Bottom oil derived from ethylene crackers contains a high concentration of polycyclic aromatic hydrocarbons (PAHs). Selective conversion of these compounds into BTX (benzene, toluene, and xylenes) offers a promising route for improving resource utilization efficiency and reducing environmental impact. In particular, utilizing PAHs as chemical feedstocks enables the effective use of underutilized carbon resources and contributes to the reduction of CO2 emissions. In this study, a series of multifunctional hydrotreating catalysts were developed for BTX production using model compounds such as 1-methylnaphthalene and dibenzothiophene. The effects of metal species and loading amount on catalytic performance were systematically investigated.
