Zusammenfassung:	A method of manufacturing biodiesel is provided. The method of manufacturing biodiesel includes the following steps: providing vegetable oil, a metal catalyst, and alcohol in a reactor; phase-changing the alcohol to supercritical alcohol; performing a transesterification reaction between the vegetable oil and the supercritical alcohol to obtain an unsaturated fatty acid; and performing a hydrogenation reaction by adding hydrogen to the unsaturated fatty acid ester using the metal catalyst. The transesterification reaction and the hydrogenation reaction may be performed simultaneously. 바이오디젤의 제조 방법이 제공된다. 상기 바이오디젤의 제조 방법은, 반응기 내에 식물유, 금속 촉매, 및 알코올을 제공하는 단계, 상기 알코올을 초임계 알코올로 상전이시키는 단계, 상기 식물유와 상기 초임계 알코올에 대하여 에스테르교환 반응을 수행하여 불포화 지방산 에스테르를 형성하는 단계, 및 상기 금속 촉매를 이용하여 상기 불포화 지방산 에스테르에 수소를 첨가하는 수소첨가 반응을 수행하는 단계를 포함한다. 상기 에스테르교환 반응과 상기 수소첨가 반응은 동시에 수행될 수 있다.
