摘要

This invention relates to the field of renewable oil compositions and especially to the use of renewable oil compositions for production of hydrocarbon compositions, which can be used for traffic fuels and other solutions. Especially, the current invention relates to a composition comprising free fatty acids and triglycerides, in a concentration of free fatty acids from 15 wt-% to 80 wt-% and the rest being predominantly triglycerides. The invention relates also to a method for producing hydrocarbons from a renewable oil feedstock, in which the feedstock comprising free fatty acids from 15 wt-% to 80 wt-%, and the rest being predominantly triglycerides is subjected to a pretreatment process followed by a hydrotreatment process for obtaining hydrocarbons.
