Abstract (en)
[origin: WO8600333A1] Improved fuels having significantly increased combustion efficiencies, desirable octane ratings and lowered polution emissions which are supplemented by a minor amount of a polyolefinic additive containing recurring C2-C10 monomer moieties therein. The fuels preferably include a liquid hydrocarbon such as a gasoline or diesel fuel, with up to about 2.5% by weight polyolefin, or in certain cases a polyolefin derivative. The most preferred additive for use in the fuel of the invention is polybutene. Stable emulsified fuels are also provided which comprise respective fractions of water, liquid combustible hydrocarbon, one or more surfactants, and a polyolefin additive. Test results demonstrate that the fuels of the invention exhibit greater work output per pound of fuel than straight unmodified comparative fuels. The presence of polyolefins in the fuel is believed to generate reactions analogous to cracking during combustion of the fuel compositions, with the resultant exothermic heats of reaction adding substantially to the caloric values obtained from the fuels; in the case of emulsified fuels for example, this factor is believed to compensate for the potential caloric loss represented by the presence of significant amounts of water.
