Abstract
Emulsions of a hydrocarbon and water in which the hydrocarbon preferably is a Fischer-Tropsch derived hydrocarbon fuel and in which emulsion a major portion of the hydrocarbon has particle sizes of 1 micron or less produce reduced particulate matter emissions upon combustion.
Claims12
A method for reducing particulate emissions during combustion of a hydrocarbon fuel which comprises combusting an emulsion of a hydrocarbon fuel and water wherein the fuel is a Fischer-Tropsch (FT) derived hydrocarbon as a mixture of a FT fuel and a conventional fuel, and in which emulsion, a major portion of the hydrocarbon has particle sizes of 1 micron or less.
A method for forming a fuel in water emulsion which when combusted has reduced particulate matter emissions compared with Swedish Class I Diesel Fuel comprising shearing a Fischer-Tropsch derived hydrocarbon boiling in the diesel fuel range and water in the volume ratio of hydrocarbon to water of 95:5 to 40:60 and about 0.05 to about 5.0 wt % based on the weight of hydrocarbon and water with a non-ionic surfactant or mixtures thereof having a HLB of about 5 to about 30 under shearing conditions sufficient to produce a liquid emulsion in which a major portion of the hydrocarbon has particle sizes of 1 micron or less.
A liquid fuel composition comprising an emulsion of FT derived fuel in water wherein the fuel in the emulsion has fuel particle sizes predominately of 1 micron or less and the emulsion has a viscosity of above about 50 mm2/sec at 20° C.
