A method for recovering synthetic oils from a feed stream, the method comprising separating at least a portion of the non-synthetic oil constituents from a commingled stream to produce a partially purified synthetic oil stream and one or more contaminant streams. Extracting at least a portion of the synthetic oil from the partially purified synthetic oil stream to produce a synthetic oil stream and a second contaminant stream.

The present invention provides compositions and methods related to the production and use of enzymes suitable for reducing the amount of steryl glycosides or saturated monoacyl glycerols in a lipid mixture.

Methods and compositions for the production of dielectric fluids from lipids produced by microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a lipid pathway modification enzyme, a fatty acyl-ACP thioesterase, a desaturase, a fatty acyl-CoA/aldehyde reductase, and/or an acyl carrier protein are useful in manufacturing dielectric fluids.

Described herein is a polymerized biorenewable, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to 80 wt % oligomer content, a polydispersity index ranging from about 1.30 to about 2.20, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

Disclosed herein are rejuvenating compositions for asphalt applications. In one aspect, the rejuvenating composition comprises a polymerized oil having a polymeric distribution ranging from about 2 to about 80 wt % oligomer content and Hildebrand solubility ranging from about 6 to about 12. In another aspect, the rejuvenating composition comprises an oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C. In yet another aspect, the rejuvenating composition comprises a modified oil having a Hildebrand solubility ranging from about 6 to about 12 and a flash point ranging from about 100 C. to about 400 C.

Described herein is a polymerized biorenewable, petroleum based, previously modified, or functionalized oil, comprising a polymeric distribution having about 2 to about 80 wt % oligomer content, a polydispersity index ranging from about 1.0 to about 5.0, and sulfur content ranging from 0.001 wt % to about 8 wt %. Methods of manufacturing the polymerized oil as well as its incorporation into asphalt paving, roofing, and coating applications are also described.

The present invention describes a process for purifying biodiesel without using a filter aid, in which purification of the biodiesel takes place by a sequence of washing operations after the reaction section, with stirring that is sufficiently vigorous to assist in the transformation of the molecules of esterified steryl glycosides, in order to convert them to a chemical form that can be removed by the process.

The present invention relates to processes for extracting lipid from vegetative plant parts such as leaves, stems, roots and tubers, and for producing industrial products such as hydrocarbon products from the lipids. Preferred industrial products include alkyl esters which may be blended with petroleum based fuels.
