AI Technical Summary
Traditional bio-oil catalysts are difficult to effectively contact the reactant hydrogen in the water-oil two-phase system, resulting in low catalytic efficiency. Existing support such as alumina and titanium dioxide are highly hydrophilic and preferentially dissolved in the aqueous phase, which is unable to effectively participate in the hydrodeoxygenation and deoxygenation process of organic matter in the oil phase.
Using amphiphilic oxides as support, the transition metal catalyst precursor and the hydrophilic oxide support are mixed and calcined, and then reduced, treated in a hydrophobic modifier to form an amphiphilic oxide support, ensuring that the catalyst is evenly distributed in the water and oil phases and increasing the contact area.
The contact area between the catalyst and the reactants is increased, the efficiency of hydrodeoxygenation of bio-oil is improved, and the water and oil two-phase emulsion is stabilized. It is suitable for the hydrodeoxygenation process under different requirements.

Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of catalyst preparation, and more specifically, relates to a catalyst supported on an amphiphilic oxide, a preparation method thereof, and an application thereof. Background Art
[0002] Bio-oil is a renewable liquid fuel produced by pyrolysis of biomass, which is expected to slow down the consumption of fossil energy and reduce carbon emissions. However, due to its disadvantages such as high oxygen content, high water content, low calorific value, and high acidity, it must be hydrodeoxygenated and upgraded before use. Bio-oil consists of a water-oil two-phase system. The aqueous phase contains small molecule organic oxygen-containing compounds, and the oil phase mainly contains macromolecular aromatic compounds. The reactant hydrogen is easily soluble in the organic phase, while in the traditional catalytic upgrading process of bio-oil, the catalyst is easily deposited in the aqueous phase, which results in the difficulty for the catalyst to effectively contact the reactant hydrogen, thereby reducing the catalytic efficiency. To address the above problems, there is an urgent need to develop a catalyst that can efficiently catalyze in a water-oil two-phase system.
[0003] Pickering emulsion is an emulsion that uses "amphiphilic" solid particles - containing both hydrophilic groups and hydrophobic groups - to replace liquid emulsifiers to stabilize the water-oil two-phase system. Loading a catalyst on the surface of the "amphiphilic" solid particles can significantly increase the contact area between the reactants and the catalyst and improve the catalytic efficiency of the water-oil two-phase system. Common supports for bio-oil hydrodeoxygenation, such as alumina, titanium dioxide, and silica, etc., can often provide good stability, and some can also provide acidic sites and oxygen storage capacity, etc. However, since most of them are highly hydrophilic supports, they are preferentially dissolved in the aqueous phase during water-oil two-phase catalysis, while most of the reactants are dissolved in the oil phase, resulting in their inability to participate well in the hydrodeoxygenation process of the organic matter in the oil phase, and the catalytic efficiency is relatively low. Therefore, there is an urgent need to develop a preparation method of a catalyst supported on an amphiphilic oxide to increase the contact area between the catalyst and the reactants and improve the hydrodeoxygenation efficiency of bio-oil. Summary of the Invention
[0004] In view of the above-mentioned defects or improvement requirements of the prior art, the present invention provides a catalyst supported on an amphiphilic oxide, a preparation method thereof, and an application thereof. The purpose is to prepare an amphiphilic oxide as the support of the catalyst, thereby solving the technical problem of low hydrodeoxygenation efficiency caused by the non-uniformity of the water-oil two-phase of bio-oil.
[0005] To achieve the above object, according to one aspect of the present invention, a preparation method of a catalyst supported on an amphiphilic oxide is provided, including the following steps:
[0006] (1) Mix the transition metal catalyst precursor particles with the hydrophilic oxide support particles and then calcine them, and then introduce a reducing gas into the calcined product;
[0007] (2) Place the product obtained in step (1) into the hydrophobic modifier solution, ultrasonicate and then let it stand still to modify the hydrophilic oxide to obtain an amphiphilic oxide;
[0008] (3) Add water to the solution in step (2), then heat to evaporate the organic solvent in the hydrophobic modifier solution, and finally freeze-dry to obtain the catalyst with the amphiphilic oxide as the carrier.
[0009] Preferably, the hydrophilic oxide in the hydrophilic oxide carrier particles is selected from one or more of alumina, titanium dioxide, and silica.
[0010] Preferably, the transition metal catalyst precursor in the transition metal catalyst precursor particles is selected from one or more of nickel acetylacetonate, ruthenium acetylacetonate, platinum acetylacetonate, iron acetylacetonate, nickel acetate, and ruthenium acetate.
[0011] Preferably, the hydrophobic modifier is selected from one or more of propyltrimethoxysilane, octyltrimethoxysilane, octadecyltrimethoxysilane, and cetyltrimethylammonium bromide;
[0012] Preferably, the organic solvent is selected from one or both of methanol and ethanol.
[0013] Preferably, the particle size of the hydrophilic oxide carrier particles is 10 - 1000 nm; the density of the hydrophilic oxide in the hydrophilic oxide carrier particles is 2 - 5 g / cm 3 .
[0014] Preferably, in step (1), the calcination is first carried out at 200 - 250 °C for 1 - 2 h, and then at 500 - 700 °C for 1 - 2 h.
[0015] Preferably, the mass of the transition metal catalyst precursor particles is 1% - 10% of the mass of the hydrophilic oxide carrier particles;
[0016] Preferably, the mass ratio of the hydrophobic modifier to the hydrophilic oxide carrier is 1:(1 - 30).
[0017] According to another aspect of the present invention, there is provided a catalyst with an amphiphilic oxide as the carrier prepared by the above-mentioned preparation method.
[0018] According to another aspect of the present invention, there is provided an application of the catalyst with an amphiphilic oxide as the carrier, which is used as a catalyst for hydrodeoxygenation of bio-oil.
[0019] Generally speaking, compared with the prior art by the above technical solutions conceived by the present invention, the following beneficial effects can be achieved:
[0020] 1. The present invention uses a hydrophilic oxide as a carrier. By mixing precursor particles of a transition metal catalyst with the hydrophilic oxide carrier particles and then calcining, the precursor particles of the transition metal catalyst are loaded into the pores of the hydrophilic oxide carrier particles, and the precursor of the transition metal catalyst is transformed into a transition metal oxide catalyst. Through reduction, the transition metal oxide catalyst is transformed into a transition metal element. Therefore, finally, a transition metal element is loaded on the hydrophilic oxide carrier particles through calcination. And a hydrophobic modifier is used to perform hydrophobic modification on the hydrophilic oxide carrier, so that the silicon-oxygen bond in the hydrophobic modifier is covalently bonded to the carrier (when the carrier is silica, the covalent bond formed is Si-O-Si; when the carrier is alumina, the covalent bond formed is Si-O-Al), thereby obtaining a catalyst with an amphiphilic oxide as the carrier. During the process of stabilizing the emulsion, the hydrophilic groups of the catalyst with an amphiphilic oxide as the carrier are adsorbed on the water side, and the lipophilic groups are adsorbed on the oil side, providing the ability to stabilize the emulsion.
[0021] 2. The present invention limits the particle size of the hydrophilic oxide carrier particles to be below 10 - 1000 nm. This is because the droplet size of the bio-oil emulsion after stirring and mixing is usually in the micron range, and the hydrophilic oxide carrier particles wrap around the surface of the emulsion droplets. Therefore, the particle size of the hydrophilic oxide carrier particles should be one order of magnitude smaller than the droplet size of the emulsion, so as to form stable emulsion droplets and improve the emulsification effect.
[0022] The density of the hydrophilic oxide is limited to 2 - 5 g / cm 3 , because only when the density of the hydrophilic oxide is small enough can it be ensured that the catalyst will not deposit to the bottom of the solution due to its own gravity after forming an emulsion with bio-oil, resulting in the destruction of the emulsion system.
[0023] 3. The present invention limits the mass of the precursor particles of the transition metal catalyst to be 1% - 10% of the mass of the hydrophilic oxide carrier particles. This is because the higher the catalyst loading, the higher the catalytic efficiency, but too high a catalyst loading is likely to cause pore blockage and reduce the catalyst activity.
[0024] 4. The catalyst prepared by the present invention can regulate its amphiphilicity by controlling the ratio between the hydrophobic modifier and the hydrophilic oxide carrier. It can be made more hydrophilic to stabilize the water-in-oil emulsion, or more lipophilic to stabilize the oil-in-water emulsion, so as to achieve hydrodeoxygenation under different requirements.

Finally, cool it to room temperature at a rate of 10 °C / min. Then place it in a tube furnace and reduce it at 500 °C under 100 mL / min of hydrogen for 1 h.
[0056] S2. Take five beakers respectively and add 0.5 g, 0.25 g, 0.1 g, 0.067 g, 0.05 g, and 0.04 g of propyltrimethoxysilane into them. Then add them into 20 mL of ethanol and ultrasonicate for 5 min. After that, add 1 g of the solid in S1 into each beaker, ultrasonicate for 100 min, and then let it stand for 12 h.
[0057] S3. Add 30 mL of deionized water into the solution in each beaker obtained in S2, and place them in an oven at 105 °C to dry for 30 min.
