Comparison of synthesized H-Al-MCM-41 with different Si/Al ratios for benzene reduction in gasoline with propylene

Benzene reduction in gasoline was investigated with propylene over synthesized mesoporous H-Al-MCM-41 with Si/Al=15, 29 and 42 as catalysts in order to produce more environmental friendly gasoline. The resulting catalysts were characterized by XRF, XRD, FTIR, TGA, BET and TPD-NH3 techniques. The results of alkylation of C6-cut obtained from gasoline indicated that the synthesized mesoporous H-AL-MCM-41 with Si/Al=15 is the most active catalyst among the synthesized catalysts due to high crystallinity, favorable textural properties and large bronsted acidity. The higher conversion of benzene (47.88%) was observed over H-Al-MCM-41 with Si/Al=15 at B/P=1 and T=200°C.
