    Abstract: The present disclosure provides a process for producing hydrocarbons from a feedstock containing organic material of biological origin. The process includes: providing a feedstock containing organic material of biological origin; pre-treating the feedstock in one or more pre-treatment stages to obtain a purified feedstock; subjecting the purified feedstock to pre-hydrotreatment to obtain a stream of partly hydrotreated feed; subjecting the stream of partly hydrotreated feed to hydrotreatment to obtain a stream of hydrocarbons; distilling the stream of hydrocarbons to obtain at least two fractions, a first heavy bottom fraction which is removed from the process, and a second middle fraction, which is collected for further processing; and subjecting the collected middle fraction to isomerisation to obtain an isomerised stream of hydrocarbons.

    Abstract: The present disclosure relates to a base oil hydrocarbon composition containing a total paraffin content of from 50 wt. % to 65 wt. %, of which at least 90% are isomerised paraffins, a naphthenes content of from 25 wt. % to 35 wt. %, aromatics in an amount of 4 wt. % to 16 wt. % based on a total weight of the composition, and wherein the composition has a pour point of −26° C. to −32° C. and a kinematic viscosity 100° C. of 7 to 17 cSt. The base oil hydrocarbon composition is obtained from a feedstock containing organic material of biological origin, such as crude tall oil. A process produces a base oil hydrocarbon product from a feedstock including organic material of biological origin.

    Abstract: 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.
