Dear Darius, 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.
