Patent number: 9856189Abstract: Methods and compositions are provided for refining natural oils and for producing high-weight esters, high-weight acids, and/or high-weight derivatives thereof, wherein the compositions are made by cross-metathesizing low-weight unsaturated esters or low-weight unsaturated acids having hydrocarbon chain lengths less than or equal to C24 with an olefin feedstock, thereby forming a metathesized product composition including high-weight esters or high-weight acids having hydrocarbon chain lengths greater than C18, wherein at least a portion of the hydrocarbon chain lengths in the metathesized product are larger than the hydrocarbon chain lengths in the starting feedstock.Type: GrantFiled: June 20, 2016Date of Patent: January 2, 2018Assignee: Elevance Renewable Sciences, Inc.Inventors: Bruce Firth, Brian M. Pease, Alexander D. Ilseman, Garrett Zopp, Timothy A. Murphy, Robin Weitkamp, Michelle Morie-Bebel
