Definitions

• This invention relates to an additive for liquid and gaseous hydrocarbon fuels to improve the combustion thereof. More specifically, this invention relates to the use of the alcohol heptadecanol in small or trace quantities to substantially increase the energy released upon the combustion of hydrocarbon fuels.
• Heptadecanol is a generic name for the several isomeric forms of the aliphatic alcohol having the empirical formula C H OH. It is usually produced commercially in the branched form 3,9-diethyl-6-hydroxyl tridecane, which has the structure,
• Heptadecanol has been used in the past chiefly for the synthesis of more complex organic materials, as a plasticizer, a perfume fixative, and as a base for the manufacture of wetting agents and detergents.
• This invention is predicated on the empirical discovery and determination that very small or trace quantities of heptadecanol will effect a highly surprising improvement in the combustion properties of various carbon and hydrocarbon fuels, including liquid fuels such as gasoline, kerosene, and fuel oil, gaseous hydrocarbon fuels, and coal and coke.
• this improvement may appear as an improvement in the measured release of B.t.u.s per unit time, or it may change the character of the flame or the rate of combustion so that more recoverable heat is released. In any event, the improvements I have discovered can be obtained are truly remarkable.
• Heptadecanol is a liquid at ordinary temperatures. It is soluble in a wide range of hydrocarbon liquids and can be incorporated in various grades of liquid hydrocarbon fuels simply by mixing it with the fuel to form a dispersion or solution. In the case of fuel oil the heptadecanol can be added in the proportions of about &- 100 cc. per gallons of oil, but about 1 or 2 cc. presently appears to give best results at the least cost, and larger amounts do not now appear to give commensurately better results. It is contemplated that the quantity of additive used will vary with the specific fuel to which it is added, and also with the conditions under which the fuel burns, and therefore I do not wish to be limited to any specific range of addition. The fuel may be burned in the conventional manner, although it is usually necessary to increase the air/fuel ratio to provide best results.
• gaseous hydrocarbon fuels including both natural gas and synthetic fuels
• heptadecanol immediately prior to combustion.
• heptadecanol is a liquid having a low vapor pressure, it goes into the .gas stream at a very slow rate, and apparently Works its improvement as a catalyst in some manner not fully understood.
• composition of matter a mixture containing as its essential components fuel oil mixed with hepta- 4 decanol in the proportion of about 0.5 cc. heptadecanol per 15 gallons fuel oil.
• composition of matter a mixture consisting essentially of heptadecanol and a fuel of the class consisting of kerosene and fuel oil, in the proportions of about /2-100 cc. heptadecanol per 15 gallons fuel.
