Abstract

A gasoline composition containing in the range of from 0.1 to 30 wt % alkylfurfuryl ether with an alkyl group having 1 to 4 carbon atoms is provided. The gasoline composition is prepared by blending the alkylfurfuryl ether in a gasoline base fuel. The alkylfurfuryl ether is prepared by reacting an alkyl alcohol having in the range of 1 to 4 carbon atoms is reacted with furfuryl alcohol by contacting a liquid phase comprising the alkyl alcohol and furfuryl alcohol with an acidic zeolite catalyst at a temperature in the range of from 50 to 200° C.

Claims (15)

1. A gasoline composition comprising in the range of from 0.1 to 30 wt % alkylfurfuryl ether with an alkyl group having 1 to 4 carbon atoms and gasoline base fuel.

2. The gasoline composition of claim 1 wherein the alkylfurfuryl ether is ethylfurfuryl ether.

3. A process for the preparation of a gasoline composition of claim 1 comprising blending in the range of from 0.1 to 30 wt % an alkylfurfuryl ether with an alkyl group having 1 to 4 carbon atoms, with a gasoline base fuel.

4. The process of claim 3 wherein the alkylfurfuryl ether is prepared by reacting an alkyl alcohol having in the range of 1 to 4 carbon atoms with furfuryl alcohol by contacting in a liquid phase comprising the alkyl alcohol and furfuryl alcohol with an acidic zeolite catalyst at a temperature in the range of from 50 to 200° C.

5. The process of claim 4 wherein the temperature is in the range of from 100 to 150° C.

6. The process of claim 4 wherein the molar ratio of alkyl alcohol to furfuryl alcohol that is contacted with the catalyst is in the range of from 0.5 to 20.

7. The process of claim 6 wherein the molar ratio of alkyl alcohol to furfuryl alcohol that is contacted with the catalyst is in the range of from 2 to 20 and the contact time of furfuryl alcohol with the catalyst is controlled such that the total furfuryl alcohol conversion is in the range of from 80 to 95%.

8. The process of claim 6 wherein the molar ratio of alkyl alcohol to furfuryl alcohol that is contacted with the catalyst is in the range of from 0.5 to 2 and the contact time of furfuryl alcohol with the catalyst is controlled such that the total furfuryl alcohol conversion is in the range of from 50 to 80%.

9. The process of claim 4 wherein the alkyl alcohol is an 1-alkanol.

10. The gasoline composition of claim 2 further comprising one or more gasoline additives selected from the group comprising anti-oxidants, corrosion inhibitors, detergents, dehazers, dyes and synthetic or mineral oil carrier fluids.

11. The gasoline composition of claim 1 wherein the alkylfurfuryl ether is present in an amount in the range of from 1 to 10 wt %.

12. The process of claim 9 wherein the alkyl alcohol is methanol or ethanol.

13. The process of claim 12 wherein the alkyl alcohol is ethanol.

14. The process of claim 9 wherein the temperature is in the range of from 100 to 150° C.

15. The process of claim 9 wherein the molar ratio of alkyl alcohol to furfuryl alcohol that is contacted with the catalyst is in the range of from 2 to 20 and the contact time of furfuryl alcohol with the catalyst is controlled such that the total furfuryl alcohol conversion is in the range of from 80 to 95%.
