Abstract

A specific type of mesopore extrudates gamma alumina was prepared; which is applied as the catalyst in the heavy oil hydrodesulfurization unit. Extrudates gamma alumina has been devised the boehmite powder; several samples have been utilized to investigate the concentration and the number of acetic acid treatment effects on the textural properties. Textural properties of catalyst support have been characterized by X-Ray Diffraction, N2-adsorption/desorption techniques, the best results were observed at 25% acetic acid after three times treatments. The active metals (3.71%Molybdenium &1.43%Nickle) have been impregnated on the catalyst support. The prepared catalyst determined by X-Ray Fluorescence, N2- adsorption/desorption, bench scale reactor test, NH3-Temperature Programmed Desorption and Radial Strength techniques.
