<p>PURPOSE: An improvement method of oil is provided to improve oxidation stability of fuel by contacting the oil guided from vegetable or animal materials with an ion-exchange medium, and to reduce processing costs of the oil. CONSTITUTION: A fuel oil composition of which oxidation stability is improved includes fuel oil and one or more fuel additives. The fuel oil includes alkyl ester of fatty acid induced form vegetable or animal materials and petroleum - originated oil. The alkyl ester of fatty acid is processed to improve oxidation stability. A process includes a step for contacting ester with one or more ion-exchange materials.</p> |
