Editing Destructive distillation (section)

==Process==
The process of [[pyrolysis]] can be conducted in a distillation apparatus ([[retort]]) to form the volatile products for collection. The mass of the product will represent only a part of the mass of the feedstock, because much of the material remains as char, ash, and non-volatile tars. In contrast, [[combustion]] consumes most of the organic matter, and the net weight of the products amount to roughly the same mass as the fuel and oxidant consumed.

Destructive distillation and related processes are in effect the modern industrial descendants of traditional [[charcoal]] burning crafts. As such they are of industrial significance in many regions, such as Scandinavia. The modern processes are sophisticated and require careful engineering to produce the most valuable possible products from the available feedstocks.<ref>Bates, John S.; Distillation of hardwoods in Canada; Pub: Ottawa, F.
