Embodiment 1

[0022] A kind of preparation method of nickel-aluminum spinel catalyst, carry out hydrothermal reaction after mixing organic matter, aluminum source and nickel source, then collect hydrothermal reaction product and roast to obtain required nickel-aluminum spinel catalyst; The organic matter is For terephthalic acid, trimesic acid or methyl trimesate, the calcination temperature is 400-600°C.

[0023] The preparation method of the nickel-aluminum spinel catalyst is synthesized by a one-step method, and the operation is simple and convenient; and the nickel-aluminum spinel catalyst can be formed by roasting at a low temperature without high temperature conditions. In addition, it should be emphasized that the preparation method of a highly dispersed and easily reducible supported nickel-aluminum catalyst provided in Chinese patent CN106582655A is an amorphous nickel-aluminum catalyst. And the present invention is by adding nickel source in situ, that is, adding organic matter, a...

Embodiment 2

[0027] A nickel-aluminum spinel catalyst, which is prepared by the preparation method of the nickel-aluminum spinel catalyst provided in Example 1, has a specific nickel-aluminum spinel structure.

Abstract

The invention relates to the technical field of chemical materials, and provides a nickel aluminum spinel catalyst and a preparation method thereof. The preparation method is as follows: mixing an organic substance, an aluminum source and a nickel source for hydrothermal reaction, and collecting a hydrothermal reaction product for calcining to obtain the desired nickel aluminum spinel catalyst; the organic substance is terephthalic acid, trimesic acid or trimethyl 1,3,5-benzenetricarboxylate, the calcination temperature is 400 to 600 DEG C. The preparation method of the nickel aluminum spinelcatalyst can obtain a specific nickel aluminum spinel structure, and has the advantages of simple preparation process and low reduction temperature. The invention also provides the nickel aluminum spinel catalyst prepared by the preparation method of the nickel aluminum spinel catalyst.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a nickel-aluminum spinel catalyst and a preparation method thereof. Background technique [0002] Catalysts are widely used in all walks of life, whether in the traditional chemical, pharmaceutical, biological fields, or in the improvement of economic benefits, the development and utilization of clean energy, and environmental protection and governance, catalysts play a very important role. In short, the preparation and application of catalysts are related to the survival and development of human beings. [0003] Supported catalysts play a pivotal role in the field of catalysis due to their high activity and selectivity, easy recovery and reuse, and good stability. Nickel metal has been widely concerned due to its high activity and low cost in reactions such as biomass catalytic gasification, ethanol steam reforming, methane carbon dioxide reforming, bio-oil hydrogena...
