In recent years, polycyclic aromatic hydrocarbons (PAHs) have been generated as by-products in the petroleum refining process. Selectively converting these by-products into BTX (benzene, toluene, and xylene) can improve resource utilization efficiency and indirectly reduce CO₂ emissions. Therefore, this study investigates multifunctional catalysts capable of selectively hydrogenating PAHs into monocyclic aromatics and further converting them into BTX through desulfurization and alkyl ring-opening reactions. Various acidic support materials and active metals were used to prepare the multifunctional catalysts, and their performance was tested in the hydrotreating of 1-methylnaphthalene (1-MN) and phenanthrene. Additionally, the effects of reaction conditions, acidic support materials, and active metals were examined.
