METHOD FOR SIMULTANEOUSLY PRODUCING BIODIESEL, BIODIESEL ADDITIVE, AND ALKYL FORMATE FROM MICROALGAE

The present invention relates to a method for simultaneously producing, from microalgae, a biodiesel, and at least one compound selected from the group consisting of an alkyl levulinate, an alkyl formate, and a dialkyl ether. According to the present invention, the alkyl levulinate, the alkyl formate, and the dialkyl ether, which are high value added compounds, can be produced using the cellulose portion of the microalgae which was wasted during the production of biodiesel using microalgae in the past. La présente invention concerne un procédé permettant de produire simultanément, à partir de microalgues, un biodiesel, et au moins un composé choisi dans le groupe constitué par un lévulinate d'alkyle, un formiate d'alkyle, et un éther de dialkyle. Selon la présente invention, le lévulinate d'alkyle, le formiate d'alkyle et l'éther de dialkyle, qui sont des composés à forte valeur ajoutée, peuvent être produits à l'aide de la partie cellulose des microalgues qui était perdue pendant la production de biodiesel en utilisant des microalgues dans l'état de la technique. 본 발명은 미세조류에서 알킬 레불리네이트(alkyl levulinate), 알킬 포메이트(alkyl formate) 및 다이알켈 에테르(dialkyl ether)로 구성된 군에서 선택되는 하나 이상의 화합물과 바이오디젤을 동시에 제조하는 방법에 관한 것이다. 본 발명에 따르면, 종래 미세조류를 이용한 바이오디젤 생산시에 버려졌던, 미세조류의 셀룰로오스 부분을 이용하여 고부가가치의 화합물인 알킬 레불리네이트(alkyl levulinate), 알킬 포메이트(alkyl formate), 다이알켈 에테르(dialkyl ether)를 생산할 수 있다.
