Oil-water emulsion as diesel fuel - contains heavy oils from petroleum, coal, or vegetable sources

摘要

Fuel/water emulsions for use in diesel engines contain 12-20% water (I), 0.5-1.5% of an emulsifier (II) contg. an alkylphenol polyglycolether, and approx. 80 vol.% of a fuel (III).(III) contains at least 10% middle oil (IIIa), the remainder being heavy oils (IIIb). (IIIa) can be a mineral or synthetic diesel oil, incl. oil from coal hydrogenation; and (IIIb)can be rape or other vegetable oil, petroleum heavy oil, recovered oil, oil residues, oil from coal hydrogenation and mixts. of these. The requirement for petroleum fractions, becoming scarcer, is reduced. The max. viscosity for a useable emulsion is greater than for an oil alone.
