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.

What is claimed is: 
     
         1 . An emulsifier for a water-in-oil emulsion fuel, wherein the emulsifier comprises following components (1) to (7):
 (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   (7) Water: 100 mL or more 200 mL
