Abstract

The invention relates to a method and device for separating krypton from xenon by using active carbon. In the method and device, an active carbon absorption column is cooled to reach -80DEG C, a krypton and xenon mixture gas is started to be introduced after the temperature of -80 DEG C is stabilized for 5min for absorbing; and the krypton and xenon mixture gas is separated by using different desorption temperatures of a krypton gas and an xenon gas on the active carbon, thus the enrichment and the separation of the krypton gas and the xenon gas are realized. A separation device based on the method has a reasonable design, and is simple and easy to operate. In addition, the active carbon is used as an absorbing agent, and the regeneration temperature to the active carbon is 200 DEG C, and overhigh regeneration temperature is not used, thus the complexity and the realizing difficulty of the method are reduced.

Description

technical field [0001] The invention belongs to a method and a device for adsorbing and separating krypton and xenon, in particular to a method and a device for adsorbing and separating krypton and xenon with activated carbon. Utilize the difference in dynamic adsorption coefficient and adsorption conditions of krypton and xenon on activated carbon for adsorption, and use the difference in desorption temperature of krypton and xenon on activated carbon for separation; realize the enrichment and separation of krypton and xenon, and provide environmental monitoring Technical Support. Background technique [0002] The concentrations of krypton and xenon in the air are relatively low, and it is difficult to directly separate krypton and xenon from the air. The existing technology is to separate the krypton / xenon from other main components in the air by low-temperature rectification after the air sample is passed through a molecular sieve to remove water and carbon dioxide.
