Diesel additive, preparation method and usage method thereof

Abstract

The present invention relates to a diesel additive. The diesel additive comprises 80-100 wt. % of a nonylphenol polyether amine and 0-20 wt. % of a diluent, based on the total weight of the diesel additive. The diesel additive provided by the present invention can be used to remove carbon deposits at the nozzle of a diesel engine.

1 . A diesel additive, comprising:
 80-100 wt. % of a nonylphenol polyether amine; and   0-20 wt. % of a diluent,   based on the total weight of the diesel additive.   
     
     
         2 . The diesel additive according to  claim 1 , wherein the nonylphenol polyether amine comprises the following general formula: 
       
         
           
           
               
               
           
         
         wherein, m=2, n=24-26, y=1-2. 
       
     
     
         3 . The diesel additive according to  claim 1 , wherein the nonylphenol polyether amine has a molecular weight of 1700-3500. 
     
     
         4 . The diesel additive according to  claim 1 , wherein the nonylphenol polyether amine is present at a level of 90-100 wt. %. 
     
     
         5 . The diesel additive according to  claim 1 , wherein the diluent comprises: at least one of a saturated straight-chain hydrocarbon solvent, a cycloalkanes solvent, and a mixed aromatic hydrocarbon agent. 
     
     
         6 . The diesel additive according to  claim 1 , wherein the diluent is present at a level of 0-20 wt. %. 
     
     
         7 . A method for preparing the diesel additive according to  claim 1 , comprising the step of mixing the ingredients of the diesel additive. 
     
     
         8 . A method for using the diesel additive according to  claim 1 , comprising the step of adding the diesel additive to diesel. 
     
     
         9 . The diesel additive according to  claim 5 , wherein the diluent is present at a level of 0-20 wt. %.
