The production of a more environmentally suitable gasoline by removing substantial portions of benzene by alkylation with propylene was studied on three real feedstocks with different chemical composition. Nine consecutive tests of 1 h were carried out for each feedstock, in a batch system with a 2/1 benzene:propylene mole ratio at 220 °C using the same Beta catalyst. The results obtained were compared with pure benzene alkylation reactions. With the increase of benzene concentration in the feedstock, benzene conversions improved. Presence of olefin compounds even in traces caused oligomers formation and finally catalyst deactivation.
Graphical abstractThe production of a more environmentally suitable gasoline by removing substantial portions of benzene by alkylation with propylene using zeolite Beta as catalyst was studied on four feedstocks with different chemical composition. With the increase of benzene concentration in the feedstock, benzene conversions improved. Presence of olefin compounds even in traces caused oligomers formation and finally catalyst deactivation.Figure optionsDownload full-size imageDownload as PowerPoint slide
