Abstract
AbstractHydrodeoxygenation (HDO) of Mixture 1 (acetic acid and phenol) and Mixture 2 (acetone, acetic acid, phenol, 4‐ethylguaiacolis, furfural, and water) as model bio‐oils was performed to investigate the interactions. Ni2P/HZSM‐5 catalysts exhibited higher activity than blank HZSM‐5. The conversion rate of acetic acid enhanced with the increase of temperature, contrary to the value of phenol due to the differential adsorption capacity on active phases. Acetone can be formed by self‐ketonization of acetic acid. Low temperatures favored esterification, while high temperatures promoted the synthesis of alkyl‐substituted phenols and aromatic hydrocarbons via mainly alkyl substitution of phenol and benzene, respectively. Two reaction networks of model bio‐oil HDO with the main reactions were proposed.
