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.
