Dear Mr. Wu, Mr.Karve

Thank you very much for the paper and explantion. I can undestand the theory, but I do not know how the apparatus looks like (exp. Oven with N2) and how can I do all the explanation without the apparatus. Could you help me more about it?

Regards,

Darius

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.

Dear Dr. A.D. Karve

Charring material are rubber wood.

Could you tell me the detail process?

Dear Darius,
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. 

Yours
