Title: Fuel and base oil blendstocks from a single feedstock

Abstract: A method comprising providing a fatty acyl mixture comprising: (i) a C.sub.10-C.sub.16 acyl carbon atom chain content of at least 30 wt. % wherein at least 80% of the C.sub.10-C.sub.16 acyl carbon atom chains are saturated; and (ii) a C.sub.18-C.sub.22 acyl carbon atom chain content of at least 20 wt. % wherein at least 50% of the acyl C.sub.18-C.sub.22 carbon atom chains contain at least one double bond; hydrolyzing the mixture to yield a quantity of C.sub.10-C.sub.16 saturated fatty acids and C.sub.18-C.sub.22 unsaturated fatty acids; oligomerizing at least some of the C.sub.18-C.sub.22 unsaturated fatty acids to yield a quantity of C.sub.36+ fatty acid oligomers; hydrotreating at least some of the C.sub.10-C.sub.16 saturated fatty acids and at least some of the C.sub.36+ fatty acid oligomers to yield a quantity of diesel fuel blendstock and C.sub.36+ alkanes; and separating at least some of the diesel fuel blendstock from the C.sub.36+ alkanes.
