The trimetallic NiWMo catalyst exhibits higher hydrodesulfurization activity compared with the bimetallic NiMo(W) catalyst. However, nonsynchronous sulfurization of Mo and W during leads to either an increase in slab size or incomplete sulfurization. This limitation hinders further improvement NiMoW catalyst's performance. Therefore, it is essential investigate factors influencing process catalyst, achieving synchronous W. Herein, NiWMo/Al2O3 prepared by impregnation method. During sulfurization, interaction between additive Ni main metals reduces temperature while increasing degree for metals. Additionally, difference. As a result, highest rates Ni, Mo, are observed within 290–375 °C, where close contact species inhibits unrestricted growth Mo(W)S2 length forms Ni–Mo–W–S active phase. Consequently, lamella stacking number reduced length, which results increased exposure edges present enhanced sites on enables 4,6-dimethyl-2-benzothiophene conversion reaches 100% at 320 °C.
