Destructive distillation The process of pyrolysis conducted in a distillation apparatus to allow the volatile products to be collected. An example is tar making from pinewood slices (which are rich in terpenes), which are heated in an airless container causing the material to decompose, leaving charcoal and turpentine as byproducts. 3
destructive distillation of solid carbonaceous materials, using direct heating (including the partial combustion of the material to be treated) and/or indirect heating ( external combustion). Destructive distillation specially adapted for particular types of solid raw material or for materials in special form (such as cellulosecontaining
