Abstract
The new catalyst hydroisomerizes C18 paraffins from fatty acids to a high degree to produce a composition with an acceptable freezing point that retains 18 carbon atoms in the hydrocarbon molecules for jet fuel. The inventors have discovered a fuel composition that includes at least 14 wt.% of the hydrocarbon molecules with at least 18 carbon atoms and a freezing point of -40°C or less. The composition may also exhibit a final boiling point of 300°C or less. The hydroisomerization process may be once-through, or a portion of the product diesel stream may be selectively hydrocracked or recycled to hydroisomerization to obtain a fuel composition that meets jet fuel specifications.
