The disclosure relates to a magnesium salt of one or more polyunsaturated fatty acids (PUFAs), a process for preparing same and a composition comprising said magnesium salt of one or more PUFAs and at least one stability enhancer.

The invention relates to a method for producing an oil rich fraction (OF) from primary feedstock (FS) that comprises water, first salt, second salt, and biomass. The feedstock (FS) is provided to a first reaction zone (Z1) of a conversion reactor (100), where it is allowed to react at a temperature of at least 350° C. in a pressure of at least 160 bar to form converted primary feedstock. The method comprises separating from the converted primary feedstock a first salt rich fraction (SF1), a second salt rich fraction (SF2), and an oil rich fraction (OF). The method comprises withdrawing the oil rich fraction (OF) from the first reaction zone (Z1) and withdrawing the first salt rich fraction (SF1) and the second salt rich fraction (SF2) from the conversion reactor (100). In the method the first salt rich fraction (SF1) comprises at least some of the first salt dissolved in the water, the second salt rich fraction (SF2) comprises at least some of the second salt in solid form, and at least one of the first salt and the second salt is a salt capable of catalysing the reaction of the biomass of the primary feedstock (FS) with the water of the primary feedstock (FS) to produce the oil rich fraction (OF). A device for the same.

Aspects of the present invention provide methods of drying lecithin in a batch reaction, comprising the steps of obtaining a lecithin-containing material (derived from a crude refining stream) comprising 15-50% water, 10-30% acetone insoluble matter, and 10-20% free fatty acid; adding a fatty acid source (also derived from a crude refining stream) to the lecithin-containing material composition to obtain a lecithin/fatty acid reaction mixture; and blowing dry gas through the gum/fatty acid reaction mixture to obtain a resultant dried lecithin fatty acid blend having a water content of less than 2%. The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.

A microorganism oil composition, in particular of microalgae, enriched with polyunsaturated fatty acids, characterised in that it has a saturated fatty acid content of less than or equal to 40 mg/g of composition, an omega-3 polyunsaturated fatty acid content greater than or equal to 500 mg/g of composition, and in that it includes, with respect to the total quantity of monoglycerides, diglycerides, triglycerides and fatty acid ethyl esters, a quantity of triglycerides below 70%, a quantity of diglycerides of between 10 and 35%, and a quantity of monoglycerides of between 1 and 5%.

Disclosed is a method of producing an estolide having high structural stability, including: a) preparing a fatty acid mixture from biomass-derived oil; b) separating the fatty acid mixture into a C16 fatty acid and a C18 fatty acid; c) converting the C18 fatty acid into a C18 or C17 linear internal olefin; and d) subjecting the C18 or C17 linear internal olefin and the C16 fatty acid to an estolide reaction, thus obtaining an estolide.

Metathesized triacylglycerol polyols, fractionated polyol variants thereof, and their related physical and thermal properties are disclosed.

The present invention discloses a method for recycling urea in the process of separating and purifying unsaturated substances through a urea adduction method. The method comprises the following steps: liposoluble substances containing target unsaturated components are used as raw materials, and subjected to urea adduction, crystallization and filtration to produce a filtrate, from which the specific unsaturated components are obtained; the urea adduct is dissolved in a polar solvent, and after the adducted adducts are layered and released, adding a certain solvent to the urea solution to adjust the polarity, then cooling for crystallization, and recycling the urea. The method can realize complete release of the adducted components and recycling and reuse of urea, and the process is simple, the recovery rate is high, and the adduction effect is not influenced when recycling urea for reuse, and the production cost of the urea adduct is reduced, thus alleviating the adverse impact of urea discharges on the environment.

The resultant dried lecithin fatty acid blend may be used in asphalt or oil field applications.

One or more techniques are disclosed for a process of preparing stearic acid from animal and/or plant sources may comprise: 1) deodorizing and distilling a fat; 2) concentrating fatty acids of the fat; and 3) hydrogenating the fatty acid to provide stearic acid. The process may include the use of co-products from plant and/or animal sources. The process may also include distilling the stearic acid to provide palmitic acid and/or fully hydrogenated fatty acid. Tallow fatty acid, vegetable fatty acid, stearic acid, and palmitic acid prepared from the process described are also disclosed.

The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.
