Adsorption of Thiophene Out of Model Gasoline Using Metal Ion-Exchanged Zeolite

Article Preview

Abstract:

Adsorptions of organic sulfur compounds thiophene was carried out using metal ion-exchanged Y-zeolites. Na-Yzeolites exchanged with Ag+, La3+, Cu2+, Ni2+, Bi3+ ions were prepared by liquid ion exchange method. Ag+ and La3+ ions modified Yzeolites showed markedly high adsorptive capacities for Thiophene. The sulfur uptake increased in the order of Bi-Yzeolite < Ni-Yzeolite < CuY-zeolite < AgY-zeolite < LaY-zeolite for thiophene. The mole ratios of TP/Ag and TP/La were 0.098 and 0.071, respectively.
