Abstract:
A new liquid fuel is prepared by mixing an emulsion which is a mixture of one portion of lubricating oil with not more than three portions of water, into diesel oil, or by adding water to a mixture of A and C heavy oil. The new liquid fuel causes no pollution and maintains internal combustion engines clean with prices inexpensive.
Abstract:
An emulsified combustible fuel is prepared by mixing the fuel with 10 to 50 wt. % of a water mixture containing 0.01 to 1.0 parts by weight of an anionic surfactant, 0.01 to 0.5 parts by weight of polyethylene oxide and 0.001 to 0.2 parts by weight of mathothyl per 100 parts by weight of water. The emulsified fuel can reduce the amount of discharged pollutants by optimizing combustion, thereby saving energy due to high efficiency. Further, it can be used in small, medium or large boiler systems without any control means to constantly maintain the optimal ratio of combustible fuel to water.
Abstract:
A multiple emulsion includes a continuous water phase; an oil droplet phase dispersed through the continuous water phase; an inner water droplet phase dispersed through the oil droplet phase; and a water insoluble compound suspended in the inner water droplet phase. The multiple emulsion is useful as a transportable and combustible fuel.
Abstract:
A heavy hydrocarbon, oil-in-water emulsion that has a relatively low viscosity for improved transport is disclosed. The emulsion is produced by combining the heavy hydrocarbon with an aqueous solution of emulsifier with agitation. The emulsifier has an HLB value of about 13 to about 16. The emulsifier can be anionic, nonionic, amphoteric, or a mixture thereof. Stirring is effected at medium shear values of about 0.1 sec.sup.-1 to about 20 sec.sup.-1 and at a mixer speed of 50 to 2000 rpm. The mixer imparts sufficient power and shear to the emulsion so that a mean oil droplet size of about 30 .mu.m is obtained.
Abstract:
A novel diesel engine fuel is in the form of a pyrolysis liquid-in-diesel oil microemulsion fuel comprising: (a) diesel oil in an amount sufficient to form a continuous phase in the composition; (b) a pyrolysis liquid forming a discontinuous phase in the composition, this pyrolysis liquid being a liquid obtained by rapid pyrolysis of biomass; and (c) at least one emulsifier selected from nonionic hydrophilic surfactants with HLB between 4 and 18, derived from fatty acids and polyoxyethylene glycol, or fatty acids, sorbitol and polyoxyethylene or polyethoxylated alcohols with long aliphatic chains. This fuel has excellent stability and physical properties similar to those of regular diesel fuel.
Abstract:
A method of and apparatus for manufacturing hydrous oil are provided low frequency and low voltage and current signals are applied to a water supply pipe system and a low frequency and low voltage and current signal is applied to an oil supply system. The water and oil mix with each other at a mixing point and a plurality of low frequency and low voltage and current signals are applied to a mixing supply system formed by joining the water supply pipe system and oil pipe system. The mixture of water and oil is subjected to emulsification in a heater-equipped emulsion tank and the emulsification is facilitated with the aid of air so as to produce the hydrous oil. After a low frequency and low voltage and current signal is applied to the hydrous oil, air is supplied to the hydrous oil in an aeration tank. Further, after a low frequency and low voltage current signal is applied to the hydrous oil, the hydrous oil is flowed in a storage tank.
