The present invention relates to a method for producing fatty acid alkyl esters as well as cellulosic simplified sugars, shortened protein polymers, amino acids, or combination thereof resulting from the simultaneous esterification and hydrolysis, alcoholysis, or both of algae and other oil containing materials containing free fatty acids (FFA), glycerides, or combination thereof as well as polysaccharides, cellulose, hemicellulose, lignocellulose, protein polymers, or combination thereof in presences of an alcohol and an acid catalyst.
대표청구항▼
1. A method for making fatty acid alkyl esters, the method comprising: (a) combining an unextracted feedstock with an alcohol in the presence of water, wherein the feedstock comprises free fatty acids, glycerides, at least 10 wt % cellulosic material based on the dry weight of the feedstock, and at
1. A method for making fatty acid alkyl esters, the method comprising: (a) combining an unextracted feedstock with an alcohol in the presence of water, wherein the feedstock comprises free fatty acids, glycerides, at least 10 wt % cellulosic material based on the dry weight of the feedstock, and at least 10 wt % proteins based on the dry weight of the feedstock and the water content of the combination of the feedstock and the alcohol is at least 10 wt % of the dry weight of the feedstock; and(b) reacting the feedstock and the alcohol in the presence of water at a temperature in the range of 240° C. to 300° C., and at a pressure of 1000 to 2800 psi to generate fatty acid alkyl esters, cleave the cellulosic material and the proteins. 2. The method of claim 1, further comprising adding a fatty acid alkyl ester to the combination of the feedstock, the alcohol, and the water in (a) before reacting. 3. The method of claim 1, further comprising separating the resulting fatty acid alkyl esters from the resulting cleaved cellulosic material. 4. The method of claim 3, further comprising fermenting the cleaved cellulosic material to produce ethanol. 5. The method according to claim 1, wherein said feedstock is algae, dried distillers grains (DDG), rice bran, jatropha seed, palm seed, vegetable oil seeds, eukaryota, protozoa, phytoplankton, cyanobacteria, bacteria, corn ethanol fermentation residuals, or a mixture thereof. 6. The method of claim 1, wherein the alcohol is methanol or ethanol. 7. The method of claim 1, wherein the alcohol is in an amount from 50 mol % to 600 mol % of the contained oil in the feedstock. 8. The method of claim 1, wherein the temperature is in the range of 240° C. to 270° C.
