I’ve known it could be made in a process but wasn’t sure of the steps, so I buy it. Now no matter where I am with your clear steps, I can make activated charcoal myself. Thanks for this excellent video.
Using a burn barrel with a smaller metal barrel with lid to fit inside is also used to make charcoal put hard wood inside smaller barrel close then use scrap wood or waste wood to burn around the small barrel inside the larger one and bam you have alot of good charcoal
Hey I believe people mix lemon juice with charcoal that’s already activated in order to make face scrubs but I don’t believe it aids the activation process, let me know if that’s wrong! And then it would be tough to get an oven to 550 C( 1000 F).
Well explained. Although you don't include a demonstration of how effective activated charcoal is, made by this method, I found your clip comparing this product with a commercially available one. Very good. Can you explain why aerobic heating to 500-600°C for that specific amount of time is so effective? Are low volatile materials in the microscopic cavity structure being 'boiled' off or combusted?
My best guess is that heating removes the tar, soot ect that would then allow the pores to open as it's all burnt away but I always thought steam introduction was the best way as it expands those pores by a few time's, think of it like expanded clay pellets or even popcorn.
Great question! It’s harder to regulate the temperature in the cast iron skillet. If you get too hot, it’s hard to bring the temp down with just the burners.
@@LAzereye13 so what are you using? most other metals used for pans are in the range of melting at those temps and in the video you call it a "plate", what, like a dinner plate? i dunno
Hey there I burned out a couple bullet grinders trying to make this and it didn’t seem quite as fine and therefore my samples at the end weren’t as clear. A vitamix may do better though I’d love to hear if you try it sometime!
This is not activated charcoal its just charcoal made into dust and then burned while being contaminated with the air particles/dust ect... To activate you must use acid like lemon juice or hot steam in a enclosed area free from pollutants . With acid you have to let it soak for 24 hours or so then you rinse it with distilled water and put in a oven or air fryer to slowly dry. . This can still be used we a filter but wont be as effective
@@mobmob5944 don’t you realize that if it’s effective at filtering at all, it’s activated? It might be “less activated” than commercial grade charcoal but it’s a good solution for people that don’t own expensive equipment/chemicals and need something quickly. Try running methyl orange solution through a filter of inactivated charcoal or straight dirt…what comes out won’t be clear, it’ll be orange. We used the activated charcoal in this experiment in homemade filters and had pretty good results with clear water coming through.
@@PJ-vb3fl no its just called charcoal, even if you crush it to dust and burn it 100 times back to back . And yes inactivated charcoal will filter water pretty good still because it will have pores. Not as good as charcoal activated by super hot steam which the steam drills out more pores in the charcoal increasing the surface area by over 1000x
