Experimental Study on Unsupported Nano-MoS2 Catalyst

Abstract

Six kinds of unsupported MoS₂ hydrodesulfurization catalysts for ultra low-sulfur diesel oil and the precursor of MoS₂ catalyst, nano-sized MoO₃, were synthesized with a novel hydrothermal reduction method. The influence of the synthetic methods, the precursor (MoO₃) of MoS₂ catalyst, the concentration of reactants and the pH values on the growth morphology of MoS₂ were systematically investigated and thoroughly analyzed. The MoS₂ fibers showed lots of defects and they were easily bended, which increased the number of active sites on the catalyst and easily met the requirements for the deep hydrotreating desulfurization of diesel oil.
