SUMMARY

The discussion centers on the regeneration of L type activated carbon through a thermal process at 400°C, which is commonly performed in kitchen ovens. Users express concerns regarding the potential release of hazardous substances during this process, as not all adsorbed materials may be completely removed. Additionally, the cost-effectiveness of regenerating activated carbon versus purchasing new carbon is questioned. Overall, while regeneration is feasible, it poses risks and may not be economically viable.

PREREQUISITES
  • Understanding of activated carbon properties and applications
  • Knowledge of thermal processes and their effects on materials
  • Familiarity with safety protocols for handling chemicals
  • Basic principles of adsorption and desorption
NEXT STEPS
  • Research the safety implications of regenerating activated carbon at high temperatures
  • Explore alternative methods for activated carbon regeneration
  • Investigate the cost-benefit analysis of using new versus regenerated activated carbon
  • Learn about the environmental impact of activated carbon disposal
USEFUL FOR

This discussion is beneficial for environmental scientists, chemical engineers, and anyone involved in water treatment or air purification processes using activated carbon.

TL;DR
Hot activated carbon and water
Hello i Tried to clean my activated carbon ,washed then put on oven then cool with water again. Is it possble to make anything other than CO2 this way? I read l type is something similar is that hazardous?

A thermal process of 400C is used to create Activated Carbon (activated charcoal).

A common way to "regenerate" the stuff is to bake it in your kitchen oven. That will 'bake out' (vaporize) much of whatever it has adsorbed.

Regeneration has a few potential problems though:
[*] You don't know what or how much is being removed to the surrounding air
[*] Not all of what was adsorbed is likely to be removed
[*] The retail cost of energy to bake it may exceed the carbon replacement cost

Cheers,
Tom
