Description

Technical Field

[0001] The utility model relates to the technical field of supported catalyst preparation, in particular to a catalyst activation device. Background Art

[0002] At present, in the polyolefin industry, catalysts are still the core technology. Among them, supported catalysts have been widely used due to their own advantages and good device applicability. The preparation of supported catalysts is inseparable from the carrier material. Among the many carrier materials, porous media can provide good chemical reaction sites for active components and are widely used. In order to adapt to the process needs of existing devices, when preparing and producing catalysts, a porous medium is generally preferred as a catalyst carrier, and then consider how to load the active components onto the porous medium, and obtain a catalyst with good performance through loading process control. The catalyst obtained in this way not only has good polymerization characteristics, but also can well maintain the particle morphology of the porous medium, laying the foundation for meeting the application requirements of the production device.

[0003] Generally speaking, there are many poisons on porous media. If they are not treated, the active centers will be poisoned, affecting the performance of the final catalyst. The common practice is to treat the porous media before use, including drying and high-temperature treatment, to achieve the effect of removing poisons in the carrier, such as free water, hydroxyl groups, dihydroxyl groups and free hydroxyl groups on the surface. In the selection of porous media, it is generally required to have a high specific surface area, a more suitable pore volume and pore size distribution, good fluidity, a suitable bulk density and mechanical strength. The usual process is as follows: Place the porous medium in an activation furnace, heat it according to the set requirements, and the fluidizing gas enters from the bottom of the activation furnace to put the porous medium particles in a fluidized state. Heat it to a specified temperature (such as 600°C), and treat it for a certain time according to the process requirements, and then cool it down to complete the carrier treatment process.

[0004] When treating different types of catalyst carriers, the activation furnace needs to be cleaned. This is because different types of catalysts can interfere with each other, and some catalysts can even be toxic to each other. This requires a thorough cleaning of the activation furnace before treatment. In the prior art, activation furnaces are typically installed in a fixed position and cannot be moved. To clean the activation furnace, it is generally necessary to remove the activation furnace, use a lifting device to lift the activation furnace to another location, and then lay it down for cleaning. This places high demands on the space size, especially the height, of the room where the activation furnace is located. The activation furnace is not easy to disassemble and clean, making the operation difficult. Utility Model Content
