Process to prepare a lubricating base oil and a gas oil |
摘要 |
Disclosed herein is a process to prepare two or more lubricating base oil grades and a gas oil by (a) hydrocracking/hydroisomerisating a Fischer-Tropsch product, wherein weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms in the Fischer-Tropsch product is at least 0.2 and wherein at least 30 wt% of compounds in the Fischer-Tropsch product have at least 30 carbon atoms, (b) separating the product of step (a) into one or more gas oil fractions and a base oil precursor fraction, (c) performing a pour point reducing step to the base oil precursor fraction obtained in step (b), and (d) separating the effluent of step (c) in two or more base oil grades. |
