Characterization of the prepared catalyst was achieved by using Energy Dispersive X-Ray Analysis&nbsp; (EDAX), scanning electron microscopy (SEM), BET surface area, pore volume , Bulk density, X-ray diffraction analysis (XRD) and Fourier-transform infrared spectroscopy (FTIR). AMK was modified as a bifunctional catalyst with active metal (Co and Mo). The hydrodesulfurization (HDS) efficiency was evaluated and compared with the traditional catalyst (CoMo-Al2O3) in a hydrotreating reaction carried out in one stage reactor at temperature 375 oC, pressure 40 bar, LHSV 1hr-1, and H2/HC ratio 200 vol. ratio.&nbsp; 62.2% and 90% of hydrodesulfurization efficiency were achieved for prepared catalyst (CoMo-AMK) and commercial CoMo-Al2O3 respectively at the same operating conditions.</p>}, number={2}, journal={Journal of Petroleum Research and Studies}, author={AlKhafaji, Khlood S. and Al-Zaidi, Bashir Y. and Shakor, Zaidoon M. and Hussein, Sattar J.}, year={2022}, month={Jun.}, pages={64-80} }
