Preparation method of composite metal material catalyst and its application in the preparation of 5-hmf

Abstract

The invention relates to a preparation method of a composite metal material catalyst and its application in the preparation of 5-HMF. The preparation method of the composite material is as follows: 1) preparing the reactant solution A for preparing the metal organic framework compound, immersing the pretreated metal foam substrate in the above solution, and preparing the composite material B with the metal foam as the substrate by a hydrothermal synthesis method; 2) Mix the material B synthesized in step 1) with the precursor solution containing Ni (Ru, Pt, Pd) ions, and use the impregnation method to obtain the precursor C; 3) Precursor C at 300‑1200 o C under the condition of oxygen barrier calcination, a composite metal material catalyst based on metal foam is prepared. The reaction of catalyzing cellulose to prepare 5-HMF is carried out in a magnetic induction heating reactor. The ferromagnetic base metal foam of the composite metal material is heated at a fixed point under the action of an alternating magnetic field, shortening the reaction time, reducing energy consumption, and reducing coking of the catalyst. , so that the reaction can be carried out smoothly and efficiently, and 5-HMF with high added value can be obtained.

Description

technical field [0001] The invention relates to a preparation method of a composite metal material catalyst and its application in the preparation of 5-HMF, belonging to the field of biomass resource utilization. Background technique [0002] In the process of globalization, the sustainable development of energy and environment has become a common concern of the whole world and all mankind. However, the excessive development and use of traditional fossil fuels has led to a sharp increase in greenhouse gas emissions, causing a series of environmental problems. Therefore, the energy work in the new era is on the development and utilization of renewable resources. Cellulose is the most abundant renewable resource in the world, which can be transformed into high value-added chemical 5-HMF through physical, chemical and biological methods. 5-HMF has active chemical properties and can be used as an intermediate in many reactions to generate various derivatives through oxidation,...
