Abstract
A process for upgrading a pyrolysis oil comprising treating the pyrolysis oil with an upgrading solution to provide a mixture comprising an extract phase and a raffinate phase, wherein the upgrading solution comprises a polar organic solvent, and wherein the pyrolysis oil is a derived from the pyrolysis of plastic or rubber, or a combination thereof, and an upgraded pyrolysis oil prepared by said process.
Claims20
A process for upgrading a pyrolysis oil comprising treating the pyrolysis oil with an upgrading solution to provide a mixture comprising an extract phase and a raffinate phase and the further step of treating the raffinate phase with an adsorbent, wherein the upgrading solution comprises a polar organic solvent, and wherein the pyrolysis oil is a derived from the pyrolysis of plastic or rubber, or a combination thereof.
A process for producing an upgraded pyrolysis oil product comprising:
- (i) treating a pyrolysis oil with an upgrading solution, wherein the upgrading solution comprises a polar organic solvent;
- (ii) mixing the pyrolysis oil and the upgrading solution and then allowing the mixture to form two phases consisting of a raffinate phase and an extract phase;
- (iii) separating the raffinate phase from the extract phase to yield an upgraded pyrolysis oil product, and
- (iv) treating the raffinate phase with an adsorbent;
- wherein the pyrolysis oil is derived from the pyrolysis of plastic or rubber, or a combination thereof.
A process for producing an upgraded pyrolysis oil product comprising:
- (i)(a) treating a pyrolysis oil with an upgrading solution, wherein the upgrading solution comprises a polar organic solvent;
- (i)(b) optionally treating the product of (i)(a) with a hydrocarbon fluid;
- (ii) mixing the mixture obtained from (i)(a), or optionally (i)(b), and then allowing the mixture to form at least two phases comprising a raffinate phase and an extract phase, and
- (iii) separating the raffinate phase from the extract phase;
- (iv) treating the separated raffinate phase of step (iii) with an adsorbent;
- wherein the pyrolysis oil is derived from the pyrolysis of plastic or rubber, or a combination thereof.
