1. Introduction
Lately, the method of the in situ hydrogenation has been proposed to upgrade the quality of bio-oil. In this method, liquid hydrogen donor solvents were used to generate hydrogen instead of external source of hydrogen. Ton and Fisk used acids as hydrogen donors to hydrogenate model compounds of bio-oil and raw bio-oil over Pd and Nickel based catalysts [1,2]. Xu investigated the methanol's aqueous phase reforming and the coupling on the in situ hydrogenation of bio oil model compounds phenol and acetone over Raney Ni catalyst [3]. Wang reported liquid phase in situ hydrodeoxygenation of bio-derived phenol to cyclohexene and cyclohexane over Raney Ni and Nafion/SiO2 with methanol as hydrogenation donor [4]. Zeolite solid acids, including Y-type zeolite, ZSM-5 and Beta-type zeolite, were regarded to be one of the most promising catalysts in the application of bio-oil upgrading and have been widely used in acid catalyzed reaction such as dehydration, isomerization, cracking, alkylation, as well as promoting esterification between alcohols and acids in raw bio-oil [5–7]. However, the effect of zeolite solid acids on the in situ hydrogenation of bio-oil has not been reported. In this paper, we firstly systematically investigated the effect of zeolite solid acids on the in situ hydrogenation of bio-oil. Phenol was chosen as a model compound of phenols in bio-oil and was upgraded using the in situ hydrogenation over Ni catalyst and zeolite solid acids including Hbeta and HZSM-5 with different Si/Al ratio. And the effect of the quantity of catalysts and the stability of the catalysts were also studied.
