Abstract:

Gallium atoms have been introduced into the framework of Y zeolite by treating the zeolite with an aqueous solution of ammonium hexafluoro gallate. The synthesized Y zeolite ([Ga]AlY) was characterized by means of X-Ray Diffraction (XRD), N₂ adsorption, Infrared spectrophotometer (IR) and Inductively Coupled Plasma (ICP). The results indicated that Ga has been substituted into the faujasitic framework. Hydrodesulfurization (HDS) of various model fuels containing about 500 μg/g sulfur has been studied over the [Ga]AlY. The activity of the [Ga]AlY catalysts on HDS reaction is highly affected by the temperature and kind of sulfide in model fuels. The conversion for thiophene, benzothiophene (BT) and dibenzothiophene (DBT) in model fuel 1, 2 or 3 was 81.2%, 60.7% and 37.2% respectively. Compared with the model fuel 1, 2 and 3, the conversion of every sulfide in model fuel 4 was much lower which can be due to the competitive adsorption between between the three of them.
