Abstract

Hydrodeoxygenation (HDO) is one of the effective methods to upgrade biomass pyrolysis oil, but the development of a low-cost, high-performance HDO catalyst still faces enormous challenges. In this work, a facile and eco-friendly approach is developed to synthesize the Ni₂P@hierarchical HZSM-5 catalyst. Structure and acidity of the catalyst can be controlled by simply adjusting the proportions of ammonia solution and the silicon to aluminum ratio, which are closely related to the performance of the catalyst. Experimental results reveal that the Ni₂P@hierarchical HZSM-5 catalyst with Si/Al = 85 under NH₃·H₂O/Ni = 14 exhibits the highest activity of 98% guaiacol conversion, along with a 78.8% yield of cyclohexane (reaction conditions: 300 °C, 3 MPa H₂). In addition, the guaiacol reaction network is provided.
