  • Patent number: 9028697
    Abstract: The moisture absorption capacity of biofuels can be more or less 10 times that of fossil diesel oil, causing biofuels to form acids that induce metal corrosion and form deposits in the fuel tank and pipe lines. Methods for removing moisture from stored biofuels and plant oils are described wherein glycerol is used as a solvent to extract the moisture from the bioliquid or oil, comprising the steps of placing the biofuel or oil in fluid contact with glycerol, incubating for a time, and then removing the glycerol. A cellulous ester dialysis or other semi-permeable membrane may be used to prevent the glycerol from contaminating the biofuel while allowing moisture to pass. Crude glycerol produced as a byproduct of biodiesel production may be used in the method of the disclosed invention with good result. Preferred embodiments of apparatus that employ the method of the subject invention are described.

    Abstract: A system and process are described for clean separation of biocrudes and water by-products from hydrothermal liquefaction (HTL) product mixtures of organic and biomass-containing feedstocks at elevated temperatures and pressures. Inorganic compound solids are removed prior to separation of biocrude and water by-product fractions to minimize formation of emulsions that impede separation. Separation may be performed at higher temperatures that reduce heat loss and need to cool product mixtures to ambient. The present invention thus achieves separation efficiencies not achieved in conventional HTL processing.

  • Publication number: 20140316151
    Abstract: An improved pasteurisation protocol for pasteurising microbial cells is disclosed. The protocol has three stages, a first heating stage, a second plateau stage at which the cells are held at a (maximum and) constant temperature, and a third cooling stage. Both the heating and the cooling stages are rapid, with the temperature of the cells passing through 40 to 80° C. in no more than 30 minutes in the heating stage. The heating rate is at least 0.5° C./minute and during cooling is at least ?0.5° C./minute. The plateau maximum temperature is from 70 to 85° C. By plotting the pasteurisation protocol on a time (t, minutes) versus temperature (T, ° C.) graph, one obtains a trapezium having an area less than 13,000° C. minute. Not only does this result in a smaller energy input (and so a reduction in costs), but a better quality (and less oxidised) oil results having a peroxide value (POV) of less than 1.5 and an anisidine value (AnV) of less than 1.0.

  • Patent number: 8715980
    Abstract: Described are methods of cultivating autotrophic microorganisms, particularly microalgae or diatoms, in a bioreactor by entraining a culture of the microorganisms in a tenuous, gelated, thixotrophic carrier medium having nutrients therefor and moving the medium along a passage at a sufficiently slow speed to enable laminar flow which in cross section is closed and which has transparent walls through which the culture is irradiated to enable photosynthesis. The method includes effecting convective turnover of the culture and medium as they flow along the passage by differentially heating the medium laterally relative to the flow direction so as to produce a generally helical flow of the culture and medium. Also described are processing methods, both physical and chemical, performed underground e.g.

  • Patent number: 8709109
    Abstract: A process for preparing biodiesel having improved filterability characteristics including inducing transesterification of a triglyceride feedstock with cavitation to form an intermediate reaction product. Glycerol by product is separated from the intermediate reaction product before finishing the transesterification reaction in a pressurized reaction tank to yield a biodiesel reaction product. The biodiesel reaction product can be further purified by removing glycerol.

  • Patent number: 8680305
    Abstract: A method of obtaining a polyunsaturated fatty acid derivative comprises contacting a mixture of fatty acid derivatives with a silver salt aqueous solution, and adjusting the free fatty acid content in the silver salt aqueous solution to 0.2 meq or less per gram of silver when repeatedly using the silver salt aqueous solution. A polyunsaturated fatty acid derivative having high purity and excellent quality can thus be economically obtained.

  • Publication number: 20140073038
    Abstract: In one aspect of the invention, a method recovers oil from a concentrated byproduct, such as evaporated thin stillage formed during a dry milling process used for producing ethanol. The method includes forming a concentrate from the byproduct and recovering oil from the concentrate. The step of forming the concentrate may comprise evaporating the byproduct. Further, the step of separating the oil from the concentrate may comprise using a centrifuge and, in particular, a disk stack centrifuge. Other aspects of the invention include related methods and subsystems for recovering oil from thin stillage.
