Synthesize of Zirconia-Promoted NiMo Nanocatalyst supported on red mudvia impregnation method used in Hydrodesulfurization of oil cuts

In recent years, many studies have been done on reusing waste materials like red mud, because it consists of various oxides like iron oxides, alumina and silica that can be used as support for hydrodesulfurization catalysts. The commonhydrodesulfurization catalysts are CoMo/Al2O3and NiMo/Al2O3. Addition of secondary promoter such as zirconia is proposed as a usefulsolution for increasing catalyst activity and production of standard fuels. In this paper, NiMo nanocatalyst supported on activated red mud was prepared by impregnation method containing various amounts of Zr promoter and its catalytic performance was evaluated for hydrodesulfurization (HDS) process of iso diesel and light diesel in the atmospheric pressure. The red mud support along with synthesized nanocatalysts werecharacterized with XRF, XRD, FESEM, BET and FTIR techniques. Analytical techniques related to NiMo/ZrO2-ARM nanocatalysts characterizationrevealed that zirconia addition resulted in uniform dispersion of particles on the support surface and destroying of agglomerate, an increase in the activephase and a decreasein the formation of Ni spineless. The catalyticactivity of nanocatalysts in the hydrodesulfurizationprocess showed that NiMo/ZrO2-ARMwith10wt.%zirconiahadthebestcatalyticactivityforisodieseland15wt.%zirconiaforlightdiesel
