Dry distillation

A process in which solids (e.g. wood) are heated in the absence of oxygen to release gaseous products that can be, for example, liquefied and further used. Dry distillation may involve pyrolysis, in which complex molecules are broken down into simpler ones. A typical example of dry distillation is the extraction of fuel (pyrolytic gas, wood gas) from wood.
