Chapter 2 Wood carbonisation and the products it yieldsWood Alcohol Journey to Forever

The wood absorbs heat as it is dried giving off its moisture as water vapour steam The temperature remains at or slighly above 100 176 C until the wood is bone dry at 110 to 270 176 C Final traces of water are given off and the wood starts to decompose giving off some carbon monoxide carbon dioxide acetic acid and methanol Heat is absorbedWood alcohol is in any case more expensive than alcohol from sulphite which we will consider Production of this wood alcohol could only become economical if the wood after decomposition could be used for extraction of acetone and methyl alcohol by distillation as intended in the Prodor process Alcohol from Sulphite Liquors

Destructive Distillation an overview ScienceDirect TopicsDestructive distillation

Tar and pitch are viscous dark brown to black substances obtained by the destructive distillation of coal wood petroleum peat and certain other organic materials The heating or partial burning of wood to make charcoal yields tar as a byproduct and is an ancient method for Destructive distillation is the chemical process of the decomposition of unprocessed material by heating it to a high temperature the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents catalysts or solvents such as steam or phenolswikipedia

What is dry distillation Definition of dry distillation Dry distillation hyperleap

Dry distillation is the heating of solid materials to produce gaseous products which may condense into liquids or solids The method may not involve pyrolysis or thermolysis The products are condensed and collected This method usually requires higher temperatures than classical distillationThe method has been used to obtain liquid fuels from coal and woodDry distillation or destructive distillation despite the name is not truly distillation but rather a chemical reaction known as pyrolysis in which solid substances are heated in an inert or reducing atmosphere and any volatile fractions containing high boiling liquids and products of
