Abstract
This invention permits biodiesel (Fatty Acid Methyl Esters—FAMES) fuel and/or fuel blends to be used in cold weather climates without crystallization/precipitation of solids which plug fuel lines. The high melting point components are removed by physical separation from the biodiesel. Crystallization or distillation are used to separate the high melting temperature components. The low melting temperature components are used for blending with petroleum diesel with reduced or no winterization; low melting temperature components are used as a biodiesel with reduced or no winterization; low melting temperature components are blended into aviation jet fuel; or low melting temperature components are used as aviation jet fuel. The high melting temperature components are blended with petroleum diesel for temperate and/or hot weather climates.

- Biodiesel is composed of fatty acid methyl esters (FAMEs) which are produced from the transesterificaiton of glycerides (tri, di and/or mono) using methanol or the esterification of free fatty acids using methanol. Glycerides and free fatty acids come from plant and animal oils/fats. The fatty acids attached to the glycerides and the free fatty acids typically range from four (4) to twenty-two (22) carbon atoms. Each fatty acid has from zero (0) to three (3) double bonds between carbon atoms. Therefore, the FAMEs produced from a specific plant or animal oil/fat is a mixture of different carbon lengths. The physical properties of a biodiesel from a specific plant or animal oil/fat is due to the mixture of FAMEs.
- Biodiesel is typically blended into petroleum diesel at rates of 2-20% by volume. The amount of biodiesel blended is limited, because the biodiesel increases the blended fuel cloud point temperature. This cloud point temperature is the temperature at which solids crystallize and precipitate resulting in pluggage of fuel lines. So, the higher biodiesel fuel blends result in higher cloud point temperatures.
- Individual FAMEs range from a melting temperature of 54 degrees centrigrade with a corresponding boiling point of 394 degrees centrigrade to a melting point of minus 57 degrees centrigrade with a corresponding boiling point of 366 degrees centrigrade.
- FAME components in biodiesel have large enough differences in melting and boiling points to separate them using crystallization or distillation. This would permit the production of customized biodiesel products to satisfy cold, temperate, and hot weather climates.
- Physical separation of FAMEs by melting and/or boiling temperature would allow the production of a biodiesel that meets cold weather climate requirement of typically minus 20 degrees centrigrade. In addition, FAMEs with a melting temperature of minus 20 to minus 57 degrees centrigrade can be produced which are suitable for blending into aviation jet fuel.
- Based on melting temperature, FAMEs can be cooled until the undesirable FAME components crystallize forming solids. Then the solids can be batch/continuous separated by centrifugation or vacuum filtration.
- Based on boiling temperature, FAMEs can be distilled to separate low boiling from high boiling components. The low boiling components are also the low melting temperature components.
- I have discovered a method to produce a biodiesel (FAMEs) with lower melting temperatures than the biodiesel currently produced. This is achievable through separation of component FAMEs based on melting and/or boiling points.
- The low melting/boiling temperature biodiesel (FAMEs) produced by this invention can be used to blend into petroleum diesel with reduced or no need for winterizing additives, used as cold climate biodiesel with reduced or no winterization, or blended with aviation jet fuel. A limited production of biodiesel could be used to replace aviation jet fuel when the FAME melting point is low enough.
- The high melting/boiling temperature biodiesel (FAMEs) by-products produced by this invention can be used to blend into petroleum diesel for temperate or hot climates.
