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.

Claims

exact text as granted — not AI-modified
1 . A separation process for biodiesel (Fatty Acid Methyl Esters—FAMEs) components which will control the cloud point temperature of the biodiesel product. 
   
   
       2 . The use of crystallization to separate FAMEs. 
   
   
       3 . The use of distillation to separate FAMEs. 
   
   
       4 . The production of a cold weather biodiesel for blending with petroleum diesel requiring reduced or no winterization. 
   
   
       5 . The production of a cold weather biodiesel requiring reduced or no winterization. 
   
   
       6 . The production of a cold weather biodiesel for blending with aviation jet fuel. 
   
   
       7 . The production of a cold weather biodiesel for use as an aviation jet fuel. 
   
   
       8 . The production of a temperate and/or hot weather biodiesel for blending with petroleum diesel. 
   
   
       9 . Processing of different biodiesel feedstocks simultaneously or by campaigning. 
   
   
       10 . Processing inexpensive biodiesel feedstocks to maximize the value added by this process.
