Magnetic stabilization fluid bed device capable of being in the high-pressure environment and method of use thereof

Abstract

The present invention relates to a magnetically stabilized fluidized bed device and the method of applying the same capable of being in high pressure (wherein, the high pressure refers to the pressure higher than 10 atmospheric pressure) environment, wherein the solid adsorbent needed by reverse chromatography consists of powder particles which can be magnetized and has adsorption selectivity, or the mixed powder of magnetisable powder and the powder with adsorption selectivity. After the powder particles are magnetized by the adscititious electric current, the supercritical fluid can be controlled in a specific velocity range, so as to make the powder form a stable fluidized bed in a high pressure pipe string. The present invention further reveals the magnetically stabilized fluidized bed device which is suitable for high pressure fluid and has switch function, so as to realize the separation and purification method of the present invention. The present invention further reveals the powder particle coating and catalytic reaction proceeding technique of the present invention device.

Description

Technical field [0001] The invention relates to a magnetically stable fluidized bed device that can be used in a high-pressure environment and an application method thereof, in particular to a device and a method for obtaining raffinate and extractant by reverse chromatography, thereby achieving separation and purification. Background technique [0002] Since the first extraction plant started operating in 1978, the process technology related to supercritical carbon dioxide has not only triggered a scramble to build extraction plants around the world, the application of carbon dioxide has also rapidly expanded in other fields, such as chromatography, powder material manufacturing and processing. , Polymer synthesis and processing, food and natural product processing and refining, etc.; in terms of application properties, the application of supercritical carbon dioxide in separation and purification has the advantages of low energy consumption and easy downstream processing; among...

AI Technical Summary

Problems solved by technology

[0016] Use three magnetically stable fluidized beds for separation and purification, the first fluidized bed is an adsorption bed, the second is a cleaning bed, and the third is a desorption bed; the concept of the process is similar to the above-mentioned reverse contact continuous chromatography, Only does not reveal how to convey the powder, so it is not suitable for high pressure operation

[0017] 6. Use the powder with magnetizable material as the core and silica as the shell as the material for magnetically stable chromatography; reveal the technology of applying the core-shell structure powder as the magnetically stable fluidized bed, and reveal how to prepare and improve the adsorption selection characteristics, but did not reveal the technology for continuous operation

[0018] 7. The technology of using magnetizable and non-magnetizable mixed powder as a magnetically stable fluidized bed; the cited data does not fully disclose how to use a small amount of magnetizable powder to obtain a magnetically stable fluidized bed technology
