Fuel production from feedstock containing lipidic material

Abstract

This invention relates to the production of dewaxed and/or hydroisomerized fuel composition that includes a step of hydrotreating a feedstock containing the lipidic material. The fuel compositions are high quality fuel compositions in which the fuel can be ultimately tailored for a variety of end uses such as jet fuel or diesel fuel.

1 . A method for producing a dewaxed fuel composition comprising:
 providing a feedstock containing lipidic biomass;   hydrotreating the feedstock to produce a hydrotreated material; and   dewaxing at least a portion of the hydrotreated material to produce the dewaxed fuel composition.   
     
     
         2 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as jet fuel or diesel fuel. 
     
     
         3 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as jet fuel having a smoke point of at least 25.0 mm. 
     
     
         4 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as jet fuel having a freeze point of not higher than −35° C. 
     
     
         5 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as jet fuel having an ASTM D86 90% distillation point within the range of from 250° C. to 290° C. 
     
     
         6 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as jet fuel having an ASTM D86 90% distillation point within the range of from 200° C. to 240° C. 
     
     
         7 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is recovered as diesel fuel having an ASTM D86 90% distillation point within the range of from 260° C. to 350° C. 
     
     
         8 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is distilled and at least one jet fuel or at least one diesel fuel is recovered following distillation. 
     
     
         9 . The method of  claim 1 , wherein at least a portion of the dewaxed fuel composition is hydroisomerized to produce a hydroisomerized composition and at least a portion of the hydroisomerized composition is recovered as jet fuel or diesel fuel. 
     
     
         10 . The method of  claim 1 , wherein the feedstock further comprises mineral oil. 
     
     
         11 . A method for producing a hydroisomerized fuel composition comprising:
 providing a feedstock containing lipidic biomass;   hydrotreating the feedstock to produce a hydrotreated material; and   hydroisomerizing at least a portion of the hydrotreated material to produce the hydroisomerized fuel composition.   
     
     
         12 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as jet fuel or diesel fuel. 
     
     
         13 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as jet fuel having a smoke point of at least 25.0 mm. 
     
     
         14 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as jet fuel having a freeze point of not higher than −35° C. 
     
     
         15 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as jet fuel having an ASTM D86 90% distillation point within the range of from 250° C. to 290° C. 
     
     
         16 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as jet fuel having an ASTM D86 90% distillation point within the range of from 200° C. to 240° C. 
     
     
         17 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is recovered as diesel fuel having an ASTM D86 90% distillation point within the range of from 260° C. to 350° C. 
     
     
         18 . The method of  claim 11 , wherein at least a portion of the hydroisomerized fuel composition is distilled and at least one jet fuel or at least one diesel fuel is recovered following distillation. 
     
     
         19 . The method of  claim 11 , wherein the feedstock further comprises mineral oil. 
     
     
         20 . A method for producing a hydroisomerized fuel composition comprising:
 providing a feedstock containing lipidic biomass;   hydrotreating the feedstock to produce a hydrotreated material;   dewaxing at least a portion of the hydrotreated material to produce a dewaxed fuel composition; and   hydroisomerizing at least a portion of the dewaxed fuel composition to produce the hydroisomerized fuel composition.
