Abstract

Abstract:

The NiMoP/γ-Al2O3 catalysts with different metal loadings were prepared by vacuum incipient wetness impregnation method. The catalysts were characterized by BET, XRD, H2-TPR, TPS, and HRTEM, and evaluated in terms of their performance in hydrotreating of gas oil. The results show that the catalyst with metal loading of 30% has the maximum number of active sites, the best active phase structure, and pore structure, leading to the most outstanding gas oil hydrotreating performance.

Key words: catalyst, active mental loading, gas oil, hydrotreating
