The invention relates to a method for preparing an ethanol fuel composition, comprising the following steps: a) providing a first amount of ethanol to a vessel b) addition of an amount of ethoxylated oleyl amine and an amount of ignition improver to the ethanol provided in step a) such that a first mixture is obtained wherein: the concentration of ethanol in the first mixture is 35-55 % (w/w); the ratio (w/w) of ethoxylated oleyl amine to ethanol in the first mixture is in the range 1:4 – 1:15, preferably in the range 1:6 – 1:10, and the ratio (w/w) of ignition improver to ethanol in the first mixture is in the range 1:1 – 1:3, preferably in the range 1:1.2 – 1:2 c) blending the first mixture by using vertical circulation and/or stirring such that a blended first mixture is obtained; d) combining the blended first mixture obtained in step c) with a second amount of ethanol such that a second mixture is obtained; e) blending of the second mixture obtained in step d) to obtain the ethanol fuel wherein the ethanol fuel obtained in step e) comprises: 20 80-90 % (w/w), preferably 84-88 % (w/w) ethanol 0.1-2 % (w/w), preferably 0.5-1.5 % (w/w) ethoxylated oleyl amine 3-10 % (w/w), preferably 4-6 % (w/w) ignitionimprover and wherein the ignition improver added in step b) is a water soluble adduct of 25 polyol having 3-10 hydroxyl groups and ethylene oxide and/or propylene oxide and wherein the molecular weight of the aduct is 350 to 2000 Da, preferably 600-1000 Da; |
