PURPOSE: A producing method of an aromatic product using a transition metal phosphide catalyst is provided to enable use the catalyst capable of using for a long time compare to a conventional catalyst for the hydro-desulfurization/denitrification. CONSTITUTION: A producing method of an aromatic product using a transition metal phosphide catalyst comprises the following steps: distill-separating coal tar to obtain bottom oil and distilled oil(U1); and performing the hydro-desulfurization/denitrification with the distilled oil under the presence of the transition metal phosphide catalyst for removing sulfur, nitrogen, sulfur compounds, or nitrogen compounds from the distilled oil(U2). The transition metal phosphide catalyst contains more than one compound selected from the group consisting of Ni2P, Co2P, Fe2P, MoP, and WP, and is deposited in more than one carrier selected from silica alumina, alumina, zinc oxide, zirconia, ceria, silica, zeolite, mesoporous silica, clay, USY zeolite, saponite, or titania. |
