Abstract

A process for preparing a gasoline octane boosting composition, including contacting a pyrolysis oil with a non-thermal oxygen plasma to produce an oxidized pyrolysis oil; and mixing the oxidized pyrolysis oil with a gasoline additive to produce the gasoline octane boosting composition. The gasoline octane boosting composition can be used in a gasoline blend.

First claim

The invention claimed is:

1. A process for preparing a gasoline octane boosting composition, the process comprising:
contacting a pyrolysis oil with a non-thermal oxygen plasma to produce an oxidized pyrolysis oil; and
combining the oxidized pyrolysis oil with a gasoline additive to produce the gasoline octane boosting composition.

2. The process according to claim 1 , further comprising generating the non-thermal oxygen plasma at 0.1 to 1 mbar, 0.5 to 10 kV, and 20 to 1000 W/g.

3. The process according to claim 1 , wherein the contacting is carried out for 30 seconds to 5 minutes and the oxidized pyrolysis oil produced comprises unoxidized hydrocarbons and an oxidation product comprising a primary alcohol, a diol, a polyol, or a combination comprising at least one of the foregoing.

4. The process according to claim 1 , wherein the contacting is carried out for 5 to 30 minutes and the oxidized pyrolysis oil comprises unoxidized hydrocarbons and an oxidation product comprising a primary alcohol, secondary alcohol, diol, polyol, aldehyde, ketone, or a combination comprising at least one of the foregoing.

5. The process according to claim 1 , wherein the oxidized pyrolysis oil has a blending research octane value of greater than 100.

6. The process according to claim 1 , wherein the oxidized pyrolysis oil has a Saybolt number of at least +5.

7. The process according to claim 1 , wherein the oxidized pyrolysis oil has a Reid vapor pressure of 3 to 6 psi.

8. The process according to claim 1 , wherein the oxidized pyrolysis oil has a density of 0.8 to 0.95 kg/L.

9. The process according to claim 1 , wherein the oxidized pyrolysis oil is combined with the gasoline additive at an oxidized pyrolysis oil:gasoline additive volume ratio of 1:199 to 1:3.

10. The process according to claim 1 , wherein the gasoline additive comprises methanol, ethanol, isopropyl alcohol, n-propyl alcohol, isobutanol, n-butanol, sec-butyl alcohol, tert-butyl alcohol, gasoline grade tert butyl alcohol, tert-amyl alcohol, methyl tert-butyl ether, ethyl tert-butyl ether, tert-amyl methyl ether, tert-amyl ethyl ether, tert-hexyl methyl ether, diisopropyl ether or a combination comprising at least one of the foregoing, preferably wherein the gasoline additive is methyl tert-butyl ether.

11. A gasoline octane boosting composition produced by the process of claim 1 .

12. The gasoline octane boosting composition according to claim 11 , having a blending research octane value of 105 to 120 and a blending motor octane value of 95 to 105.

13. The gasoline octane boosting composition according to claim 11 , wherein the composition, when added to a base gasoline up to a final volume percentage of 15 vol. %, changes the Reid vapor pressure of the base gasoline by ±0.5 to ±1 psi.

14. A gasoline blend comprising:
85 to 99 vol. % of a fuel-grade base gasoline; and
1 to 15 vol. % of the gasoline octane boosting composition according to claim 13 .

15. The gasoline blend according to claim 14 , having an oxygen content of 4 to 10 wt. % based on the weight of the base gasoline.
