Abstract: 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.
Abstract: A method comprising the steps of 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 olefin; oligomerizing at least some of the mixture to yield a second mixture comprising C36+ oligomers; hydrotreating the second mixture 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.
Abstract: Motor fuel compositions contain alkoxylation products of oxo oils or their fractions or esters thereof, which are alkoxylated with propene oxide and/or butene oxides and/or not more than minor aomunts of ethene oxide.
