摘要:
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.

摘要:
The present invention relates to a method for reactively crushing jatropha seeds, said method making it possible, starting with specifically conditioned jatropha seeds in the presence of light alcohol and a basic catalyst, to carry out, in a single step, the crushing as well as the reaction for transesterifying the triglycerides present in the jatropha oil, thus causing an oil cake, glycerol, and fatty acid esters to be simultaneously produced. The method for processing the jatropha seeds, according to the invention, makes it possible to inactivate, in a simple, low-cost manner, the phorbol esters in addition to the curcine, thus enabling humans to handle the seeds without risk and moreover use the castor oil cake in animal feed. Characteristically, the seeds are conditioned by a series of operations that include a step of pressing the seeds and a step of drying same.

The invention discloses a new solvent-free process for obtaining phospholipids and neutral lipids enriched krill oils containing DHA and EPA poly-unsaturated fatty acids and astaxanthin. The process includes cooking fresh krill at high temperature -without agitation and or grinding; decanting the cooked krill for obtaining a partial de-fatted and de-watered solid and a liquid; squeezing the obtained solid to obtain a press liquid and a solid fraction; centrifuging the press liquid to obtain the phospholipids enriched krill oil; centrifuging of the decanter liquid obtained to obtain the neutral lipid enriched krill oil and stickwater.
摘要:
The present invention relates to a novel method for separating an edible oil, such as extra virgin olive oil, into useful fractions. In one embodiment the triglycerides are separated as a fraction and the remaining fractions recombined to form an olive oil with little or no triglycerides.
摘要:
A process for the handling and storage of marine oils comprising the steps of: (a) optionally heating the marine oil to a temperature of 20-45 C to ensure that the marine oil is fully liquid; (b) Cooling the fully liquid marine oil in one or more scraped surface heat exchangers to a temperature of -5-10 C; (c) maintaining the cooled marine oil obtained in step (b) in one or more a steered vessels at a temperature of -5-10 C for a total period of 1-10 minutes; (d) Storing the marine oil thus obtained in a closed container at a temperature below 15 C.
摘要:
A method for separating neutral and polar lipids from an oil of biological material, wherein the oil is fractionated using a mixture of a polar solvent comprising at least one carbon atom, water and an additional substance selected from the group consisting of: mono-, di- and oligosaccharides comprising from 3 to 10 monosaccharide units, said additional substance is present in an amount of at least 0,1 wt% calculated on the total weight of solvent, water and additional substance, to form at least two liquid fractions having different densities, wherein one fraction is rich in polar lipids and another fraction is rich in neutral lipids. An oil rich in polar lipids obtained from the method is disclosed, said oil I contains at least 40, preferably at least 50 lipid% polar lipids as calculated on the total amount of lipids in said oil and that the total amount of polar solvent and water in said oil is between 20 and 30 wt%. An oat oil containing high amounts of estolides of DGDG can further be obtained.
摘要:
The present invention relates to a continuous process for isolation of oils from a micro organism slurry or an algae slurry comprising feeding the slurry into a three phase centrifugal separator having a stack of separating discs and operating under force of at least 4500 G, preferably under a force of at least 5000 G, obtaining three phases: one oil phase, one liquid phase and one bio-organic phase. The present invention relates also to use of the process for production of bio-diesel or bio-fuels.
