Abstract

The present invention teaches an ethanol modifier and a clean ethanol fuel comprising the modifier. The ethanol modifier comprises the following components in stated weight percentages: sugar remover 12-17%; emulsifier 2-5%; antioxidant 2-6%; preservative 2-6%; antiaging agent 3-8%; cleaning agent 1-3%; anti-wearing agent 7-10%; combustion promoter 12-15%; octane enhancing additive 22-28%; and compatibilizer 18-30%. All of the components are commercially-available and readily prepared. The clean ethanol fuel comprising the ethanol modifier of the present invention is better than the national 93 octane gasoline standard, and can satisfy the European IV discharge standard.

         7 . A method for preparation of said ethanol modifier of  claim 1 , comprising the steps of: 
 adding firstly said compatibilizer proportionally into a mixing plant;    adding solids, such as the antioxidant and the preservative, and the thick component into the mixing plant;    mixing the added components at a speed of 80-1000 revolutions per minute to form a uniform liquid solutions;    adding remaining components into the mixing plant; and    mixing the components at a speed of 200-1000 revolutions per minute until the components are uniformly distributed.    
     
     
         8 . A method for preparation of said ethanol modifier of  claim 2 , comprising the steps of: 
 adding firstly said compatibilizer proportionally into a mixing plant;    adding solids, such as the antioxidant and the preservative, and the thick component into the mixing plant;    mixing the added components at a speed of 80-1000 revolutions per minute to form a uniform liquid solutions;    adding remaining components into the mixing plant; and    mixing the components at a speed of 200-1000 revolutions per minute until the components are uniformly distributed.    
     
     
         9 . A method for preparation of said ethanol modifier of  claim 3 , comprising the steps of: 
 adding firstly said compatibilizer proportionally into a mixing plant;    adding solids, such as the antioxidant and the preservative, and the thick component into the mixing plant;    mixing the added components at a speed of 80-1000 revolutions per minute to form a uniform liquid solutions;    adding remaining components into the mixing plant; and    mixing the components at a speed of 200-1000 revolutions per minute until the components are uniformly distributed.
