  • Process for manufacture of liquid fuel components from renewable sources
    Patent number: 10501693
    Abstract: A method for producing liquid fuel components from renewable oil. A fresh feedstock including saturated fatty acids is subjected to dilution by an organic lipophilic solvent. The solvent has a low phosphorus and metal impurity content, less than 5 ppm and less than 10 ppm, respectively. Dilution is performed before and/or during purification by at least one pretreatment process for removal of phosphorus and metal impurities. Subsequently, the resulting purified feedstock is fed into at least one post-treatment process suitable for producing liquid fuel components.
