Diesel fuel composition

Abstract

Disclosed is a diesel fuel composition obtained by mixing a diesel oil and a biodiesel oil, which can be used in popular diesel cars. The diesel fuel composition enables remarkable reduction in sludge formation. Specifically disclosed is a diesel fuel composition obtained by mixing a diesel oil containing an aromatic component and a biodiesel oil. The diesel fuel composition is characterized in that the biodiesel oil content in the diesel fuel composition is 10-50% by volume, and the aromatic component content in the diesel oil is not less than 30% by volume.

1 . A diesel fuel composition made by mixing diesel fuel oil containing an aromatic component with biodiesel,
 wherein a content percentage of the biodiesel in the diesel fuel composition is 10% by volume to 50% by volume, and   wherein a content percentage of the aromatic component in the diesel fuel oil is at least 30% by volume.   
     
     
         2 . The diesel fuel composition according to  claim 1 , wherein the biodiesel is a biodiesel obtained by methyl esterification of vegetal oil having an iodine value of 50 to 200. 
     
     
         3 . The diesel fuel composition according to  claim 2 , wherein the vegetal oil is at least one selected from the group consisting of linseed oil, safflower oil, high oleic safflower oil, soybean oil, sesame oil, corn oil, rapeseed oil, cottonseed oil, olive oil, palm oil, sunflower oil, and Jatropha oil.
