Sakuneka, Auteur ; Reinier J. J. Nel, Auteur ; Arno de Klerk, Auteur Année de publication : 2008 Article en page(s) : p. 7178–7183 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Solid phosphoric acid Benzene Olefin oligomerization Résumé : A refinery with a solid phosphoric acid olefin oligomerization unit can reduce the benzene content of its motor-gasoline by co-feeding the benzene-containing material to that unit. It has been shown that benzene co-feeding has little disruptive impact on olefin oligomerization, and >80% benzene conversion to alkylated benzenes has been demonstrated during a commercial test run on an industrial unit. Benzene conversion is insensitive to reactor inlet temperature in the range of 160−180 °C and remains better than 80% at liquid hourly space velocities of up to 1.5 h−1. A high propene content in the olefinic feed promotes benzene alkylation, and although butene-rich feeds can be employed, benzene conversion is lower.
