Abstract

A method for preparing fuel components from crude tall oil. Feedstock containing tall oil including unsaturated fatty acids is introduced to a catalytic hydrodeoxygenation to convert unsaturated fatty acids, rosin acids and sterols to fuel components. Crude tall oil is purified in a purification by washing the crude tall oil with washing liquid and separating the purified crude tall oil from the washing liquid. The purified crude tall oil is introduced directly to the catalytic hydrodeoxygenation as a purified crude tall oil feedstock. An additional feedstock may be supplied to the catalytic hydrodeoxygenation.
