Re-activating Carbon?!?!?!?

[Guest]

hey guys, I have read on another website, and heard before that you can reactiave carbon by laying it out in the sun for a day? has anyone heard of this, or done this? thanks guys!!!

This is straight from wikipedia, but thought it was useful:

Production

It can generally be produced in two different processes:

1. Physical activation: a process in which the precursor is developed into activated carbons using gases. This is generally done by using one or combining the following processes-(i) Carbonization: a process where material with carbon content is pyrolysed at temperatures in the range 600-900ºC, in absence of air (usually in inert atmosphere with gases like nitrogen, argon) (ii) Activation/Oxidation: a process in which the raw material or carbonised material is exposed to oxidizing atmospheres (carbon dioxide, oxygen or steam) at temperatures above 250 ºC usually in the temperature range 600-1200ºC.
2. Chemical activation: is the other method used for the preparation of activated carbons, which involves impregnation with chemicals such as acids like phosphoric acid or bases like potassium hydroxide, sodium hydroxide or salts like zinc chloride, followed by carbonization process at temperatures in the range 450-900ºC. It is believed that carbonization and activation step proceeds simultaneously in chemical activation. This technique can be problematic in some cases because, for example, zinc trace residues may remain in the endproduct. However, chemical activation is preferred over physical activation owing to the lower temperature and shorter time needed for activating material.

Seeing as though you require very high temperatures to activate the carbon, I'd suspect that you'd need equally high levels to reactivate it (even if that's possible). There's a fellow on ebay who sells 25lb. (5 gal.) quantities of the stuff for a great price. His handle is thirdmillenium, and here's a link:

I ordered from him over a year ago and he had great service. Highly recommended.

Maybe someone else can chime in on the subject,

That's a great link JC.

$30 for a 5 gallon pail is practically free,I paid $150 at the grow shop a couple years ago for the same amount.

dude, i pay out the ass for carbon at the pet store...how much does it cost to get that shit shipped ??? thanks for the link dude...mad props !!!

That's the downfall of shipping activated carbon....it just might double the cost of the item.
He's somewhere in the US, and I live in Canada.
When I ordered it I believe it cost me about $50-$60 total.

I believe the guy got a truckload of the carbon through a Gov't project that was long-ago given the ax. He is in no way affiliated with any Gov't body as far as I'm concerned, and he has "come through" for many people in the mj community.

The quality is top-notch, and so is the price.
Good luck
