Publication number: 20220049172Abstract: The present disclosure is related to a multistep process for producing renewable gasoline components from a glyceride containing feedstock. The glycerides are split to provide a stream containing fatty acids, or esters of fatty acids, and another stream containing glycerol and water. Glycerol, preferably as crude glycerol recovered from splitting, is next converted to propanols at vapor phase, providing a renewable propanol gasoline component. Another renewable gasoline component is obtained from hydroprocessing of the fatty acids or esters thereof, as a renewable paraffinic naphtha component. Blending the renewable components can provide a novel 100% renewable gasoline.Type: ApplicationFiled: December 20, 2019Publication date: February 17, 2022Applicant: Neste OyjInventors: Marja TIITTA, Anna KARVO, Ulla KIISKI, Terhi KOLEHMAINEN, Jukka MYLLYOJA, Ville PAASIKALLIO
