Benefits of technology

[0012]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 lim

Problems solved by technology

A limited production of biodiesel could be used to replace aviation jet fuel when the FAME melting point is low enough.

Embodiment Construction

[0015]The process described herein is not feedstock limited and is capable of processing different biodiesel feedstocks simultaneously or by campaigning. Inexpensive biodiesel feedstocks can be processed to maximize the value added by this process. So, an expensive oil that naturally has a mix of fatty acids which produce a lower cloud point temperature does not have to be used to produce a biodiesel for cold weather climates.

[0016]Biodiesel is typically blended into petroleum diesel at rates of 2-20% by volume. The amount of biodiesel blended is limited, because the biodiesel reduces the blended cloud point temperature. This cloud point temperature is the temperature at which solids crystallize and precipitate resulting in pluggage of fuel lines.

[0017]Melting and boiling temperature physical properties of various oils / fats can be found in the following;

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not ApplicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableREFERENCE TO SEQUENCE LISTING, A TABLE, OR A COMPUTER PROGRAM LISTING COMPACT DISC APPENDIX[0003]Not ApplicableBACKGROUND OF INVENTION[0004]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 F...
