# Any chemicals combines readily oxygen?

I am designing an industrial process which can remove oxygen from air. This chemical should combine readily with oxygen in the presence of heat.

In particular, I am looking for a chemical with the following properties:

1. Combines readily with oxygen, thus removing the oxygen in air
2. Inexpensive
3. Environmentally friendly

For point #1, heating is available if it is an endothermic reaction.

• Pyrogallol is way too toxic – Sparrowcide Aug 31 '15 at 20:46
• Was afraid you'd raise that :( – Mithoron Aug 31 '15 at 21:06
• At what temperature? Carbon or magnesium would remove oxygen at 1,000 K or higher. Alkaline glucose might be used at room temperature, though it reacts slowly (see faculty.mansfield.edu/bganong/biochemistry/bluebott.htm). More information would be helpful. – DrMoishe Pippik Sep 1 '15 at 0:00
• @DrMoishePippik I am looking at around 800C which is somewhere around 1000K – Sparrowcide Sep 1 '15 at 19:49

If $\ce{CO2}$ is acceptable in the feed gas, along with $\ce{CO}$ and a bit of left-over oxygen, then carbon (coal, charcoal etc.) might do. It's ignition temperature is ~1,000 K.
If you want to absorb only a small amount of O$_2$ to purify an airstream, you should look up gettering. Titanium metal is one of the most popular if you are willing to heat.
