Comparison of performance of Ni–Mo/γ-alumina catalyst in HDS and HDN reactions of main distillate fractions
Abstract A bimetallic nickel–molybdenum catalyst supported on γ-alumina was synthesized by the two-step incipient wetness impregnation technique. The activity of the prepared Ni–Mo/γ-alumina catalyst was evaluated in a down flow fixed-bed micro-reactor. In this way, hydrodesulfurization (HDS) and hy...
