Abstract
Molybdenum sulfides (MoS2)are efficient hydrodesulfurization (HDS) catalysts widely used in crude oil desulfurization. This paper described the synthesis of MoS2 and Co/MoS2nanomaterials by laser pyrolysis method. Here, we investigated two catalysts sample MoS2 and Co/MoS2, which were active for deep hydrodesulfurization reaction. Sulfide catalysts were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM), and tested in the dibenzothiophene (DBT) HDS reaction. It was found that pure MoS2 and Co/MoS2 nanomaterials was obtained with hollow spheres form. And Co/MoS2catalyst has much better initial activity compared to the reference commercial catalyst.
