Abstract
Jet boiling range compositions are provided that include at least a portion of an isoparaffinic blend component, along with a method for making such a blend component. The highly isoparaffinic nature of the blend component can allow the isoparaffinic blend component to be used in combination with both conventional/mineral jet fuel boiling range fractions as well as non-traditional feeds (such as Fischer-Tropsch fractions) to form jet fuel fractions and/or jet fuel blending component fractions.
Claims28
A blended jet boiling range composition comprising:
- 30 vol % to 99 vol % of an isoparaffinic blend component containing 80 wt % or more of isoparaffins, 5.0 wt % or less of olefins, and 5.0 wt % or less of C19+ hydrocarbons;
- and 1.0 vol % to 70 vol % of a mineral jet boiling range fraction, the composition comprising a T10 distillation point of 205° C. or less, a final boiling point of 300° C. or less, a freeze point of −40° C. or lower, and 2.0 wt % or more of C17-C18 hydrocarbons.
A blended jet boiling range composition comprising:
- 1.0 vol % to 20 vol % of an isoparaffinic blend component, and 80 vol % to 99 vol % of a mineral jet boiling range fraction, the isoparaffinic blend component comprising 80 wt % or more of isoparaffins, 5.0 wt % or less of olefins, and 5.0 wt % or less of C19+ hydrocarbons, the composition comprising a T10 distillation point of 205° C. or less, a final boiling point of 300° C. or less, and a freeze point of −40° C. or lower.
A blended jet boiling range composition comprising:
- 1.0 vol % to 99 vol % of an isoparaffinic blend component containing 80 wt % or more of isoparaffins, 5.0 wt % or less of olefins, and 5.0 wt % or less of C19+ hydrocarbons;
- and 1.0 vol % to 99 vol % of a mineral jet boiling range fraction, the composition comprising a T10 distillation point of 205° C. or less, a final boiling point of 300° C. or less, a freeze point of −40° C. or lower, and i) 10 wt % or more of C9 hydrocarbons, ii) a flash point of 50° C. or higher, or iii) a combination of i) and ii).
