Abstract

See full text

Herein is provided a process for producing renewable products, such as alkenes, from a feedstock of biological origin. The process includes subjecting a feedstock including fatty acid glycerides and optionally free fatty acids, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. The ester stream thereby obtained is then fractionated and a fraction including esters of unsaturated C18 fatty acids is subjected to metathesis conditions in the presence of an alkene to obtain metathesis products. Fractionation of the metathesis products includes recovery of at least renewable 1-decene, and unsaturated C10-C15 fatty acid esters.
