Abstract
Desulfurization of thiophene from model gasoline was carried out by using large charge number metal (Bi, Sb, Zr and Ru) ion modified NH4Y-zeolite by batch method. The sulfur uptake increased in the order of HY (0.85 mg/g) < BiY-1 (1.06 mg/g) < SbY-1(1.24 mg/g) < ZrY-1 (1.25 mg/g) < RuY-1 (1.35 mg/g). Sulfur uptake was influenced by Ru contentof RuY, which increased in the order of RuY-0.25 (1.11mg/g) < RuY-1 (1.41mg/g) < RuY-0.5 (1.68 mg/g). Sulfur removal was influenced by aromatics of model gasoline, i.e., sulfur removal of RuY-0.5 (42%) showed higher selectivity for thiophene than CeY-1 (24%) ones when model gasoline with toluene.
