Recycling of precious metals in catalysts
Thread Content
Currently, the catalysts used for hydrogenation contain iridium, and there is consideration given to recovering this iridium. After the reaction, it remains in the residual liquid; at present, incineration is being considered as a method for recovering iridium, but no effective examples have been found. I’m seeking advice from everyone regarding effective ways to recover precious metals in this situation
Residual liquid. Evaporation – has it been taken into account?
What are the main components of the residue? Is iridium metal iridium powder or some compound of iridium? The information is very incomplete and vague; it is impossible to determine whether methods such as extraction can be used.
The ligand compounds of iridium are in powder form; the residue consists of some high-boiling substances. However, only a very small amount is used as a catalyst – we add just over 100 grams per reaction
If the iridium ligand compound is soluble in water while the high-boiling residue is not, extraction could be considered as a method to try.
Waste catalysts may be considered hazardous waste
How often? Recycling it once a month isn’t worth the effort; recycling it several times a day is something to consider
It depends on your motivation. Contact me.
