چکیده

In this research, Ni(8%)/TiO2/Zeolite NaX nanophotocatalyst was synthesized and
evaluated as a desulfurizer catalyst from hydrophane 10 base oil. Various tests,
including X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy-
Dispersive X-ray Analysis (EDXA), Transmission Electron Microscopy (TEM), Atomic
Force Microscopy (AFM), and BET/BJH were used to evaluate the photocatalyst
synthesis process. Initially, using Design of Experiment (DOE) technique, optimum
influential parameters were predicted, and 2D plus 3D diagrams were plotted.
Then, 50 ml of oil containing 3782 ppm total sulfur, 0.6 g catalyst, 0.8 g adsorbent,
and 3 h contact time were able to remove 20% of sulfur when exposed to the
visible light. Sulfur was measured at all steps using inductively coupled plasma
(ICP) technique. The final results suggested that the nanophotocatalytic process
is a feasible way when compared to difficult and complicated steps with harder
conditions.
