Abstract

A fuel additive for a hydrocarbon based fuel that has one or more of the following Components: Component A; a non-ionic surfactant having the formula wherein R is an alkyl radical having from 4 to 20 carbon atoms, preferably 6 to 10 carbon atoms, and n is an integer of from 2 to 8; Component B; a compound selected from the group consisting of partially sulfonated naphthalene formaldehyde condensates, polymer condensates of linear alkyl benzene sulfonic acids, and naphthalene sulfonic acids with formaldehyde and mixtures thereof; Component C; a polycarboxylate-type material comprising at least one of a ammonium polyacrylate, a polyacrylate derivative, a hydrophobic copolymer, or a hydrophobically modified acrylic polymer having a pH of from about 6.0 to about 7.0; Component D; a finely divided poly alpha olefin; or Component E; any combination of A, B, C, or D.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A fuel additive for a hydrocarbon based fuel comprising at least one of:
 Component A a non-ionic surfactant having hydrophobic-hydrophilic constituents in the molecule and having the formula:   
       
         
           
           
               
               
           
         
       
       wherein R is an alkyl radical having from 4 to 20 carbon atoms, preferably 6 to 10 carbon atoms, and n is an integer of from 2 to 8;
 Component B a compound selected from the group consisting of partially sulfonated naphthalene formaldehyde condensates, polymer condensates of linear alkyl benzene sulfonic acids, and naphthalene sulfonic acids with formaldehyde and mixtures thereof; 
 Component C a polycarboxylate-type material comprising at least one of a ammonium polyacrylate, a polyacrylate derivative, a hydrophobic copolymer, or a hydrophobically modified acrylic polymer having a pH from about 6.0 to about 7.0; 
 Component D a finely divided poly alpha olefin; or 
 Component E any combination of A, B, C, or D. 
 
     
     
         2 . The fuel additive of  claim 1 , comprising Component D and at least one of Component B or Component C. 
     
     
         3 . The fuel additive of  claim 2 , comprising Component D and Component B. 
     
     
         4 . The fuel additive of  claim 2 , comprising Component D and Component C. 
     
     
         5 . The fuel additive of  claim 2 , comprising Component D, Component B and Component C. 
     
     
         6 . The fuel additive of  claim 1 , wherein said polyalpha olefin is produced from alpha olefins containing between 4-20 carbon atoms. 
     
     
         7 . The fuel additive of  claim 6 , wherein said polyalpha olefin contains between 6-14 carbon atoms. 
     
     
         8 . The fuel additive of  claim 1 , wherein said polyalpha olefin is produced from alpha olefins having an average of 10 carbon atoms. 
     
     
         9 . The fuel additive of  claim 6 , wherein the molecular weight of the polyalpha olefin is from about 300,000 to about 2,000,000. 
     
     
         10 . The fuel additive of  claim 6 , wherein said polyalpha olefin has a particle size of from 25 microns to 100 microns. 
     
     
         11 . The fuel additive of  claim 5 , wherein Component B is present in an amount of from about 4.5 wt % to about 9.0 wt %, Component C is present in an amount from about 0.2 wt % to about 1.0 wt %, and Component D is present in an amount from about 85 wt % to about 99 wt %. 
     
     
         12 . The fuel additive of  claim 3 , wherein Component B is present in an amount from about 4.0 wt % to about 10 wt %, and Component D is present in an amount from about 90 wt % to about 99 wt %. 
     
     
         13 . The fuel additive of  claim 4 , wherein Component D is present in an amount from about 92 wt % to about 99 wt % and Component C is present in an amount from about 0.2 wt % to about 1.0 wt %. 
     
     
         14 . The fuel additive composition of  claim 1  comprising an adjunct selected from the group consisting of biocides, thickening agents and mixtures thereof. 
     
     
         15 . A fuel composition comprising a hydrocarbon containing fuel and a fuel additive according to  claim 1 . 
     
     
         16 . The fuel composition of  claim 15 , wherein the hydrocarbon fuel comprises diesel. 
     
     
         17 . The fuel composition of  claim 15 , wherein the hydrocarbon fuel comprises gasoline.
