Charcoal manufacture from coco-nut shell

Abstract

When coco-nut shell is heated in a closed space without the presence of air, decomposition ensues, resulting in the formation of charcoal and in the evolution of large quantities of volatile products which can be recovered only by using an efficient retort and condensing plant. If charcoal alone is required, but no volatile by-products, it is sufficient to carbonize the shells in a stack or pit.
