Hydrocarbon composition and method for producing a hydrocarbon composition

Abstract

A method comprises conducting hydrodeoxygenation and optionally isomerization of raw material, wherein the method further comprises one or more solvent extraction steps and optionally hydrogenation to remove aromatic and/or naphthenic hydrocarbons from the material. The original aromatic and/or naphthenic content of the raw material is less than 21 vol-%. In the method, the aromatic and/or naphthenic content is reduced by more than 45%, preferably by more than 60%. A composition contains hydrocarbons produced by said method, wherein the total aromatic and/or naphthenic hydrocarbon content of the composition is less than a predefined low value, and C15-C20 i-paraffins are the main fraction of the hydrocarbon content of the composition, weight basis.
