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.

Abstract: A method for producing a blended jet boiling range composition stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce an isoolefinic stream; subjecting at least a portion of the isoolefinic stream to a hydroprocessing process with hydrogen as treat gas to produce an isoparaffinic stream having no greater than 10 wt % olefin content; and using least a portion of the isoparaffinic stream to create the blended jet boiling range.

Abstract: Compositions are provided that include at least a portion of an isoparaffinic blend component, an iso-olefinic blend component, or a combination thereof, along with a method for making such a blend component. The highly isoparaffinic and/or iso-olefinic nature of the blend component can allow a blend component to be used in combination with both conventional/mineral fractions as well as non-traditional feeds to form fuel fractions and/or fuel blending component fractions. Examples of fuels that can be formed by making a blend that includes an isoparaffinic and/or iso-olefinic blend component include diesel fuels, marine gas oils, and various types of marine fuel oils, such as very low sulfur fuel oils.

Abstract: A method for producing an isoolefinic stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit comprising a serial reactor and a lights removal column, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; and wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; and oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce the isoolefinic stream.
