Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

The preparation method of this catalyst is to utilize the unsaturated cubane-like structure, M cation with catalytic activity is introduced into the cluster core unit. By using the vertex vacancy as the capturing center, and adjusting the impregnation temperature to maximize the loading of the cluster precursor, as well as depending on the electrostatic adsorption of the support and the confinement of the cluster structural unit, the number of S vacancies and the distance between S vacancies and Miso sites are effectively controlled through liquid phase reduction and atmosphere treatment at room temperature to obtain supported X3MSx/Al2O3 catalyst with Miso-Vs synergistic sites. The method of the present invention achieves the joint enhancement of the activity, product selectivity, and stability of unsaturated carbon oxygen bond selective hydrogenation, carbon chlorine bond selective hydrogenation dechlorination, and carbon hydrogen bond dehydrogenation reactions. This catalyst is mainly used in various catalytic reaction processes in the fields of petrochemical, fine chemical, environmental chemical, and other fields. It has outstanding catalytic performance, excellent activity, selectivity, and good recyclability, and is easy to recover and reuse.
