Problems solved by technology

Due to the difficulty of catalyst recovery, the low concentration of reaction substrates, and the high price of alkynes as raw materials, its wide-scale application in industry is limited.
In addition, literature has shown that the use of ordered mesoporous carbon materials to support Ru catalysts in CO 2 / H 2 Furfural can be converted to 3-acetylpropanol under the O system (GreenChem., 2018, 20, 1770), but the catalyst is extremely unstable in an acidic environment and cannot be recycled

Embodiment 1-3

[0028] Add 0.1g furfural and 5g water into a 50ml autoclave. At the same time, add 50mg ammonium molecular sieve supported ruthenium bifunctional catalyst (2wt% of Ru mass loading) into the reactor, pass 1.0MPa hydrogen into it, and seal the Parr kettle. The autoclave was heated to 80°C for 25 minutes to react. After 10 hours of reaction, the reaction was stopped and cooled to room temperature. The liquid product and the catalyst were separated by centrifugation. The liquid product was analyzed by gas chromatography. The product yield is (number of moles of carbon in 3-acetylpropanol) / (total number of moles of carbon in the raw materials)×100%, and other products include furfuryl alcohol, cyclopentanone, cyclopentanol, 1,4-pentanediol, The yield was not calculated. The results of the reaction are shown in Table 2.

[0030]

[0031] It can be concluded from Table 2 that in the reaction of furfural to prepare 3-levulinol, the catalytic activity and selectivity of ammonium...

Embodiment 4-7

[0033] 0.1g furfural and 5g water are added to a 50ml autoclave. At the same time, 50mg Ru / H-Beta-N catalyst (Ru mass loading is 2%) is added to the reactor, 0.5MPa hydrogen is introduced, and the Parr kettle is closed. The autoclave was heated to a certain temperature within minutes to react. After 10 hours of reaction, the reaction was stopped and cooled to room temperature. The liquid product and the catalyst were separated by centrifugation, and the liquid product was analyzed by gas chromatography. The reaction results are shown in Table 3 below.

[0034]

[0035] It can be concluded from Table 3 that with Ru / H-Beta-N as the catalyst, the reaction temperature is between 60-120°C, which is beneficial to the selective preparation of 3-acetylpropanol from furfural.

Embodiment 8-9

[0037] Add 0.1g furfural and 5g water into a 50ml autoclave. At the same time, add 50mg Ru / H-Beta-N catalyst (2% Ru mass loading) into the reactor, pass 0.5-3MPa hydrogen, and seal the Parr kettle. The autoclave was heated to 80°C for 25 minutes to react. After 10 hours of reaction, the reaction was stopped and cooled to room temperature. The liquid product and the catalyst were separated by centrifugation. The liquid product was analyzed by gas chromatography. The reaction results are shown in Table 4 below.

[0038]

[0039] It can be concluded from Table 4 that with Ru / H-Beta-N as the catalyst, furfural can obtain 3-acetylpropanol with high selectivity when the hydrogen pressure is 0.5-3.0MPa.

Description

Technical field [0001] The invention belongs to the field of medicine and chemical industry, and relates to a catalyst for preparing 3-acetylpropanol from furfural, specifically a supported ruthenium catalyst with an ammonium molecular sieve as a carrier. [0002] The invention relates to the preparation method and application of the above-mentioned catalyst. Specifically, the ammonium molecular sieve carrier is prepared by an ion exchange method, the active component Ru is supported by the impregnation method, and the catalyst is used to prepare furfural under different preparation and reaction conditions. The activity, selectivity and stability of levulinol. Background technique [0003] Furfural (furfuryl alcohol) is one of the important biomass-based platform compounds and the only important industrial raw material that can be completely extracted from agricultural and forestry wastes. Because furfural is very active in its own chemical properties, many high value-added chemic...
