Based on the carbon number distribution and sulfide distribution of hydrocarbon compositions in pyrolysis diesel, the effects of Salt A on the morphology, distribution and other properties of MoS2 loaded on γ-Al2O3 supports were investigated. Furthermore, the impacts of A-Z modification on the pore properties, acidic properties, active phase morphology and other characteristics of the catalysts were studied, leading to the preparation of a pyrolysis diesel hydrodesulfurization catalyst with high desulfurization activity and selectivity. Finally, the optimal process operating conditions were determined and pilot-scale evaluation was completed.
