Abstract
Abstract A composition and method for producing a multiple boiling point ether gasoline component is provided. A mixed alcohol composition including predominantly C1-C3 alcohols is reacted with an alkene stream to produce a mixture of ethers having different boiling points. The ether mixture is useful, when blended with gasoline, to increase oxygenation and overall motor fuel performance.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
47 words
A method for producing a mixed ether and gasoline containing composition to form an oxygenated fuel mixture comprising the steps of reacting a mixture containing C 1 -C 8 alcohols with an alkene, to form an alkyl-t-alkyl mixed ether composition; and mixing said ether composition with gasoline.
Claim 2
Independent Claim
47 words
A method for producing a mixed ether and gasoline containing composition to form an oxygenated fuel mixture comprising the steps of reacting a mixture containing C 1 -C 8 alcohols with an alkene, to form an alkyl-t-alkyl mixed ether composition; and mixing said ether composition with gasoline.
Claim 3
Dependent Claim
25 words
The method of claim 1 wherein said alcohol mixture is predominantly methanol and includes at least about 25% (v/v) alcohol having two or more carbons.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said alcohol mixture is predominantly ethanol and isopropanol.
Claim 5
Independent Claim
20 words
The method of claims 1 wherein said alcohol mixture includes methanol, ethanol, propanol and butanol and said alkene is isobutylene.
Claim 6
Dependent Claim
20 words
The method of claim 1 wherein said alcohol mixture includes methanol, ethanol, propanol and butanol and said alkene is isoamylene.
Claim 7
Dependent Claim
21 words
The method of claim 1 comprising the additional step of reacting a hydrocarbon containing source stream to produce said alcohol mixture.
Claim 8
Dependent Claim
25 words
The method of claim 1 wherein said ether composition is mixed in an amount sufficient to form a 15% (v/v) mixture based on said gasoline.
Claim 9
Dependent Claim
19 words
The method of claim 1 wherein said alcohol mixture further comprises water in an amount greater than 0.1% (v/v).
Claim 10
Dependent Claim
40 words
A composition comprising a mixture of 85% gasoline and 15% of an ether containing product, said ether containing product being formed by the steps of preparing a blend of C 1 -C 8 alcohols and reacting said blend with isoamylene.
Claim 11
Dependent Claim
40 words
A composition comprising a mixture of 85% gasoline and 15% of an ether containing product, said ether containing product being formed by the steps of preparing a blend of C 1 -C 8 alcohols and reacting said blend with isoamylene.
