Definitions

  • the present invention relates to a method for producing an emulsion fuel, and more particularly to a method for producing an emulsion fuel which is a mixture of petroleum and water and which generates a small amount of a substance causing air pollution during combustion.
  • the present invention provides a novel method for producing an emulsion fuel containing a large amount of water that can effectively suppress the generation of substances causing air pollution and capable of stable combustion.
  • Disclosure of the invention
  • the method for producing an emulsion fuel according to the present invention is characterized in that a hydrocarbon oil containing an off-line component is brought into contact with ozone and then reacted by mixing with water to convert it into an emulsion, and further contains an off-line component.
  • the method is characterized in that hydrocarbon oil is brought into contact with ozone while irradiating ultraviolet rays to the presence of the photo-excitable metal oxide catalyst, and then mixed with water to convert to an emulsion.
  • the hydrocarbon oil used as a raw material in carrying out the method for producing the emulsion fuel of the present invention is not limited as long as it contains an oil component, and a petroleum fuel oil such as kerosene or light oil is preferably used.
  • the ozone that reacts with the hydrocarbon oil may be one produced using a known ozone generator or the like, and its concentration is not particularly limited.
  • the metal oxide catalyst used to react hydrocarbon oil with ozone must be photo-stimulable, such as titanium dioxide, zinc oxide, iron dioxide, etc. Titanium is preferred.
  • a metal oxide catalyst can be dispersed in a powder state in a hydrocarbon oil as a raw material, but it may be fixed so as to cover a wall surface or the like of a reaction vessel. It may be used as a stirrer or baffle plate formed by using a catalyst, or a dispersing plate for ozone to be introduced, which is mounted in a reaction vessel.
  • the ultraviolet light source used for reacting the hydrocarbon oil with ozone is not particularly limited as long as it can efficiently emit ultraviolet light of about 180 26 nm.
  • the metal oxide catalyst When reacting hydrocarbon oil with ozone according to the method of the present invention, the metal oxide catalyst is excited by irradiation with ultraviolet light, and the double bond of the olefin and the ozone Is promoted, and ozonide is formed according to the following reaction formula. Then, it becomes aldehyde by ozonolysis.
  • the olefin component contained in the hydrocarbon oil is converted into an aldehyde, and a part of the aldehyde is converted into a hydro aldehyde, that is, an ortho aldehyde by adding water and mixing. Therefore, when a hydrocarbon oil containing such an aldehyde and an orthoaldehyde is mixed with water, the aldehyde and the orthoaldehyde exert a surface-active action to promote emulsification and reduce the resulting emulsion. It is to stabilize.
  • the emulsion fuel thus obtained can contain up to 65% by weight of water and can achieve stable combustion.
  • the emulsion fuel according to the present invention may contain a combustion accelerator, an emulsion stabilizer and other additives as necessary.
  • FIG. 1 is a perspective view showing the structure of a first embodiment of an apparatus for implementing the method for producing an emulsion fuel of the present invention.
  • FIG. 2 is a cross-sectional view of the apparatus shown in FIG. BEST MODE FOR CARRYING OUT THE INVENTION
  • reference numeral 1 denotes a 1.8-liter stainless steel cylindrical container having a titanium oxide powder catalyst 2 provided on the inner wall of the container using epoxy resin as a binder.
  • Reference numeral 3 denotes an ultraviolet irradiation tube of 25 W mm in length and 14 W, which has four tubes capable of generating ultraviolet light in a wavelength range of 180 to 300 nm.
  • Reference numeral 4 denotes a homomixer-type stirrer formed of titanium oxide
  • reference numeral 5 denotes an air diffuser provided with a titanium oxide layer on the surface, similarly to the container 1.
  • 6 is a hydrocarbon oil inlet
  • 7 is a water inlet
  • 8 is an exhaust port
  • 9 is a liquid outlet.
  • 400 g of kerosene with an equivalent amount of ZKg of unsaturated double bond is injected from hydrocarbon oil inlet 6 of this reactor, and oxygen containing 580 ppm ozone generated by another ozone generator is diffused from diffuser 5. Blowing was performed at a rate of 2 liters per minute, and all the ultraviolet irradiation tubes 3 were turned on and reacted at room temperature for 15 minutes while stirring.
  • the oil-water-400Z600 emulsion fuel thus obtained was a milky liquid and was stable after standing for 5 hours.
  • the fuel self-combusted stably at a furnace temperature of 900, and the concentration of NOx in the combustion gas was 40 ppm.
  • the emulsified fuel obtained by emulsification using a surfactant with the ratio of kerosene to water set to 500/500 did not self-burn, and measurement of NOx was impossible.
  • the concentration of NOx in the combustion gas when burning only kerosene was 180 ppm.
  • a reactor was prepared by removing all the ultraviolet irradiation tubes 3 in the reactor shown in FIG. 1 described above, and kerosene 4 having an equivalent equivalent of unsaturated double bond Z Kg 4 was obtained from the hydrocarbon oil inlet 6 of this reactor.
  • oxygen containing 580 ppm ozone generated by another ozone generator was blown in from the diffuser 5 at a rate of 2 liters per minute for 1 minute, and stirred with the stirrer 4 for 20 minutes.
  • the reaction was carried out at room temperature for minutes.
  • 600 g of water was poured from the water inlet 7 and the mixture was stirred for 7 minutes to react the ozonized kerosene with the water and at the same time to emulsify.
  • the oil-Z water ratio which was conventionally considered to be unable to perform stable self-combustion, can be self-combustible while containing a large amount of water such as 400 to 600 An emulsified fuel can be obtained, and combustion can be performed at a lower temperature than before, which has the effect of greatly reducing the generation of air pollutants.

Abstract

Nouveau procédé de production d'un carburant émulsionné qui contient suffisamment d'eau pour réguler efficacement la production de polluants atmosphériques et qui est capable de brûler de manière stable. Selon ce procédé on soumet une huile hydrocarbure contenant de l'oléfine et de l'ozone à une réaction catalytique, puis on ajoute de l'eau dans le produit de réaction pour l'émulsionner. Le carburant peut brûler spontanément jusqu'à avoir une teneur en eau de 65 % environ.
