Preparation, characterization and application of alumina nanoparticles with multiple active component for oxidation desulfurization

Abstract

This study investigated the oxidation desulfurization; by new metal salts used in the preparation of Nano catalyst. Alumina nanoparticles were successfully treated by multiple active components of zinc oxide and magnesium oxide to improve its surface properties for oxidative desulfurization of feedstock (kerosene). The alumina Nanoparticles with 12.5%ZnO and 12.5%MgO metal oxides loading showed significant oxidation desulfurization efficiency. The alumina Nano particles with multiple oxides containing 25% optimum metals loading showed higher desulfurization efficiency. Characterization of the home-prepared Nano catalyst was made by precipitation on surface area of Nano alumina analyzer using N2 adsorption. The Nano catalyst properties (surface area = 107.4292 m2 g−1, total pore volume = 0.633291 cm3g−1, Langmuir surface area = 154.6115 m2g−1) and surface chemistry of the as-synthesized alumina with zinc and magnesium oxides, oxidation sulfur content with higher removal desulfurization. Three principal operating parameters have been considered which are reaction temperature, reaction time, and weight of Nano catalyst. The experimental results showed that the chemical nature of multiple oxides showed higher conversion (84.6%) at 190 °C, 45 min and 1gm used in batch reactor.
