Abstract
Provided are a method of producing a Lube base oil composition including a) reacting at least a part of waste plastic pyrolysis oil having a boiling point in a range of 180 to 340° C. to remove impurities and oligomerize the oil; and b) hydroisomerizing at least a part of the product of step a). A lube base oil composition is also produced therefrom.
Claims8
A method of producing a lube base oil composition, the method comprising the steps of:
- a) separating at least a part of a waste plastic pyrolysis oil into a first oil fraction having a boiling point in a range of 180 to 340° C.;
- b) reacting the first oil fraction having a boiling point in a range of 180 to 340° C. with a solid acid material to remove impurities and oligomerize the oil;
- and
- c) hydroisomerizing at least a part of the product of the process a),
- wherein the process c) of hydroisomerization satisfies the following Relation 1:
- 0.95<A/B<1.05 [Relation 1]
- wherein A and B are weight average molecular weights of the waste plastic pyrolysis oil from which impurities have been removed before hydroisomerization treatment (A) and after hydroisomerization treatment (B), respectively.
