Abstract
Abstract A long chain macro-molecule synthetic fuel derived by distillation-linking methanol, butanol and a kerosene type oil with a colloid stabilizer. The synthetic fuel, when mixed with conventional fuels, substantially reduces the generation of carbon monoxide, unburned hydrocarbons and nitrous oxides as combustion products.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
41 words
A synthetic fuel comprising 20 to 40 percent by volume butanol, 10 to 40 percent by volume methanol, 20 to 60 percent by volume heavy hydrocarbon, and 0.0001 to 0.001 pound of a colloid stabilizer per gallon of the remaining constituents.
Claim 2
Dependent Claim
41 words
A synthetic fuel comprising 20 to 40 percent by volume butanol, 10 to 40 percent by volume methanol, 20 to 60 percent by volume heavy hydrocarbon, and 0.0001 to 0.001 pound of a colloid stabilizer per gallon of the remaining constituents.
Claim 3
Dependent Claim
28 words
A synthetic fuel as recited in claim 1, wherein said heavy hydrocarbon is selected from the group of heavy hydrocarbons consisting of naptha, coal oil, and vegetable oil.
Claim 4
Dependent Claim
16 words
A synthetic fuel as recited in claim 1, wherein said colloid stabilizer is magnesium laurel salts.
Claim 5
Dependent Claim
37 words
A synthetic fuel as recited in claim 1 comprising 20 percent by volume butanol, 40 percent by volume methanol, 40 percent by volume heavy hydrocarbon, and 0.001 pound of colloid stabilizer per gallon of the remaining constituents.
Claim 6
Independent Claim
80 words
The method of preparing a synthetic fuel, said method comprising the steps preparing a mixture of 20 to 40 percent by volume butanol, 10 to 40 percent by volume methanol, and 20 to 60 percent by volume heavy hydrocarbon; adding to said mixture 0.0001 to 0.001 pound of a colloid stabilizer per gallon of said mixture; heating said mixture to a temperature sufficient to vaporize said mixture; condensing said vaporized mixture to a liquid state; and collecting the condensed mixture.
Claim 7
Independent Claim
80 words
The method of preparing a synthetic fuel, said method comprising the steps preparing a mixture of 20 to 40 percent by volume butanol, 10 to 40 percent by volume methanol, and 20 to 60 percent by volume heavy hydrocarbon; adding to said mixture 0.0001 to 0.001 pound of a colloid stabilizer per gallon of said mixture; heating said mixture to a temperature sufficient to vaporize said mixture; condensing said vaporized mixture to a liquid state; and collecting the condensed mixture.
Claim 8
Dependent Claim
27 words
The method as recited in claim 5, wherein said heavy hydrocarbon is selected from the group of heavy hydrocarbons consisting of naptha, coal oil, and vegetable oil.
Claim 9
Dependent Claim
15 words
The method as recited in claim 5, wherein said colloid stabilizer is magnesium laurel salts.
Claim 10
Dependent Claim
14 words
The method as recited in claim 5 wherein said temperature in 300 degrees Fahrenheit.
Claim 11
Dependent Claim
45 words
The method as recited in claim 5, wherein said mixture is prepared in the proportion of 20 percent by volume butanol, 40 percent by volume methanol and 40 percent by volume heavy hydrocarbon to which is added 0.001 pound of said colloid stabilizer per gallon.
Claim 12
Dependent Claim
21 words
The method as recited in claim 9, wherein said heavy hydrocarbon is naptha and said colloid stabilizer is magnesium laurel salts.
Claim 13
Dependent Claim
22 words
The method as recited in claim 9 further including the step of mixing said synthetic fuel with gasoline in a predetermined ratio.
Claim 14
Dependent Claim
24 words
The method as recited in claim 10 wherein said ratio is 75 percent by volume gasoline and 25 percent by volume said synthetic fuel.
