Fuel and base oil blendstocks from a single feedstock

摘要

A method comprising providing a fatty acyl mixture comprising: (i) a C10-C16 acyl carbon atom chain content of at least 30 wt. % wherein at least 80% of the C10-C16 acyl carbon atom chains are saturated; and (ii) a C18-C22 acyl carbon atom chain content of at least 20 wt. % wherein at least 50% of the acyl C18-C22 carbon atom chains contain at least one double bond; hydrolyzing the mixture to yield a quantity of C10-C16 saturated fatty acids and C18-C22 unsaturated fatty acids; oligomerizing at least some of the C18-C22 unsaturated fatty acids to yield a quantity of C36+ fatty acid oligomers; hydrotreating at least some of the C10-C16 saturated fatty acids and at least some of the C36+fatty acid oligomers to yield a quantity of diesel fuel blendstock and C36+ alkanes; and separating at least some of the diesel fuel blendstock from the C36+ alkanes.
