Effect of graphene functionalizing on the performance of NiMo/graphene in HDS and HDN reactions
Abstract In this research, to remove sulfur and nitrogen compounds from heavy naphtha, various nanocatalysts were prepared through supporting NiMo over nanoporous graphene and evaluated in hydrodesulfurization and hydrodenitrogenation reactions. The nanoporous graphene was initially functionalized i...
