Synthesis, characterization, and catalytic performance of NiMo catalysts supported on different crystal alumina materials in the hydrodesulfurization of diesel
Different crystal alumina were synthesized from two sources of AlCl3 and Al(NO3)3. The correlation between different crystal forms with HDS efficiency was discussed. The NiMo/δ2-Al2O3 catalyst showed the best hydrotreating performance. The synergy of texture property and MSI attributed to high activity of catalysts. HDS and HDN efficiencies followed: NiMo/δ-Al2O3 > NiMo/γ-Al2O3 > NiMo/θ-Al2O3.
