High-Temperature Hydrogenation of the Phenolic Fraction of Coal Tar from the AO Shubarkol Komir with Free and Bound Hydrogen in the Presence of MoO₃

Abstract—The results of the high-temperature hydrogenation of phenol and the phenolic fraction of coal tar from the AO Shubarkol Komir by-product coke plant in the presence of MoO₃ with the use of coke oven gas components as hydrogenating and alkylating agents are reported. When the fraction was hydrogenated in the СО–Н₂О system, phenol was alkylated with methanol formed as a result of water gas reaction along with the reduction of phenols to aromatic hydrocarbons. The interaction of phenol with the СО–Н₂О and СО–Н₂ systems under similar conditions led to the formation of phenol reduction (benzene, toluene, and xylenes) and alkylation (cresols and xylenols) products.
