Desulfurization of Gasoline over Nanoporous Nickel-Loaded Y-Type Zeolite at Ambient Conditions

Abstract

Desulfurization of heavy straight-run gasoline (HSRG) was accomplished over Ni (II) -Y zeolite. Na-Y zeolite, a nanoporous adsorbent, was synthesized and ion-exchanged with NH 4 NO 3 to obtain NH 4 -Y zeolite. The obtained material was then converted to H-Y zeolite by calcination. Ni-Y zeolite was prepared by solidstate ion exchange (SSIE) of H-Y zeolite using Ni(NO 3 ) 2 • 6H 2 O. The breakthrough curve for desulfurization of HSRG containing about 140 ppmw of sulfur compounds was obtained in a batch reactor at ambient conditions. The effects of temperature, Ni content in the zeolite framework, and aging of the zeolite on the desulfurization process were investigated. Ni-Y zeolite exhibited a high capability for the desulfurization of gasoline at ambient conditions.

“…Many studies have been conducted to develop adsorbents for the desulfurisation of transportation fuels using zeolites, 123,137,138 mesoporous materials 139 and activated carbons. [140][141][142][143] Salem and Hamid 144 studied the removal of sulfur from naphtha with a 550 ppm initial S-content in a batch reactor using activated carbon, zeolite 5A, and zeolite 13X as sorbents.…”

Metal supported on natural zeolite as catalysts for conversion of ethanol to gasoline

“…The metal sites ussually come from a supported transition metal, such as Ni, Mo, W, Co, or their combinations, oxide, or sulfide of group VIII and/or group VI B [3]. While, the acid sites come from alumina-silica [4][5][6], various zeolites such as ZSM-5 [7], Y [8,9] and beta [10], MCM-41, and amorphous silica-alumina.…”

Antibacterial and Regenerated Characteristics of Ag-zeolite for Removing Bioaerosols in Indoor Environment

“…There is lack of information about investigating air phase bioaerosol removal systems in a continuous-flow environment. In this study, a better reservoir of Y-type zeolite was used because of its relatively high ion exchange capacity and lattice stability (Inoue et al, 2008;Zhang et al, 2008;Dastanian and Seyedeyn-Azad, 2010;Talebi et al, 2010). Ag-zeolite (AgZ) composites were prepared and applied in an antibacterial system to reduce indoor bacterial and fungus counts.…”
