Abstract
Several new homemade nano-catalysts are prepared here to reduce sulfur compound found in light gas
oil (LGO) utilizing the adsorption desulfurization technique. The effect of different support materials
(Fe2O3, Cr2O3 and CdO) having the same particle size (20 nm) on the adsorptive desulfurization performance for loading 5% nickel sulfate (5 wt%NiO) as an active component for each catalyst, is studied.
Oxidative desulfurization process (ODS) in a novel digital baffle batch reactor (DBBR) is used to evaluate
the performance of the catalysts prepared. Moderate operating conditions are employed for the ODS process. The efficient new nano-catalysts with for the removal of sulfur are found to be 93.4%, 85.6% and
62.1% for NiO/Fe2O3, NiO/Cr2O3 and NiO/CdO, respectively at 175 deg C, 75 min and 2 ml of H2O2. The best
kinetic model and the half-live period for the nano-catalysts related to the relevant reactions have also
been investigated here.
