1. A hydrodesulfurization catalyst consisting of:
(a) a first metal oxide having a weight percentage in a range of 4-9% with respect to a total weight of the hydrodesulfurization catalyst;
(b) a second metal oxide having a weight percentage in a range of 15-26% with respect to the total weight of the hydrodesulfurization catalyst;
(c) a third metal oxide having a weight percentage in a range of 4-7% with respect to the total weight of the hydrodesulfurization catalyst;
(d) γ-alumina in a weight percentage in a range of 40-65% with respect to the total weight of the hydrodesulfurization catalyst; and
(e) at least one chelating agent having a weight percentage in a range of 1-7% with respect to the total weight of the hydrodesulfurization catalyst, wherein the at least one chelating agent is a combination of citric acid and glutamic acid, and
wherein the hydrodesulfurization catalyst has a BET surface area in a range of 155 to 210 m2/g.
