Emulsifier for water-in-oil emulsion fuel

Abstract

Provided is an emulsifier for a water-in-oil (W / O) emulsion fuel wherein reseparation between oil and water does not take place for a long period of time because of stable emulsion state with homogeneous dispersion. The emulsifier of the present invention for a water-in-oil emulsion fuel comprises following (1) to (7) components: (1) heavy oil A: 50 mL or more 100 mL, (2) heavy oil B: 100 mL or more 200 mL, (3) heavy oil C: 300 mL or more 450 mL, (4) methanol: 100 mL or more 150 mL, (5) ethanol: 100 mL or more 200 mL, (6) palm oil: 100 mL or more 150 mL, and (7) water: 100 mL or more 200 mL.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a method for producing an emulsifier for a water-in-oil (W / O) emulsion fuel, wherein the emulsifier can provide a water-in-oil fuel that has extremely good stability of emulsion state between an oil fuel (light oil and heavy oil) and water whereby reseparation between oil and water does not take place for a long period of time (two years or more).[0003]Further, the present invention has an object to prevent pollution by drastically reducing harmful gases and soot / dust emitted in large quantities during burning of an oil fuel (both light oil and heavy oil) and at the same time to improve fuel efficiency by complete burning thereby contributing to an energy saving effect.[0004]2. Description of the Related Art[0005]In the past, an emulsion fuel has been used, as an emulsifier, a chemical such as monoethanol amine, triethanol amine, oleic acid, an aliphatic sulfonate salt, and an alcohol al...

AI Technical Summary

Benefits of technology

[0006]The present invention solved the problems as mentioned above thoroughly; and thus, storage management can be done in a similar manner to that of a pure oil fuel because an oil and water do not reseparate for a long period of time (two years or more) with keeping a stable emulsion state with homogeneous dispersion; and in addition, an expensive emulsifying equipment and a special burning technique are not necessary because the fuel can be used as it stands in an oil tank and an existing burning appliances can be used.

Problems solved by technology

In the past, an emulsion fuel has been used, as an emulsifier, a chemical such as monoethanol amine, triethanol amine, oleic acid, an aliphatic sulfonate salt, and an alcohol aliphatic acid ester; but these chemicals are expensive thereby leading to a high production cost of the fuel.

In addition, an emulsion fuel produced by mixing with these chemicals is unstable in emulsion state thereof, thereby causing reseparation between an oil and water in a short time after production; and thus, burning must be done simultaneously with emulsification by installing an emulsifying equipment together with burning appliances, so that storage management of the fuel itself is impossible.

Accordingly, an economic merit is small to many consumers of general small and medium-sized enterprises in view of burning technique and high cost of an emulsifying equipment.
