  • Patent number: 11959034
    Abstract: An integrated production plant system includes, at one production site at least two plants of different kinds selected from a renewable paraffinic fuel plant to produce renewable paraffinic fuel in a renewable paraffinic fuel process, a renewable fatty acid alkyl ester (FAAE) fuel plant to produce renewable FAAE fuel in a renewable FAAE process, a renewable base oil plant to produce renewable base oil in a renewable base oil process, and a renewable chemical plant to produce renewable chemical in a renewable chemical process. Each of the processes is provided with a respective renewable feed, where the feed of each of the processes originates from a common renewable system feed, and the feed to at least one of the processes is altered for example by directing at least part of the feed of at least one of the processes to another of the processes.
    Type: Grant

  • Publication number: 20230339828
    Abstract: Herein is provided a process for combined renewable 1-decene and renewable carboxylic diacid production from a fatty acid ester containing feedstock, wherein the feedstock is first subjected to metathesis reaction conditions, recovery of 1-decene and then to microbial oxidation to yield diacids in a fermentation broth. Diacids of unusual carbon chains lengths are thereby obtainable.

  • Patent number: 11795124
    Abstract: 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.
