tropsch derived feedstock, the feedstock having an initial boiling point of below 400° C. and a final boiling point of above 600° C. by (a) separating the fraction via distillation into a light base oil precursor fraction and a heavy base oil precursor fraction; (b) reducing the pour point of each separate base oil precursor fraction via dewaxing; and, (c) isolating the desired base oil products from the dewaxed oil fractions as obtained in step (b).
