Hydrodeoxygenation (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.

使用 HZSM-5 和 Ni2P/HZM-5 催化剂对模型生物油进行催化加氢脱氧:相互作用的理解

对作为模型生物油的混合物 1(乙酸和苯酚)和混合物 2(丙酮、乙酸、苯酚、4-乙基愈创木酚、糠醛和水)进行加氢脱氧 (HDO) 以研究相互作用。Ni 2 P/HZSM-5 催化剂表现出比空白 HZSM-5 更高的活性。由于对活性相的吸附能力不同,乙酸的转化率随着温度的升高而提高,这与苯酚的值相反。丙酮可通过乙酸自酮化形成。低温有利于酯化反应,而高温则主要通过苯酚和苯的烷基取代促进烷基取代酚和芳烃的合成。提出了具有主要反应的模型生物油HDO的两种反应网络。
