Description

Technical Field

[0001] This invention belongs to the technical field of enhanced liquid-solid mass transfer, specifically relating to a system device and method for enhancing liquid-solid mass transfer under hypergravity. Background Technology

[0002] There are various methods for preparing industrial catalysts, but for supported catalysts, the impregnation process is one of the most crucial steps. The impregnation process generally involves immersing the support in an impregnation solution. After a period of time, the support is filtered, washed, and dried to obtain the catalyst loaded with the active component. Catalyst supports are typically porous media, such as activated carbon, molecular sieves, MOFs, COFs, and alumina. These materials not only increase the specific surface area of ​​the catalyst and improve its heat resistance and mechanical strength, but also act as co-catalysts or promoters. The impregnation solution is generally a solvent in which the active component is dissolved, forming a uniformly dispersed solution. Impregnation solutions vary in type and preparation method. For example, RLF impregnation solution is an emulsion of a certain concentration obtained by reacting resorcinol with formaldehyde, while hydrogenation catalyst impregnation solutions are combinations of specific metal oxides and organic compounds.

[0003] The catalyst impregnation process involves mass transfer between the support and the impregnation solution, i.e., a liquid-solid mass transfer process. The efficiency and uniformity of this mass transfer directly determine the density and dispersion of the active component, thus affecting the catalyst's catalytic performance. Therefore, for the catalyst impregnation process, improving the dispersion uniformity of the active component using process intensification techniques is an important means of optimizing the catalyst preparation process.

[0004] Currently, there are two main types of centrifugal reactors: wire mesh packing and stator-rotor reactors. Since they can shear fluids into nano- and micro-scale droplets or liquid lines through high-speed rotating cutting components, thereby enhancing mixing and mass transfer efficiency and increasing reaction rate, they are widely used in liquid-liquid or gas-liquid reactions.

[0005] For liquid-solid reactions, since the reaction solids are mostly fine particles or powders, they are difficult to fix in wire mesh packing or stator-rotor structures. Therefore, there are no precedents in the published literature for using a multi-layered packing device with ultragravity for liquid-solid reactions. Summary of the Invention

[0006] The first technical problem this invention aims to solve is to provide a system device for enhancing liquid-solid mass transfer under ultragravity. This system device can solve the technical problems of low efficiency and poor dispersibility in mass transfer between small particles or powders and liquids; the device can fix solid powders and enhance liquid dispersion.

[0007] The second technical problem to be solved by the present invention is to provide a method for enhancing liquid-solid mass transfer using the above-mentioned system device.

[0008] To solve the first technical problem mentioned above, the technical solution adopted by the present invention is as follows: :

[0009] A system device for enhancing liquid-solid mass transfer under hypergravity includes an external circulation hypergravity reactor, a circulation tank, a circulation pump, a motor, and valves;

[0010] The external circulation hypergravity reactor includes a feed inlet, a discharge outlet, an air inlet, an air outlet, a liquid distributor, and internal reactor components.

[0018] 1) Fix the wire mesh packing in the packing area of ​​the reactor internals, fill the solid powder into the packing area of ​​the reactor internals, and seal the reactor internals to prevent the powder from being thrown out;

[0019] 2) The impregnation solution in the circulating tank is pumped into the feed inlet of the supergravity reactor through a circulating pump. After passing through the liquid distributor, the impregnation solution is sprayed into the reactor internals set in step 1).

[0020] 3) The first layer in the middle of the reactor internal components is a packing layer. After the impregnating liquid passes through the rotating first layer of packing, it is cut into nano- and micro-scale liquid lines or droplets.

[0021] 4) The liquid line or droplets formed in step 3) pass through the first layer of packing material in the reactor internal components and enter the first filling zone, where they are absorbed by the solid powder filled there.

[0022] 5) Unabsorbed impregnation liquid continues to be sheared on the second layer of packing, and the resulting liquid lines and droplets are absorbed by the second layer of solid powder until the excess impregnation liquid is thrown out of the reactor internals through the outermost packing zone; finally, it flows back to the circulation tank through the outlet.

[0023] 6) Repeat steps 2) to 5) with the impregnation liquid flowing back into the circulation tank until the powder reaches saturation of the impregnation liquid;

[0024] 7) Remove the internal components of the reactor, pour out the solid powder, and after washing, acid washing, drying and other steps, obtain solid powder loaded with active components.

[0025] Preferably, in step 1), each layer of packing area of ​​the reactor internal components is provided with a column for fixing the wire mesh packing.

[0026] Preferably, in step 1), the wire mesh filler is 1-800 mesh, more preferably 10-500 mesh, and the pore size of the selected wire mesh filler is smaller than the particle size of the solid powder, so as to achieve the purpose of fixing the powder.

[0027] Preferably, in step 1), the upper and lower end faces of the filling area are provided with end caps.

[0028] Preferably, in step 1), the solid powder is one or more of activated carbon, graphene, metal oxide, molecular sieve, MOF material, COF material, diatomaceous earth, kaolin, silica gel, hollow glass microspheres, porous ceramics, carbon nanotubes, graphyne, and silicon carbide.

[0029] Preferably, in step 2), the liquid distributor adopts a circumferentially distributed opening design structure with an aperture of 0.5-5mm, preferably 1-3mm, to improve the initial velocity and dispersion of the impregnation liquid.

[0030] Preferably, in step 3), the rotational speed of the reactor internal components is 300-3000 r / min, more preferably 2000-2850 r / min.

[0031] Preferably, in step 5), the filling zone has 3-20 layers, and the filling zone has 3-20 layers.

[0032] Preferably, in step 6), the cycle time is 0.5-10 hours, more preferably 2-6 hours;

[0033] Preferably, N2, O2, Ar, and CO2 gases are introduced into the interior of the hypergravity reactor through the gas inlet to provide the atmosphere required for the experiment.

[0034] Any range described in this invention includes the endpoint, any value between the endpoints, and any subrange consisting of the endpoint or any value between the endpoints.

[0035] Unless otherwise specified, all raw materials used in this invention can be obtained commercially, and the equipment used in this invention can be conventional equipment in the relevant field or refer to existing technology in the relevant field.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] This invention optimizes the design of the reactor's internal components, dividing them into a packing zone and a loading zone. The packing zone is used to fix the wire mesh packing, while the loading zone is used to load solid powder. The wire mesh packing in the packing zone shears the impregnation liquid into nanoscale liquid lines and droplets, while the solid powder in the adjacent loading zone directly contacts the liquid lines and droplets for mass transfer, thus greatly enhancing the liquid-solid mass transfer efficiency. Traditional impregnation methods typically involve placing solid powder into the impregnation liquid and stirring to achieve the impregnation effect. This method has low mass transfer efficiency and poor dispersibility, making it difficult for the liquid to penetrate the powder's interior, thus failing to fully utilize the pore area and resulting in poor catalyst performance. However, the supergravity impregnation method can significantly improve the liquid-solid mass transfer efficiency, increase the permeability of the solid, and enhance the uniformity of liquid dispersion within the solid, thereby improving catalytic performance.

[0065] According to certain embodiments of the present invention, in step 1), in order to enhance mass transfer and prevent solid powder from being thrown out of the filling area during rotation, the pore size of the selected wire mesh filler needs to be smaller than the particle size of the powder; the wire mesh filler is 1-800 mesh, preferably 10-500 mesh.

[0066] According to certain embodiments of the present invention, in step 1), in order to prevent solid powder from being thrown out of the filling area during rotation, end caps are provided on the upper and lower end faces of the filling area, the purpose of which is to seal the powder in the inner component with the end caps.

[0069] According to certain embodiments of the present invention, in step 3), the rotational speed of the reactor internals is 300-3000 r / min, preferably 2000-2850 r / min.

[0070] According to certain embodiments of the present invention, in step 5), the dimensions of the internal components can be designed according to the reactor dimensions to increase the number of packing zones and filling zones as much as possible, so as to achieve the best liquid-solid mass transfer effect; preferably, the packing zone has 3-20 layers and the filling zone has 3-20 layers.

[0113] Repeat Example 1, except that: the same mass of solid activated carbon was placed in a stirred reactor, and the same volume and concentration of NiCl2 solution were added to the stirred reactor. The stirring speed was set to 1000 rpm, the temperature was controlled at 30°C, and the stirring time was 2 hours. After stirring, the solid activated carbon was removed, and it was acid-washed with hydrochloric acid at 50°C for 2 hours.

[0123] Therefore, it can be concluded that the adsorption of Fe ions in MOF materials can be increased by using supergravity technology, thereby enhancing the liquid-solid mass transfer efficiency.

[0124] Comparative Example 4

[0125] Example 4 was repeated, except that: the same mass of zirconia sheets were placed in a stirred reactor, and the same volume and concentration of hydrochloric acid solution were added to the stirred reactor.
