A process for controlled manufacturing of olefin trimers and olefin tetramers is disclosed, wherein the olefin monomers are processed into olefin trimers and olefin tetramers by a two-step catalytic process involving separation and recycling of reaction products.

Process for manufacturing olefin trimers and tetramers

The present disclosure relates to methods for producing renewable base oil and other valuable renewable fuel components from a feedstock of biological origin comprising free fatty acids and glycerides. The feedstock is first separated to two or more effluent streams containing a fatty acid fraction and glyceride fraction. The glycerides are hydrolyzed to free fatty acids and glycerol, and the fatty acids thus obtained are recycled to the separating. The fatty acids are then converted to the base oil by ketonisation, hydrodeoxygenation and hydroisomerisation. The glycerol is converted to propanols by selective hydrogenolysis.

Method for producing renewable base oil and renewable fuel components

The present disclosure relates to a process and a production unit that are used to catalytically manufacture olefin trimers from olefin monomers, and wherein olefin dimers are recycled after dimerization reaction, and reacted with olefin monomers in an addition reaction.

Olefin trimerization

Hydrotreatment of biological oil is disclosed for producing renewable base oil and a diesel oil from low value biological oils. Low value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil in an efficient manner by first separating at least part of the free fatty acids from the feedstock and then processing separately this free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed is processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream.

Process for the production of renewable base oil, diesel and naphtha

A method and system for producing ketones, suitable for manufacture of base oil or diesel fuel components, from a feedstock of biological origin containing fatty acids and/or fatty acid derivatives, and being at least partly in liquid form, by subjecting the feedstock to a catalytic ketonisation reaction, wherein the ketonisation reaction is carried out in a system having one or more ketonisation reactor(s) (A', B&#x2032;) each with at least one ketonisation catalyst bed (G&#x2032;). The method and system for producing ketones use a gas containing COproduced in the ketonisation reactors as a carrier gas.
