Me and my friends are doing a project involving carbon monoxide and carbon dioxide as products to be filtered, we are using zeolites and would like to know the zeolite type typically used to filter $\ce{CO}$ and $\ce{CO2}.$

    $\begingroup$ Welcome to Stack Exchange! It's better to take a moment to describe what you know based on information you have read or searched already. Stack Exchange shouldn't be your "first stop". If you have identified at least some zeolite materials that can do this as proof of principle, you should mention it in your question. Thanks! $\endgroup$ – uhoh May 17 '19 at 3:13

    $\begingroup$ NASA uses lithium hydroxide and silver oxide to remove CO2, but I'm not sure about the effectiveness for CO. Why zeolites? space.stackexchange.com/a/32177/12102 and also this PDF ttu-ir.tdl.org/bitstream/handle/2346/74151/… $\endgroup$ – uhoh May 17 '19 at 3:48
  • $\begingroup$ My apologies, uhoh. I have researched the question however I was unable to find information on zeolites that would typically be used to filter CO and CO2. However thank you for the information on Lithium Hydroxide and Silver Oxides! $\endgroup$ – Wüolf Schülman May 17 '19 at 7:22

    $\begingroup$ @uhoh The idea of using zeolithes is to have an easily reversible (by simply changing the pressure) adsorption. It's a well introduced method for gas separation. LiOH absorbs CO2, and you need an energy-intensive chemistry to get it back out again. $\endgroup$ – Karl May 17 '19 at 7:53
  • $\begingroup$ @Karl I see what you mean! $\endgroup$ – uhoh May 17 '19 at 13:15
