Method for producing biodiesel from algal lipid with dimethyl carbonate

Abstract

The present invention relates to a method for renewable energy production using biomass, more specifically, method for producing eco-friendly biodiesel with algal lipid and dimethyl carbonate.

What is claimed is: 
     
         1 . A method for producing biodiesel from algal lipid with dimethyl carbonate. 
     
     
         2 . The method of  claim 1 , wherein the algal lipid is extracted from an algae with dimethyl carbonate. 
     
     
         3 . The method of  claim 1 , wherein the biodiesel is made by transesterification reaction of algal lipid and dimethyl carbonate. 
     
     
         4 . The method of  claim 2 , wherein the algae is cultured in wastewater. 
     
     
         5 . The method of  claim 2 , wherein the algae is selected from the genus  Ankistrodesmus , the genus  Scenedesmus , the genus  Chlorella , the genus  Anabaena , the genus  Oscillatoria , the genus  Botryococcus,  the genus  Neochloris , the genus  Tetraselmis , the genus  Porphyridium , the genus  Phaeodactylum , the genus  Nannochloropsis , the genus  Ellipsoidion , the genus  Isochrysis , the genus  Pavlova , the genus  Thalassiosira , the genus  Skeletonema , the genus  Chlorococcum , the genus  Dunaliella , the genus  Aphanizomenon , the genus  Haematococcus , the genus  Crypthecodinium  and the genus  Shizochytrium.    
     
     
         6 . The method of  claim 2 , wherein the algal lipid is extracted by the mixture ratio of algal biomass:dimethyl carbonate=1:20 (g/mL). 
     
     
         7 . A biodiesel without glycerol, produced according to the method of  claim 1 .
