<p>PURPOSE: Provided is a process for recovering sulfur hexafluoride (SF6), more specifically, the invention provides a pressure swing adsorption-desorption process for recovering SF6 from a gas stream using zeolites, activated carbons, or silicalites to adsorb the SF6. CONSTITUTION: A process for recovering sulfur hexafluoride comprises the step of contacting a gas stream comprising a minor amount of sulfur hexafluoride with an adsorbent capable of selectively adsorbing sulfur hexafluoride under conditions suitable for the selective adsorption of the sulfur hexafluoride from the gas stream, in which the gas stream comprises the minor amount of sulfur hexafluoride and at least one component selected from the group consisting of air, carbon tetrafluoride, argon, helium, carbon monoxide, carbon dioxide, nitrogen, oxygen, neon, and hydrogen.</p> |
