NOVELTY - A vegetable oil or animal fats and oils is pre-processed (A) and liquefied, the saturated fatty acid is converted into unsaturated fatty acid by supplying and oxidizing ozone gas. The unsaturated fatty acid is primary-treated (B), and vacuum-distilled. The saturated fatty acid is secondary-treated (C), and converted into unsaturated fatty acid. The secondary-treated unsaturated fatty acid is tertiary-treated (D), and vacuum distilled. The residual liquor is filter-processed (E). Thus, fuel-formation purification of vegetable oil and animal fats and oils is carried out.    USE - For fuel-formation purification of vegetable oil and animal fats and oils.    ADVANTAGE - The vegetable oil and animal fats and oils are purified eco-friendly.    DETAILED DESCRIPTION - A vegetable oil or animal fats and oils is pre-processed (A) by heating at predetermined temperature and liquefied, the saturated fatty acid which does not burn easily is converted into unsaturated fatty acid which burns easily by supplying and oxidizing ozone gas. Further, the nitrogen gas is supplied and reduced. The polymerization is prevented. The unsaturated fatty acid is primary-treated (B), and vacuum-distilled. Then, the unnecessary substances such as paraffin, gelatin or protein are removed, to obtain primary products. The saturated fatty acid is secondary-treated (C), and the saturated fatty acid is converted into unsaturated fatty acid by supplying and oxidizing ozone gas to the residual liquor. Further, the nitrogen gas is supplied and oxidation is reduced. The unsaturated fatty acid obtained form secondary-treatment process is tertiary-treated (D), and vacuum distilled. Then, the unnecessary substances such as paraffin, gelatin or protein are removed, to obtain secondary product. The residual liquor containing paraffin in the solid which remained as a raw material of candle is filter-processed, and the filtered liquid is set as third order product. Thus, fuel-formation purification of vegetable oil and animal fats and oils is carried out. INDEPENDENT CLAIMS are included for the following:    (1) fuel-formation refiner of vegetable oil and animal fats and oils; and    (2) fuel-formation apparatus.
