Re: Carbon filtering pure distillate
- Hi Peter,
I think that you are a very lucky by not setting your house on fire.
Because the way you dry the carbon in your microwave coud cause a
Through the years I used hundreds kg's of carbon to purify a lot of
When I have to activate carbon (I use 10 kg/ batch) I put it into a
electric oven, set the oven to 180 °C and leave there for 8 hours.
Then I take it out of the oven and let it cool down in a surrounding
where there are no organic vapours are present (I use a stainless
steel box which is filled with nitrogen), after cooling it down to
20°C I use it.
Next time you want to dry carbon just scoop the wet carbon into a
pyrex and put it into a ELECTRIC oven and set it to 180 °C.
Leave the bowl in the oven for a few hours. Take the bowl out the
oven, cover the bowl with aluminum foil and let it cool.
Than use it.
