Heavy distillate composition

Abstract

A distillate boiling range composition is provided with an unexpected distribution of carbon chain lengths for the hydrocarbons in the composition. The composition corresponds to a distillate boiling range composition with a relatively narrow boiling range. Additionally, the narrow boiling range composition can have unexpectedly beneficial cold flow properties.

What is claimed is: 
     
         1 . A distillate boiling range composition, comprising 80 wt % or more of isoparaffins, 15 wt % or less of n-paraffins, a T10 distillation point of 290° C. or more, a T90 distillation point of 325° C. or less, and i) 0.1 wt % or more of total aromatics, ii) 0.07 wt % or more of one-ring aromatics, or iii) a combination of i) and ii). 
     
     
         2 . The composition of  claim 1 , wherein a difference between the T90 distillation point and the T10 distillation point is 20° C. or less. 
     
     
         3 . The composition of  claim 1 , wherein the composition has a cloud point of −20° C. or less. 
     
     
         4 . The composition of  claim 1 , wherein the composition comprises 85 wt % or more of isoparaffins. 
     
     
         5 . The composition of  claim 1 , wherein the composition comprises 0.5 wt % or more of naphthenes. 
     
     
         6 . The composition of  claim 1 , wherein the composition comprises 1.0 wt % or more of naphthenes, aromatics, or a combination thereof. 
     
     
         7 . The composition of  claim 1 , wherein the composition has a density of 800 kg/m 3  or less, or wherein the composition has a kinematic viscosity at 40° C. of 4.5 cSt or less, or a combination thereof. 
     
     
         8 . The composition of  claim 1 , wherein the composition comprises 1.0 wppm or less of oxygen, or wherein the composition comprises 10 wppm or less of sulfur, or a combination thereof. 
     
     
         9 . The composition of  claim 1 , wherein the composition comprises a final boiling point of 340° C. or less. 
     
     
         10 . The composition of  claim 1 , wherein the composition comprises 90 wt % or more of compounds having C 17 -C 20  carbon chains. 
     
     
         11 . The composition of  claim 1 , wherein the composition comprises a T 90  distillation point of 310° C. or less. 
     
     
         12 . The composition of  claim 1 , wherein the composition comprises 10 wt % or less of n-paraffins. 
     
     
         13 . A blended composition, comprising:
 1.0 wt % to 99 wt % of a distillate boiling range composition comprising 80 wt % or more of isoparaffins, 15 wt % or less of n-paraffins, a T10 distillation point of 290° C. or more, and a T90 distillation point of 325° C. or less; and   1.0 wt % to 99 wt % of one or more distillate fractions, one or more resid fractions, or a combination thereof.   
     
     
         14 . The blended composition of  claim 13 , wherein the blended composition comprises a T10 distillation point of 170° C. or more and a T90 distillation point of 370° C. or less. 
     
     
         15 . The blended composition of  claim 13 , wherein the blended composition comprises a T 90  distillation point of 500° C. or more. 
     
     
         16 . The blended composition of  claim 13 , wherein the distillate boiling range composition has a cloud point of −20° C. or less. 
     
     
         17 . The blended composition of  claim 13 , wherein the blended composition comprises one or more distillate fractions, the blended composition comprising 25 wt % or more of the distillate boiling range composition, a cloud point of the blended composition being lower than a cloud point of the one or more distillate fractions. 
     
     
         18 . The blended composition of  claim 13 , wherein the one or more distillate fractions, one or more resid fractions, or a combination thereof comprise at least one of a bio-derived fraction and a Fischer-Tropsch fraction. 
     
     
         19 . The blended composition of  claim 13 , wherein the blended composition comprises 10 wt % to 90 wt % of the distillate boiling range composition. 
     
     
         20 . The blended composition of  claim 13 , wherein the distillate boiling range composition has a T90 distillation point of 310° C. or less, a final boiling point of 340° C. or less, or a combination thereof.
