Process to prepare jet fuels and its products

Abstract

A jet fuel containing a major amount of a synthetic paraffinic kerosene fuel component is provided by: a) providing a synthetic paraffinic kerosene fuel component in the jet boiling range having at least 99.5 wt % hydrocarbon, said hydrocarbon being at least 98.5 wt % paraffins, less than 1 wt % bicyclic compounds, and less than 0.5 wt % total aromatics as measured by ASTM D2425; b) providing a petroleum-based jet fuel component in the jet boiling range; c) providing pinane; and d) blending component a), b) and c), wherein component c) is present in an amount of 5 to 40 weight percent, based on the blend, and component a) and b) are in a ratio of greater than 1 to 1 thereby providing a jet fuel blend having a density of from 775 to 840 kg/m 3 .

         2 . The method of  claim 1  wherein component c) is present in an amount of 5 to 35 weight percent, based on the blend. 
     
     
         3 . The method of  claim 1  wherein the jet fuel blend has an aromatic content of less than 10 vol. % based on the jet fuel blend. 
     
     
         4 . The method of  claim 3  wherein the fuel blend has an aromatic content of less than 8 vol. % based on the jet fuel blend. 
     
     
         5 . The method of  claim 3  wherein component c) is present in an amount of 5 to 35 weight percent, based on the blend. 
     
     
         6 . The method of  claim 1  wherein component c) is present in an amount of 10 to 35 weight percent, based on the blend. 
     
     
         7 . The method of  claim 1  wherein component c) is present in an amount of 10 to 30 weight percent, based on the blend. 
     
     
         8 . A jet fuel composition having a density of from 775 to 840 kg/m 3  comprising:
 a) a petroleum-based jet fuel component other than b) boiling for more than 90 vol % at from 130 to 300° C.;   b) greater than 50 weight percent, based on combined components a) and b), of a synthetic paraffinic kerosene fuel component in the jet boiling range having at least 99.5 wt % hydrocarbon, said hydrocarbon being at least 98.5 wt % paraffins, less than 1 wt % bicyclic compounds, and less than 0.5 wt % total aromatics as measured by ASTM D2425; and   c) 5 to 40 weight percent, based on the Jet Fuel composition, of pinane.   
     
     
         9 . The jet fuel composition of  claim 8  wherein pinane is present in an amount of 5 to 35 weight percent, based on the blend. 
     
     
         10 . The jet fuel composition of  claim 8  wherein greater than 55 weight percent, based on combined components a) and b), of the synthetic paraffinic kerosene fuel component is present. 
     
     
         11 . The jet fuel composition of  claim 10  wherein pinane is present in an amount of 5 to 35 weight percent, based on the blend. 
     
     
         12 . The jet fuel composition of  claim 11  wherein greater than 60 weight percent, based on combined components a) and b), of the synthetic paraffinic kerosene fuel component is present. 
     
     
         13 . The jet fuel composition of  claim 8  wherein pinane is present in an amount of 10 to 35 weight percent, based on the blend. 
     
     
         14 . The jet fuel composition of  claim 13  wherein pinane is present in an amount of 10 to 25 weight percent, based on the blend. 
     
     
         15 . The jet fuel composition of  claim 8  wherein greater than 70 weight percent, based on combined components a) and b), of the synthetic paraffinic kerosene fuel component is present.
