Abstract

The invention discloses a preparation method and application of a non-sulphurized hydrodeoxygenation catalyst, and belongs to the technical field of catalyst synthesis. In order to solve the problems of the conventional hydrodeoxygenation catalyst, the invention provides the preparation method of the non-sulphurized hydrodeoxygenation catalyst with a unique porous structure. The preparation method comprises the following steps: firstly preparing an MIL-77 precursor solution, then adding heteropoly acid to obtain a mixed solution, then performing a hydrothermal reaction, and finally centrifuging, washing and drying to obtain an HPA@MIL-77 non-sulphurized hydrodeoxygenation catalyst which can be applied to a hydrodeoxygenation reaction of a model compound with phenol as bio-oil. The non-sulphurized hydrodeoxygenation catalyst prepared by the preparation method provided by the invention can be synthesized into the HPA@MIL-77 catalyst by a one-step method, and MIL-77 with high specific surface area can effectively control the HPA loading amount and regulate the acidity of the catalyst, so that improvement on the selectivity of a hydrodeoxygenation product is facilitated.

Description

technical field [0001] The invention relates to a preparation method and application of a non-sulfurized hydrogenation deoxygenation catalyst, belonging to the technical field of catalyst synthesis. Background technique [0002] Biomass-derived oil obtained by pyrolysis of biomass has become one of the main research directions of biomass energy. Liquid bio-oil is a black acidic liquid, including acids, phenols, ketones, aldehydes, alcohols, esters and furans. It is a complex mixture with a very high oxygen content (40-50%). Although bio-oil has the advantages of easy storage and transportation, a large number of oxygenated compounds cause problems such as high viscosity, strong acidity, low calorific value and poor stability of bio-oil, which seriously limits the substitution of bio-oil for fuel oil, such as gasoline, diesel and Application of high quality oil such as aviation kerosene. Therefore, the amount of effective hydrogen in the bio-oil can be increased and the oxy...
