Abstract:
1. A method for preparing fuel components from crude tall oil, the method comprising: purifying crude tall oil by washing the crude tall oil with washing liquid, separating the purified crude tall oil from the washing liquid, introducing the purified crude tall oil as a purified crude tall oil feedstock directly to a catalytic hydrodeoxygenation comprising ring-opening of components of the purified tall oil feedstock, to convert unsaturated fatty acids, rosin acids and sterols to fuel components, supplying a product stream of the hydrodeoxygenation from the catalytic hydrodeoxygenation to a separation, where various usable fuel components are separated to various liquid hydrocarbon fractions issuing from the separation as various product streams separately from gases discharged from the separation, and leading only a product stream corresponding to a diesel fraction through an isomerizing for producing a hydrocarbon fraction usable as a diesel fuel or a diesel fuel component.
