Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. Hydrotreatment of the oxygenated feedstock occurs in a first hydrotreating bed arranged downstream of a polishing bed. A gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed arranged upstream of the first hydrotreating bed together with fresh hydrogen. The process effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation, and the arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen. Part of the product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor.

Abstract: The present disclosure describes a process for producing poly-?-olefins. The process includes providing at least one ?-olefin monomer and a catalyst, and letting the at least one ?-olefin monomer react in the presence of the catalyst to form a mixture of poly-?-olefins (PAO). The obtained mixture of poly-?-olefins is fractionated to two PAO fractions wherein the two PAO fractions are a first fraction of PAO having a kinematic viscosity of 5 cSt or lower and a second fraction of PAO having a kinematic viscosity of more than 5 cSt. Optionally a recycle fraction is also obtained in the fractionation and at least a part of the recycle fraction including dimers of the ?-olefins can be recycled back to the reaction step.

Abstract: 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.

Abstract: The present invention relates to a method for producing renewable hydrocarbons from an oxygen containing renewable feedstock, the feedstock comprising dissolved impurities selected from impurities comprising phosphorus and impurities comprising at least one metal, the feedstock further comprising at least one of triglycerides and free fatty acids. The method comprises obtaining a net elementary charge based on phosphorus and the at least one metal of a first feedstock; mixing the first feedstock with an elementary charge balancing component to obtain the feedstock to be purified, which feedstock to be purified has a net elementary charge within a range of from ?5 to 15 mmol elementary charge/kg of the feedstock to be purified; subjecting the feedstock to be purified to heat treatment at a temperature of 180-400° C.
Abstract: The present invention relates to a method for reducing an amount of dissolved impurities in an oxygen containing renewable feedstock, the dissolved impurities being selected from impurities comprising phosphorus and impurities comprising at least one metal. The method comprises obtaining a net elementary charge of a first feedstock; mixing the first feedstock with an elementary charge balancing component to obtain the feedstock to be treated, whereby the feedstock to be treated has a net elementary charge which is closer to zero net elementary charge than the net elementary charge of the first feedstock; and subjecting the feedstock to be treated to a heat treatment at a temperature of 180-400° C. in order to precipitate compounds containing said phosphorus and said at least one metal.
Abstract: A process for selection of a pretreatment for a renewable feedstock comprising organic nitrogen impurities prior to feeding said feedstock into catalytic hydrotreating and isomerization can include removal of nitrogen impurities to protect the catalysts of the following process steps from deactivation and prolongs the catalyst life. Some of the nitrogen impurities disclosed herein have not been found or reported previously in renewable feedstocks.
