AI Technical Summary

Technical Problem

Existing catalysts suffer from poor hydrophilicity and poor contact between active components and reactants in catalytic hydrodeoxygenation reactions, which limits their catalytic performance. In addition, the preparation process is complex and not environmentally friendly.

Method used

The catalyst was prepared by hydrothermal crystallization. By mixing and calcining an alkaline source, a silicon source and a noble metal precursor, a catalyst with catalytic hydrogenation and deoxygenation function was formed. The catalyst has good hydrophilicity and a large specific surface area, and the active components are in good contact with the reactants.

Benefits of technology

It improves the catalytic effect of the catalyst, simplifies the preparation process, and the composition of the catalyst is easy to control, making it suitable for large-scale production.

Abstract

This invention relates to the field of catalysts, and discloses a catalyst with catalytic hydrogenation and deoxygenation function, its preparation method, and its application. The preparation method of the catalyst includes: hydrothermal crystallization of an alkali source, a silicon source, and optional additives; mixing the resulting hydrothermal crystallization product with a noble metal precursor and then calcining it; wherein OH... ‑ The weight ratio of the alkali source to the silicon source (calculated as SiO2) is 0.01-290. The catalyst described in this invention exhibits good hydrophilicity, a large specific surface area, and good contact between the supported active component and the reactants, resulting in better catalytic performance. Furthermore, the preparation process of this invention is simple, the composition is easily controlled, and it is easy to scale up.
