<DIV>Dear Darius,</DIV>
<DIV> Normally one needs relatively high temperature to make active
charcoal, but the pretreatment with calcium chloride allows us to
make active charcoal even at relatively low temperatures. We make charcoal
from light biomass like agricultural waste and use a TLUD type kiln. You would
have to conduct experiments using your biomass and your process of
charring to see if this pretreatment works in your case or not.
<BR>Yours</DIV>

<DIV>Dear Darius,</DIV>
<DIV>what material are you charring? We make our charcoal from
leaves of sugarcane, which are discarded during the process of sugarcane
harvest. By soaking the leaves in 5% solution of calcium chloride, dying
them and then converting them into char in a TLUD kiln gives us
active charcoal. We have not tested this process in the case of woody
material. Perhaps you can do this experiment. <BR>Yours</DIV>
