Description

Technical Field

[0001] The invention belongs to the technical field of enhancing liquid-solid mass transfer, and in particular relates to a system device and a method for enhancing liquid-solid mass transfer by ultra-gravity. Background Art

[0002] There are many preparation methods for industrial catalysts, but for supported catalysts, the impregnation process is one of the most important steps in catalyst preparation. The impregnation process generally involves immersing the carrier in an impregnation solution. After a period of time, the carrier is filtered, washed, dried, and other operations are performed to obtain a catalyst loaded with active components. Catalyst carriers are generally porous media, such as activated carbon, molecular sieves, MOF, COF, alumina and other materials, which can not only increase the specific surface area of ​​the catalyst, improve heat resistance and mechanical strength, but also act as co-catalysts or promoters; and the impregnation solution generally dissolves the active component in a solvent to form a uniformly dispersed active component solution. There are various types and preparation methods of impregnation solutions. For example, the RLF impregnation solution is an emulsion of a certain concentration obtained by reacting resorcinol with formaldehyde, while the hydrogenation catalyst impregnation solution is a combination of specific metal oxides and organic matter.

[0003] The catalyst impregnation process involves the mass transfer process between the carrier and the impregnation liquid, that is, the liquid-solid mass transfer process. The efficiency and uniformity of the mass transfer will directly determine the density and dispersion of the active components, thereby affecting the catalytic performance of the catalyst. Therefore, for the catalyst impregnation process, using process intensification methods to improve the dispersion uniformity of its active components is an important means to optimize the catalyst preparation process.

[0004] At present, ultra-gravity reactors mainly come in two forms: wire mesh packing and stator-rotor. Since they can shear the fluid into nano-scale droplets or liquid lines through high-speed rotating cutting components, thereby enhancing the mixing and mass transfer efficiency and achieving the purpose of increasing the reaction rate, they are widely used in liquid-liquid reactions or gas-liquid reactions.

[0005] As for liquid-solid reactions, since the reaction solids are basically fine particles or powders, they are difficult to fix in wire mesh packing or stator and rotor structures. Therefore, there is no precedent in the public literature for using ultra-gravity multi-layer packing devices for liquid-solid reactions. Summary of the invention

[0006] The first technical problem to be solved by the present invention is to provide a system device for supergravity enhanced liquid-solid mass transfer. The system device can solve the technical problems of low efficiency and poor dispersion between small particles or powder and liquid mass transfer; the device can fix solid powder 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 system device.

[0019] 2) The impregnation liquid in the circulation tank is sent to the feed port of the supergravity reactor through a circulation pump, and the impregnation liquid is sprayed into the reactor internal components set in step 1) after passing through a liquid distributor;

[0020] 3) The first layer in the middle of the reactor internal component is a packing layer, and the impregnated liquid is cut into nano-scale liquid lines or droplets after passing through the rotating first layer of packing;

[0021] 4) The liquid line or liquid drop formed in step 3) passes through the first layer of filler in the reactor internals and enters the first filling area, and is absorbed by the solid powder filled there;

[0022] 5) The impregnation liquid that is not absorbed continues to be sheared on the second layer of filler, and the liquid lines and droplets formed thereafter are absorbed by the second layer of solid powder until the excess impregnation liquid passes through the outermost filler area and is thrown out of the reactor internal components; and finally flows back to the circulation tank through the discharge port;

[0023] 6) The impregnation liquid flowing back into the circulation tank repeats steps 2) to 5) until the powder reaches a saturated state of adsorbing the impregnation liquid;

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

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

[0037] The present invention optimizes the design of the reactor internal components and divides the internal components into a packing area and a loading area. The packing area is used to fix the wire mesh packing, and the loading area is used to load the solid powder. The wire mesh packing in the packing area can shear the impregnation liquid into nano-microscale liquid lines and droplets, while the solid powder in the adjacent loading area directly contacts the liquid lines and droplets for mass transfer, thereby greatly enhancing the liquid-solid mass transfer efficiency. The traditional impregnation method basically puts the solid powder into the impregnation liquid and achieves the impregnation effect by stirring. This method has low mass transfer efficiency and poor dispersibility. It is difficult for the liquid to enter the powder. Therefore, the pore area cannot be fully utilized, and the prepared catalyst performance is poor. By using the supergravity impregnation method, the liquid-solid mass transfer efficiency can be greatly improved, the permeability of the solid can be improved, and the uniformity of the liquid dispersion in the solid can be increased, thereby improving the catalytic performance.
