Staged pyrolysis

Staged Pyrolysis: Example of possible implementation of this technology.

Pyrolysis is the thermal decomposition of organic matter such as ligno-cellulosic biomass under the influence of the heat under an inert atmosphere. It produces non condensable gas, bio-oil and biochar. The pyrolysis oil includes more than 300 valuable oxygenated compounds such as furans, ketones, phenols and esters (see: Biochemicals from Pyrolysis). Certain phenolic compounds are known for their insecticidal and fungicidal effects. Different constituents of bio-oil can be difficult to separate. However, the composition of the off-gas is strongly influenced by temperature (see also: Wood Preservation by Carbonization). Therefore a staged pyrolysis in temperature can be applied.
