Abstract
Description
Technical Field
[0001] This invention relates to the field of catalyst technology, and specifically to the preparation and application of a supported nickel-based catalyst. Background Technology
[0002] Sugar alcohols, as an important class of starch-processed products, are widely used in food, pharmaceuticals, cosmetics, and other fields, and are key chemicals for achieving green and sustainable production in the chemical industry. Sorbitol is a highly representative sugar alcohol compound, with its market share and annual production far exceeding other sugar alcohol products. Furthermore, sorbitol's multifunctionality, renewability, and health benefits make it an indispensable part of modern chemical industry.
[0003] Sorbitol is a product of glucose hydrogenation via catalytic hydrogenation. Currently, Raney nickel is the most widely used hydrogenation catalyst in industry; however, due to its flammability and the tendency for active metal Ni to leach, the development of glucose hydrogenation catalysts remains a significant concern. Noble metal catalysts such as Ru exhibit excellent activity and sorbitol selectivity, but their large-scale industrial application is limited by cost. Chinese patent CN1214333A discloses a nickel-based alloy catalyst with a high specific surface area, achieving complete glucose conversion within 70 minutes, but requiring high reaction temperature and hydrogen pressure (140℃, 4.8MPa). Chinese invention patent CN111302893A discloses a supported copper-nickel alloy catalyst; at a reaction temperature of 100℃, the glucose conversion rate is only 85.2%, and the selectivity is 93.3%, indicating that its activity needs further improvement. Therefore, developing inexpensive, efficient, and stable novel nickel-based catalysts for glucose hydrogenation is of great significance. Summary of the Invention
[0004] The purpose of this invention is to propose a method for preparing a supported nickel-based catalyst. The preparation method is simple, and the high specific surface area can effectively enhance the dissociation of hydrogen and the adsorption and activation of substrate molecules such as glucose, thereby achieving efficient conversion of glucose and maleic anhydride.
[0005] This invention proposes a method for preparing a supported nickel-based catalyst, comprising: (1) Mix and stir nickel nitrate hexahydrate with lanthanide nitrate, add biomass template agent during stirring, and heat in a water bath to obtain wet gel. The molar ratio of C6 of biomass template agent to the total mass of nickel nitrate hexahydrate and nitrate hexahydrate is 1.5:1-5:1. (2) The wet gel is dried, pre-calcined, calcined, activated and passivated to obtain a supported nickel-based catalyst, wherein the pre-calcination temperature is 300-500℃.
[0006] Preferably, the biomass template agent is glucose (Glu), maltose (Mal), lactose (Lac), or soluble starch (SS).
[0007] More preferably, the biomass template agent is maltose, lactose, or soluble starch. The biomass template agent provided by the present invention has a high molecular weight, enabling it to form a larger specific surface area, thereby achieving a higher glucose conversion rate and sorbitol selectivity.
[0008] More preferably, the supported nickel-based catalyst has a specific surface area of 39.5-70.2 m². 2 g -1 The pore volume is 9.3-13.2 cm³. 3 g -1 The pore size is 8.6-13.2 nm.
[0009] Preferably, the pre-calcination temperature is 300-350℃, and the biomass template agent is soluble starch. Under these preferred conditions, the soluble starch can be stably decomposed, which can not only fully remove the template agent to avoid residual carbonization clogging the pores, but also prevent the precursor from prematurely sintering and causing pore collapse, thereby forming a connected and ordered mesoporous framework and promoting the high dispersion of Ni active sites, thus achieving optimal specific surface area and glucose hydrogenation performance.
[0010] More preferably, the supported nickel-based catalyst has a specific surface area of 69-70.2 m². 2 g -1 The pore volume is 12.1-13.2 cm³. 3 g -1 The pore size is 12.8-13.2 nm.
[0011] Preferably, the pre-calcination time is 5-6 hours.
[0012] Preferably, the lanthanide nitrate is cerium nitrate hexahydrate, lanthanum nitrate hexahydrate, strontium nitrate hexahydrate, or neodymium nitrate hexahydrate.
[0013] Preferably, the temperature of the water bath is 70-90℃.
[0014] Preferably, in step (2), the drying temperature is 110-130℃ and the time is 10-12h.
[0015] Preferably, the calcination temperature is 700-900℃ and the time is 5-6 hours.
[0016] Preferably, after calcination, the mixture is activated for 2-4 hours in an H2 atmosphere at 300-600℃.
[0017] Preferably, the passivation process is as follows: after the temperature drops to room temperature, passivation is carried out in an atmosphere of oxygen and nitrogen for 1-2 hours, wherein the oxygen content is 5-10%.
[0018] The present invention also provides the application of the supported nickel-based catalyst prepared by the method of preparing the supported nickel-based catalyst in the hydrogenation of glucose and maleic anhydride.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The biomass template agent provided by this invention has a high molecular weight and can construct a well-developed, interconnected hierarchical porous system during the sol-gel process. This promotes the diffusion and mass transfer of reactant molecules, reduces internal diffusion limitations, and thus improves glucose conversion and sorbitol selectivity.
[0020] This invention directly regulates the integrity of pore development and the size of specific surface area by adjusting the amount of biotemplating agent. If the amount of biotemplating agent is insufficient, the spatial confinement effect in the sol-gel process is weak, which cannot effectively guide the orderly assembly and lattice growth of the precursor. This makes it difficult to form a regular perovskite structure after calcination, and at the same time causes the collapse of the carrier pores and a significant decrease in specific surface area, which seriously affects the dispersibility of Ni species. When the amount of biotemplating agent is too large, the excessive pyrolysis of organic matter produces a large amount of carbon paper residue. These residues will block the pores and cover oxygen vacancies and active sites of metallic Ni, thereby affecting glucose conversion rate and sorbitol selectivity.
[0021] This invention, by controlling the pre-calcination temperature, can gently decompose the biological template agent and minimize the residual organic template during the calcination process. This prevents the residual organic template from undergoing severe carbonization at high temperatures, which would obstruct the pores and encapsulate the active species. At the same time, it avoids premature sintering and pre-grain coarsening of the precursor due to excessively high pre-calcination temperatures, which would lead to pore collapse, a sharp reduction in specific surface area, and damage to the uniform distribution and close contact interface of metal ions necessary for the perovskite structure.
[0022] The synergistic effect of the above three factors ultimately determines the catalyst's pore structure, active site density, surface oxygen vacancy concentration, and acid-base properties, thereby significantly improving its catalytic activity and product selectivity in reactions such as aqueous hydrogenation of glucose and selective hydrogenation of maleic anhydride.

[0024] The present invention will be further illustrated by specific examples below. All raw materials involved in the implementation examples are commercially available or obtained through simple laboratory processing.
[0025] Example 1 Weigh out 5 mmol of cerium nitrate hexahydrate and 5 mmol of nickel nitrate hexahydrate, dissolve them in 20 mL of water, and stir at room temperature for 1 h to form a uniform green transparent solution. Then, slowly add 50 mmol of glucose while stirring.
[0026] The solution was then heated in a water bath at 80°C and stirred continuously for 2 hours until it became viscous, forming a green wet gel.
[0027] The wet gel was placed in a forced-air drying oven and dried at 110°C for 24 hours to obtain a brown solid foam.

[0036] Example 3 Weigh out 5 mmol of cerium nitrate hexahydrate and 5 mmol of nickel nitrate hexahydrate, dissolve them in 20 mL of water, and stir at room temperature for 3 h to form a uniform green transparent solution. Then, slowly add 15 mmol of lactose while stirring.
[0037] The solution was then heated in a water bath at 70°C and stirred continuously for 3 hours until it became viscous, forming a green wet gel.
[0038] The wet gel was placed in a forced-air drying oven and dried at 120°C for 24 hours to obtain a brown solid foam.

[0041] Example 4 Weigh out 5 mmol of cerium nitrate hexahydrate and 5 mmol of nickel nitrate hexahydrate, dissolve them in 20 mL of water, and stir at room temperature for 2 h to form a uniform green transparent solution. Then, slowly add 0.05 mmol of soluble starch while stirring.
[0042] The solution was then heated in a water bath at 90°C and stirred continuously for 1.5 hours until it became viscous, forming a green wet gel.
[0043] The wet gel was placed in a forced-air drying oven and dried at 130°C for 24 hours to obtain a brown solid foam.

[0045] The method for evaluating the hydrogenation performance of the catalyst is the same as in Example 1. The evaluation results are shown in Table 1, and the specific surface area and pore volume results are shown in Table 2.
[0046] Comparative Example 1 The difference from Example 1 is that the biomass template agent selected is arabinose.
[0047] Comparative Example 2 The difference from Example 2 is that citric acid was selected as the biomass template agent.
[0048] Table 1. Evaluation results of glucose hydrogenation activity of different catalysts Table 2. Specific surface area and pore size results for different catalysts This invention plays a crucial role in optimizing the catalyst structure by introducing template agents such as glucose, maltose, lactose, and soluble starch. The molecular weight of the template agent is positively correlated with its structure-directing ability. From monosaccharides (arabinose, glucose) to disaccharides (maltose, lactose), and then to polysaccharides (soluble starch), the molecular size and degree of polymerization of the template agent increase significantly. The larger the molecular weight of the template agent, the more developed and interconnected the hierarchical porous system can be constructed in the sol-gel process. This greatly promotes the diffusion and mass transfer of reactant molecules and reduces internal diffusion limitations.
[0049] In contrast, metal ions form overly stable metal complexes under the strong carboxyl coordination of the conventional chelating agent citric acid. This strong coordination restricts the migration of metal species during subsequent heat treatment, leading to the aggregation of active components. Overly stable precursors require more intense reduction conditions, which is not conducive to the formation of perovskite-derived structures with good crystallinity and controllable defects.
[0050] Comparative Example 3 Compared to Example 2, the difference is that the molar ratio of template agent C6 to total metal nitrates is 8:1.
[0051] Comparative Example 4 Compared to Example 4, the difference is that the molar ratio of template agent C6 to total metal nitrates is 0.5:1.
[0052] Table 3 Catalytic performance of Ni / CeO2-Mal under different template agent dosages Table 4 Catalytic performance of Ni / CeO2-SS with different template agent dosages Table 5. Specific surface area and pore size of Ni / CeO2-SS under different template agent dosages This invention optimizes the structure and surface properties of perovskite-derived catalysts by controlling the amount of biomass template agent. Insufficient template agent results in weak spatial confinement during the sol-gel process, failing to effectively guide the ordered assembly and lattice growth of the precursor. This leads to difficulty in forming a regular perovskite structure after calcination, causing pore collapse of the support and a significant decrease in specific surface area, severely affecting the dispersibility of Ni species. Excessive template agent leads to excessive organic matter pyrolysis, generating a large amount of carbonaceous residue. These residues clog pores and cover oxygen vacancies and active Ni sites on the CeO2 surface. Therefore, precise control of the template agent amount is beneficial for constructing porous structures and maximizing active sites, thereby promoting catalyst activity.

Before use, the catalyst was placed in a tube furnace and activated at 500°C in an H2 atmosphere for 4 hours. After the temperature dropped to room temperature, it was passivated in a 10% O2 / N2 atmosphere for 2 hours to obtain Ni / CeO2-SS catalysts at different pre-calcination temperatures.
[0055] The method for evaluating the hydrogenation performance of the catalyst is the same as in Example 1. The evaluation results are shown in Table 5, and the specific surface area and pore volume results are shown in Table 6.
[0056] Example 6 5 mmol of cerium nitrate hexahydrate and 5 mmol of nickel nitrate hexahydrate were dissolved in 20 mL of water and stirred at room temperature for 2 h to form a homogeneous, transparent green solution.

The foam was ground into powder and pre-calcined in a muffle furnace at 400 °C for 2 h to remove excess template agent, followed by calcination at 800 °C for 5 h. Before use, the catalyst was placed in a tube furnace and activated at 500 °C in an H2 atmosphere for 4 h. After cooling to room temperature, it was passivated in a 10% O2 / N2 atmosphere for 2 h to obtain Ni / CeO2-SS catalysts at different pre-calcination temperatures.

The solution was then heated in a water bath at 90 °C and stirred continuously for 1.5 h until the solution became viscous, forming a green wet gel. The wet gel was placed in a forced-air drying oven and dried at 130 °C for 24 h to obtain a brown solid foam. The foam was ground into powder and pre-calcined in a muffle furnace at 500 °C for 1 h to remove excess template agent, followed by calcination at 800 °C for 5 h. Before use, the catalyst was placed in a tube furnace and activated at 500 °C in an H2 atmosphere for 4 h. After cooling to room temperature, it was passivated in a 10% O2 / N2 atmosphere for 2 h to obtain Ni / CeO2-SS catalysts at different pre-calcination temperatures.
[0059] The method for evaluating the hydrogenation performance of the catalyst is the same as in Example 1. The evaluation results are shown in Table 6, and the specific surface area and pore volume results are shown in Table 7.
[0060] Comparative Example 5 The difference compared to Example 4 is that the pre-calcination temperature is 100°C.
[0061] Comparative Example 6 The difference compared to Example 7 is that the pre-calcination temperature is 700°C.
[0062] Table 6. Effects of different pre-calcination conditions on catalyst performance Table 7. Specific surface area and pore size of Ni / CeO2-SS under different pre-calcination conditions The pre-calcination step introduced in this invention not only gently removes the organic template agent, but also pre-constructs a stable porous precursor framework, laying a crucial structural foundation for the subsequent formation of highly ordered perovskite-type composite oxides. When the pre-calcination temperature is too low, the template agent decomposes incompletely, and the residual organic matter undergoes severe carbonization in the subsequent high-temperature stage, severely clogging the pores and encapsulating active species, hindering the uniform crystallization and interface formation of the perovskite precursor. When the pre-calcination temperature is too high, although the template agent can be completely removed, it will cause premature sintering and grain coarsening of the precursor, leading to pore collapse, a sharp reduction in specific surface area, and destruction of the uniform distribution and close contact interfaces of metal ions necessary for the perovskite structure. Only at a moderate pre-calcination temperature (300-500℃) can the template agent decompose stably, forming a continuous and ordered mesoporous framework to optimize mass transfer, and stabilizing the distribution of metal ions and inhibiting premature grain growth. This leads to the formation of a perovskite-derived structure with suitable crystallinity, abundant defects (such as oxygen vacancies), and strong metal-support synergy during subsequent high-temperature calcination, ultimately resulting in a high-performance catalyst.
[0063] Example 8 40 mg of Ni / CeO2-Mal catalyst and 3 mL of 10 wt% maleic anhydride γ-butyrolactone solution were added to an 8 mL stainless steel high-pressure reactor. The reaction temperature was 70 °C, the hydrogen pressure was 3 MPa, and the reaction time was 4 h. The conversion rate of maleic anhydride and the selectivity of succinic anhydride were determined by gas chromatography. The catalyst activity evaluation results are shown in Table 8.
[0064] Example 9 40 mg of Ni / CeO2-SS catalyst and 3 mL of 20 wt% maleic anhydride γ-butyrolactone solution were added to an 8 mL stainless steel high-pressure reactor. The reaction temperature was 80 °C, the hydrogen pressure was 4 MPa, and the reaction time was 3 h. The conversion rate of maleic anhydride and the selectivity of succinic anhydride were determined by gas chromatography. The catalyst activity evaluation results are shown in Table 8. Table 8. Evaluation results of maleic anhydride hydrogenation activity of different catalysts Figure 1 The image shows the electron microscopy morphology of the Ni / CeO2-SS catalyst prepared in Example 4. As can be seen from the image, Ni nanoparticles are uniformly dispersed on the CeO2 support surface without significant agglomeration, exhibiting good dispersion. This indicates that at a suitable pre-calcination temperature, the soluble starch template agent decomposes smoothly, effectively inhibiting premature migration and sintering of metal ions, thereby stabilizing the highly dispersed state of the Ni species.
[0065] The catalyst involved in this invention is adaptable to a variety of reaction systems. Its multi-level porous structure, highly dispersed Ni active centers, and oxygen-vacancy-rich CeO2 support, obtained through precise control of the pre-calcination step, not only provide an ideal reaction environment for the hydrogenation of biomass sugar molecules (such as glucose), but also meet the stringent requirements of selective hydrogenation of maleic anhydride. Its structural advantages are universally applicable to a variety of catalytic systems involving the selective hydrogenation of multifunctional molecules, demonstrating broad application potential.
