Problems solved by technology

Second, since the continuous phase is oil and not water, it does not expose the water to the ignition source first, and therefore does not immediately cool the intake air, resulting in a low effect of the water in the emulsion to produce clean combustion
Third, due to stability issues, the content of organic oxides in this type of system is limited
Compared with standard fuels, the disadvantage of this type of emulsified fuel is that the power is sluggish, especially in conditions where there is no power loss (such as non-stationary engines), this disadvantage is more prominent

Embodiment 1～24 and comparative example A to C

[0029] Dual fluid fuel compositions were prepared in 50 g batches by adding 67 ml of a pre-stirred mixture of methanol, ethanol and / or ethylene glycol with water and surfactant to a 250 ml quartz beaker. A four-bladed axial flow impeller with a diameter of 55 mm was lowered into the beaker and rotated at a rate of 200 rpm, agitating the aqueous phase to ensure that the impeller cuts the gas / liquid interface. Slowly add the fuel dropwise into the water phase within 10-15 minutes. After all the fuel had been added, the mixture was stirred for an additional 15 minutes to form the desired dual liquid fuel composition.

[0030] As shown in Table 1, the resulting composition comprised, by weight, 80% diesel, 1% surfactant, and 19% alcohol-water mixture. The column of the percentage of alcohol in Table 1 refers to the percentage of alcohol in the alcohol-water mixture.

[0031] The compositions in Comparative Examples A, B and C contained surfactants Protachem CAH-16, Etocas 15 and...

Embodiment 25

[0035] Substitute diesel oil with unleaded gasoline, repeat the process of embodiment 1. The resulting bifluid fuel was stable for 64 days, after which some instability was observed.

Embodiment 26

[0037] Substitute diesel oil with kerosene, repeat the process of embodiment 1. The resulting bifluid fuel was stable for 43 days before the samples began to show signs of instability.

Abstract

A fuel composition which comprises a biliquid foam consisting of from 10% to 97.5% by weight of non-coalescing droplets of a non-polar liquid comprising a petroleum derivative, paraffin or a liquid halogenated hydrocarbon and from 2 to 87% by weight of a continuous phase polar liquid comprising a C1-C3 alcohol, a C4 alcohol containing at least two hydroxy groups, or ethylene glycol, or mixtures thereof, in an amount of from 60% to 100% by weight thereof, wherein the biliquid foam is stabilized with an amount of from 0.5 to 3.0% by weight based on the total formulation of a surfactant which is selected from castor oil / poly(alkylene glycol) adducts containing from 20 to 50 alkoxy groups, or hydrogenated castor oil / poly(alkylene glycol) adducts containing from 20 to 60 alkoxy groups, or mixtures thereof.

Description

technical field [0001] The present invention relates to polyaphron (otherwise known as two-fluid foam) compositions, and in particular to polyaphron fuel compositions having a high content of saturated organic oxides in the continuous phase. Background technique [0002] The main irritants and pollutants in the atmosphere are nitrogen oxides. Environmental pressures and government regulations to reduce NO emissions from internal combustion engines x requirements are becoming increasingly stringent. One of the problems with diesel fueled internal combustion engines is the increased tendency of nitrogen from the air or nitrogen-containing compounds in the fuel to be oxidized to nitrogen oxides due to the relatively high temperatures reached by combustion. To reduce NO x Some methods have been proposed, including using catalytic converters, using clean fuels, and adjusting the engine's regulating mechanism. However, none of these methods has been widely used. The generatio...
