    • A method for producing biofuels along with valuable food and neutraceutical products is provided. A method of making biofuels includes dewatering substantially intact algal cells to make an algal biomass, extracting neutral lipids along with carotenoids and chlorophylls from the algal biomass, and separation of the carotenoids and chlorophylls using adsorption or membrane diafiltration or other methods. The remaining neutral lipids are esterified with a catalyst in the presence of an alcohol. The method also includes separating a water soluble fraction comprising glycerin from a water insoluble fraction comprising fuel esters and distilling the fuel esters under vacuum to obtain a C 16 or shorter fuel esters fraction, a C16 or longer fuel ester fraction, and a residue comprising omega-3 fatty acids esters and remaining carotenoids. The method further includes hydrogenating and deoxygenating at least one of (i) the C16 or shorter fuel esters to obtain a jet fuel blend stock and (ii) the C16 or longer fuel esters to obtain a diesel blend stock.
    • 提供了生产生物燃料的方法以及有价值的食品和药物产品。 制造生物燃料的方法包括使基本上完整的藻细胞脱水以制备藻类生物质,从藻类生物质中提取中性脂质以及类胡萝卜素和叶绿素,以及使用吸附或膜渗滤或其它方法分离类胡萝卜素和叶绿素。 剩余的中性脂质在醇存在下用催化剂酯化。 该方法还包括从包含燃料酯的水不溶性级分中分离包含甘油的水溶性级分,并在真空下蒸馏燃料酯以获得C 16或更短的燃料酯馏分,C16或更长的燃料酯馏分,以及包含ω -3脂肪酸酯和剩余的类胡萝卜素。 该方法还包括将(i)C16或更短的燃料酯中的至少一种氢化和脱氧以获得喷气燃料共混料和(ii)C16或更长的燃料酯以获得柴油混合原料。

    • A method for producing biofuels is provided. A method of making biofuels includes dewatering substantially intact algal cells to make an algal biomass, sequentially adding solvent sets to the algal biomass, and sequentially separating solid biomass fractions from liquid fractions to arrive at a liquid fraction comprising neutral lipids. The method also includes esterifying the neutral lipids, separating a water miscible fraction comprising glycerin from a water immiscible fraction comprising fuel esters, carotenoids, and omega-3 fatty acids. The method also includes obtaining a C 16 or shorter fuel esters fraction, a C 16 or longer fuel ester fraction, and a residue comprising carotenoids and omega-3 fatty acids. The method includes hydrogenating and deoxygenating at least one of (i) the C16 or shorter fuel esters to obtain a jet fuel blend stock and (ii) the C16 or longer fuel esters to obtain a diesel blend stock.
    • 提供生产生物燃料的方法。 制备生物燃料的方法包括使基本上完整的藻细胞脱水以制备藻类生物质,依次向藻类生物质中加入溶剂组,以及从液体馏分中依次分离固体生物质馏分以获得包含中性脂质的液体级分。 该方法还包括酯化中性脂质,从包含燃料酯,类胡萝卜素和ω-3脂肪酸的水不混溶部分中分离包含甘油的水混溶级分。 该方法还包括获得C 16或更短的燃料酯馏分,C 16或更长的燃料酯馏分和包含类胡萝卜素和ω-3脂肪酸的残余物。 该方法包括将(i)C16或更短的燃料酯中的至少一种氢化和脱氧以获得喷气燃料共混料和(ii)C16或更长的燃料酯以获得柴油混合原料。
