The invention relates to a process for the manufacture of diesel range hydrocarbons wherein a feed is hydrotreated in a hydrotreating step and isomerised in an isomerisation step, and a feed comprising fresh feed containing more than 5 wt % of free fatty acids and at least one diluting agent is hydrotreated at a reaction temperature of 200-400° C., in a hydrotreating reactor in the presence of catalyst, and the ratio of the diluting agent/fresh feed is 5-30:1.

Process for the manufacture of diesel range hydrocarbons

The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. The triglyceride containing feedstock is first split to provide a mixture containing fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. The oily phase containing fatty acids is subjected to fractionation, whereby specific fractions may be refined to products with controlled hydroprocessing. Products may contain paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.

Process for integrated production of renewable fuels and chemicals

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

A process is disclosed for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process includes subjecting a feedstock containing free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. An ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of the metathesis product includes recovery of a fraction containing or consisting essentially of C16 fatty acid esters, which is subjected to ketonisation reaction conditions to produce long chain ketones, which after hydrotreatment meet requirements for a renewable base oil. Ketonisation reaction produces renewable alkene usable in metathesis reaction.

Renewable base oil production engaging metathesis

The invention relates to a process for the manufacture of diesel range hydrocarbons wherein a feed is hydrotreated in a hydrotreating step and isomerised in an isomerisation step, and a feed comprising fresh feed containing more than 5 wt % of free fatty acids and at least one diluting agent is hydrotreated at a reaction temperature of 200-400&#xb0; C., in a hydrotreating reactor in the presence of catalyst, and the ratio of the diluting agent/fresh feed is 5-30:1.

A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.

TiOcatalyst in ketonisation reactions to produce RBO

The present disclosure relates to a method for producing renewable ketones, paraffin waxes, base oil components and alkenes from a feedstock of biological origin, wherein the method includes ketonisation of esters of fatty acids and monohydric alcohols wherein the alcohols have carbon chain length of two or more.

A number of different branched hydrocarbon compounds (formula I) having a star-like configuration (S) are prepared from renewable oils containing fatty acids or derivatives containing fatty acids. The branched hydrocarbon compounds may be isolated individually or in mixtures, and may be used as part of base oils, such as renewable base oils (RBOs). A process for preparing the branched hydrocarbon compounds of formula I involve conditions that favour a trimerisation reaction followed by hydrotreating conditions. The compounds of formula I may be made by catalytically treating renewable material in a process, and the compounds have desirable qualities relating to lubrication, cold flow as well as having a low Noack volatility.

Method for converting carboxylic acids and esters into base oil hydrocarbons

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.

A method for conversion of levulinic acid and to a hydrocarbon composition obtainable by the method. The method includes a step of providing a feedstock, a conversion step of subjecting the feedstock to a C&#x2014;C coupling reaction and a hydrotreatment, and a hydrodeoxygenation step. The content of levulinic acid dimer derivatives having 4 oxygen atoms subjected to the hydrodeoxygenation step is 20 wt.-% or more.
