Abstract
Provided is a crude oil additive comprising a pyrolysis oil fraction. In some embodiments, the crude oil additive further comprises a dispersant. Also provided are methods of preparing the crude oil additive as well as methods for reducing the viscosity of crude oil and methods for increasing the API gravity of crude oil.
Claims24
A crude oil additive comprising a pyrolysis oil fraction and a dispersant;
- wherein the dispersant is a naphtha;
- and
- wherein the additive is substantially free of unfractionated pyrolysis oil.
A crude oil additive comprising a pyrolysis oil fraction and a dispersant selected from the group consisting of a naphtha, xylene, toluene, benzene, n-heptane, and styrene, wherein:
- the additive is substantially free of unfractionated pyrolysis oil, and
- the percentage of terpene in the pyrolysis oil fraction is less than 1% (v/v).
A crude oil additive comprising a pyrolysis oil fraction and a dispersant selected from the group consisting of a naphtha, xylene, toluene, benzene, n-heptane, and styrene, wherein the pyrolysis oil fraction does not comprise limonene.
A crude oil additive comprising a pyrolysis oil fraction and a dispersant selected from the group consisting of a naphtha, xylene, toluene, benzene, n-heptane, and styrene, wherein the pyrolysis oil fraction does not comprise cymene.
A method of reducing the viscosity of crude oil comprising
- adding a crude oil additive comprising a pyrolysis oil fraction and a dispersant selected from the group consisting of a naphtha, xylene, toluene, benzene, n-heptane, and styrene;
- wherein the additive is substantially free of unfractionated pyrolysis oil;
- to crude oil,
- thereby reducing the viscosity of the crude oil.
