QUANTITATIVE RELATIONSHIP BETWEEN CATALYST PROPERTIES AND HYDRODESULFURIZATION CONVERSION OVER NiMo/Al2O3

Abstract

Abstract: A series of NiMo/Al2O3 catalysts with different properties was obtained by controlling the metal loading. NiO loading, MoO3 loading and the MoS2 dispersion of the catalysts were considered and a “changing super geometric average” was applied to revise the existing model to establish a quantitative relationship between the catalyst properties and the HDS conversion. The results indicated that the average relative deviation for the modified model is only 1.13%. The optimum MoO3 and NiO loadings are 12%-14% and 3%-4%, respectively, as analyzed by the established model. The results also showed that hydrodesulfurization activity is more sensitive to the content of NiO loading.

Key words: NiMo/Al2O3 catalyst, mathematic model, metal loading, dispersion, hydrodesulfurization activity
