Abstract

An emulsifying composition which includes an ethoxylated alkylphenol, a fatty acid amide, naphtha and oleic acid. The composition is used for emulsifying fuel and water mixtures in internal combustion engines, open flame burners (boilers) or the like. Preferably the composition includes one part polyoxyethylene-nonylphenol, two parts coconut diethanolamide, two parts heavy naphtha and one part oleic acid, by volume. The invention also extends to a hydrocarbon fuel including a composition in accordance with the invention and to a method of forming a hydrocarbon fuel and water emulsion including the composition.

Claims

exact text as granted — not AI-modified
1 . An emulsifying composition which includes 
 an ethoxylated alkylphenol;    a fatty acid amide;    naphtha; and    oleic acid.    
   
   
       2 . A composition as claimed in  claim 1 , in which the ethoxylated alkylphenol is polyoxyethylene (POE)-nonylphenol.  
   
   
       3 . A composition as claimed in  claim 1 , in which the fatty acid amide is a fatty acid dialkanolamide.  
   
   
       4 . A composition as claimed in  claim 3 , in which the fatty acid dialkanol amide is coconut diethanolamide.  
   
   
       5 . A composition as claimed in  claim 1 , in which the naphtha is heavy naphtha.  
   
   
       6 . A composition as claimed in  claim 1 , in which the ethoxylated alkylphenol is a polyoxyethylene-nonylphenol, the fatty acid amide is coconut diethanolamide and the naphtha is heavy naphtha, and in which the composition contains one part polyoxyethylene-nonylphenol, two parts coconut diethanolamide, two parts heavy naphtha and one part oleic acid, by volume.  
   
   
       7 . A hydrocarbon fuel which includes a composition as claimed in  claim 1 .  
   
   
       8 . A hydrocarbon fuel as claimed in  claim 7 , which includes up to 40% water, by volume.  
   
   
       9 . A hydrocarbon fuel as claimed in  claim 8 , which includes up to 25% water, by volume.  
   
   
       10 . A hydrocarbon fuel as claimed in  claim 7 , which includes between 1.5% and 2%, by volume, of the emulsifying composition.  
   
   
       11 . A method of forming a hydrocarbon fuel and water emulsion which includes adding an ethoxylated alkylphenol, a fatty acid amide, naphtha and oleic acid to a hydrocarbon fuel to form a mixture and adding water to said mixture.  
   
   
       12 . A method as claimed in  claim 11 , which includes forming an additive composition containing the ethoxylated alkylphenol, the fatty acid amide, the oleic acid and the naphtha and adding said additive composition to the hydrocarbon fuel.  
   
   
       13 . A method as claimed in  claim 12 , in which the additive composition includes one part polyoxyethylene-nonylphenol, two parts coconut diethanolamide, one part oleic acid, by volume, and two parts heavy naphtha, by volume.  
   
   
       14 . A method as claimed in  claim 12 , in which the additive composition is formed by mixing its constituents in the order polyoxyethylene-nonylphenol, coconut diethanolamide, oleic acid and naphtha.
