Definitions

  • the invention is directed to methods, apparatus, and/or feedstock suitable for use in biofuels production, as well as biofuel compositions resulting from the biofuels production.
  • Natural oils derived from oil-accumulating organisms have been employed as foodstuffs, in health and nutrition, as lubricants, and also as fuels. Natural oils have many sources, such as from oil-producing seed crops (for example, soya, rapeseed, jatropha), byproducts of animal processing (for example, lard and tallow), photosynthetic microorganisms (for example, algae, microalgae, cyanobacteria), and heterotrophic microorganisms (for example, yeast, fungi, molds).
  • the wide range of sources naturally imparts a wide variety of product compositions and characteristics including, for example, fatty acid saturation level, chain length, and impurities. These multiple sources of natural oils can be further expanded through the application of genetic engineering for the refinement of product characteristics.
  • rapeseed oil In fuel applications, an important derivative of natural oils is from transesterification of glycerides. As a result of their prevalence as foodstuffs, natural oil-seeds and their compositions have become industry standard. For instance, the compositional profile of rapeseed oil is seen as the accepted standard for bio-derived FAME (fatty acid methyl ester). The fatty acid profile of rapeseed oil is one that is enriched in 18-carbon fatty acids, and especially unsaturated acids. The table below shows the breakdown of fatty acid as x:y, wherein x is the number of carbons and y is the number of unsaturated bonds in the carbon chain.
  • bio-diesel fuels made from oils of these compositions have certain drawbacks as diesel fuels.
  • the pour point of rapeseed bio-diesel is relatively high (-7 to -4°C), and the unsaturated bonds are subject to oxidative degradation, limiting shelf-life.
  • the density of rapeseed bio-diesel is relatively high and the cetane is consistent with finished petroleum diesel, limiting the ability to extend diesel supply by blending of lower quality, heavy materials (for example, aromatics).
  • Rapeseed oils could also be hydrotreated, whereby the glycerides are converted to paraffins, such as by:
  • the invention is directed to methods, apparatus, and/or feedstock suitable for use in biofuels production, as well as biofuel compositions resulting from the biofuels production.
  • the resulting biofuels have improved cold flow properties. Additionally, the methods of the invention are efficient, without requiring further processing such as isomerization.
  • the invention is directed to a feedstock suitable for biofuels production.
  • the feedstock comprises glycerides derived from an oleaginous (oil-accumulating) microorganism having at least about 10% by weight of fatty acid chains of length C16 or lower, and an iodine value of about 100 grams of iodine consumed per 100 gram sample of feedstock, or less.
  • the biofuel resulting from the methods, apparatus, and/or feedstock described herein has a cold-flow pour point of about 20° C or lower.
  • the resulting biofuel has a density below about 940 kg/m 3 at 15° C. According to some embodiments, the resulting biofuel has a cetane value of at least about 50.
  • the resulting biofuel has an isomerization ratio of less than 2.
  • the resulting biofuel includes a fuel made by a hydrotreating process.
  • the resulting biofuel includes diesel, jet fuel, and/or a blend of any combination of diesel, jet fuel, other biofuels or petroleum.
  • the resulting biofuel may be either a fuel or a fuel additive.
  • the oleaginous microorganism from which the glycerides are derived includes algae, fungi, bacteria, and/or cyanobacteria. More particularly, in certain embodiments, the oleaginous microorganism includes Saccharomyces unisporus, Saccharomyces dairensis, Aspergillus nidulans, Sprilulina maxima, Entomorphtoria coronata, Entomorphtoria obscura, Cyclotella cryptica, Navicula muralis, Phaeodactylum triconutum, Thalassiosira pseudonana, or combinations thereof.
  • the glycerides include at least about 10% by weight of fatty acid chains of length C14 or lower. In certain embodiments, the glycerides include at least about 10% by weight of fatty acid chains of length C12 or lower.
  • the glycerides do not undergo isomerization, or hydroisomerization, or catalytic isomerization, or at least a significant amount of the glycerides do not undergo any type of isomerization.
  • the invention is directed to a method of producing a biofuel.
  • the method includes hydroprocessing glycerides derived from an oleaginous microorganism and composed of at least 10% by weight of fatty acid chains of length C16 or lower.
  • the method produces a biofuel having a cold-flow pour point of about 20° C or lower.
  • the method is carried out without the glycerides undergoing isomerization, or hydroisomerization, or catalytic isomerization, or at least without a significant amount of the glycerides undergoing any type of isomerization.
  • the method further includes blending a quantity of the biofuel with a fossil-derived fuel.
  • the invention is directed to a biorefinery for producing a feedstock suitable for biofuels production.
  • the biorefinery includes a hydroprocessing unit for hydroprocessing glycerides derived from an oleaginous microorganism and composed of at least 10% by weight of fatty acid chains of length C16 or lower.
  • the biorefinery does not include any units designed for carrying out isomerization, or hydroisomerization, or catalytic isomerization.
  • the FIGURE schematically shows an apparatus within a biorefinery, according to some embodiments.
  • the invention is directed to methods, apparatus, and/or feedstock suitable for use in biofuels production, as well as biofuel compositions resulting from the biofuels production.
  • natural oil compositions can be produced that allow for renewable production of diesel molecules having improved cold flow properties.
  • alternative glyceride compositions are used to provide an improved hydrotreating feedstock and final biofuel product. More particularly, through careful selection of the source organism and/or genetic engineering glyceride chain lengths and saturation levels as described herein can result in high-yield hydroprocessing and generation of a quality diesel fuel. Additionally, the methods of the invention are efficient, without requiring further processing such as isomerization.
  • the invention includes a renewably- derived feedstock suitable for biofuels production.
  • the feedstock may include glycerides derived from an oleaginous microorganism.

  • the oleaginous microorganism is genetically modified. More particularly, in certain embodiments, the microorganism may include genetically modified Escherichia coli or Saccharomyces cerevisiae.
  • the glycerides may include at least about 10% by weight of fatty acid chains of length C16 or lower. In some embodiments, the glycerides may include at least about 10% by weight of fatty acid chains of length C14 or lower. In some embodiments, the glycerides may include at least about 10% by weight of fatty acid chains of length C12 or lower. In contrast to glycerides having long chain lengths, such as C18, the shorter chain lengths of the glycerides herein can be hydrotreated without requiring further processing, such as isomerization or hydroisomerization, in order to improve the cold flow properties of a resulting biofuel product.
  • the amount of fatty acid chains of a specific length or lower may be between about 10 percent and about 95 percent, between about 20 percent and about 80 percent, at least about 20 percent, at least about 30 percent, at least about 40 percent, and/or the like.
  • the feedstock may have a density below about 940 kg/m 3 at 15° C. In some embodiments, the feedstock may have a density between about 830 kg/m 3 and about 930 kg/m 3 , or between about 840 kg/m 3 and about 920 kg/m 3 at 15° C. Since fuel is sold by volume, not density, the relatively low density of the feedstock increases the efficiency of producing the resulting biofuel.
  • Iodine values are indicative of the overall degree of unsaturation of a fatty acid. Unsaturated bonds are subject to oxidative degradation, which limits shelf-life of a resulting product. According to some embodiments, the feedstock has an iodine value of about 100 or less, or between about 0 and about 50, or between about 0 and about 25 grams of iodine consumed per 100 gram sample.
  • the table below provides iodine value estimates for the same organisms listed in the preceding tables. The iodine value estimates are based on mono, di, and tri unsaturated contents and correlations with known compositions' iodine values.
  • Thalassiosira Pseudon. 3H 49 A higher saturation level, such as in the predominantly saturated and mono-unsaturated fatty acids shown in the table above, minimizes the fouling potential as well as the amount of hydrogen consumed and heat released by catalytic reduction to paraffins.
  • the table below illustrates the reaction yields and heat effects for model lipids undergoing typical 50% hydrogenation and 50% decarboxylation reaction pathways (with 100% conversion and 50% subsequent methanation of C0 2 ).

  • GAS YIELDS Nm tri-acyl glyceride
  • Heat of Reaction -746 -990 -1 166 -2012 -1015 -131 1 kJ/kg TAG A relatively higher level of shorter-chain fatty acids (e.g., ⁇ C12, C14, C16) increases product quality (e.g., cold flow properties) and reduces heat evolution at the expense of a small amount of additional H 2 consumption.
  • the resulting biofuel may have a pour point of about 20° C or lower, or about 15° C or lower, or about 10° C or lower. According to some embodiments, the resulting biofuel may have a cetane value of at least about 50, or at least about 60, or at least about 70. According to some embodiments, an isomerization ratio of the resulting biofuel may be less than about 2, or between about 1 and about 2, or between about 0 and about 1 .
