Preparation of Titanium Oxide-Fibrous Zeolite Y Catalyst for Desulfurization of Fuel

Abstract

In this study, TiO₂ supported on fibrous Zeolite Y (FY) was synthesized via ultrasonic co-impregnation for desulfurization of dibenzothiophene (DBT). The physicochemical properties of the prepared TiO₂/FY were characerized by XRD and TEM. Next, to determine the efficiency capacity of TiO₂/FY in the fuel desulfurization process, several photocatalytic tests with different parameters including time (0 – 180 min), TiO₂/FY dosage (0.1 - 5 g/L), initial pH (2 - 8), and initial concentration (50 – 400 mg/L) were conducted accordingly. A high DBT removal (87%) was successfully accomplished at the optimum conditions of 5 g/L TiO₂/FY, pH 8, and 300 mg/L, which may be contributed from the fibrous structure as recorded by TEM and high crystallinity from the XRD analysis. It can be concluded that the TiO₂/FY own great potential to be applied as an efficient material for the fuel desulphurization.
