Abstract
ABSTRACT Reducing sulfur and nitrogen compounds is essential in producing clean fuels for providing a green environment. In this regard, a novel nanocatalyst has been proposed for Hydrodesulfurization (HDS) and Hydrodenitrogenation (HDN) of heavy naphtha. To this end, Ni-Mo was loaded on nanoporous graphene (Ni-Mo/NG) through the incipient wetness impregnation method. The synthesized nanocatalyst was characterized by FE-SEM, ICP, BET, FTIR, XRD and TPR methods. The catalytic activity of the Ni-Mo/NG catalyst was evaluated at 290oC and 30 bar. For the synthesized Ni-Mo/NG catalyst, conversions of total sulfur, total nitrogen and R-SH compounds (mercaptans) were obtained as 99.5, 99.4 and 99.3%, respectively, which shows considerable enhancement in comparison to the Ni-Mo/γ-Alumina industrial catalyst.
