[[Pyrolysis]] is the thermal decomposition of organic matter under an inert atmosphere. Ligno-cellulosic biomass is a common feedstock. The process produces non-condensable gas, [[Pyrolysis Oil|bio-oil]] and [[biochar]]. The pyrolysis oil includes more than 300 valuable oxygenated compounds, such as furans, ketones, phenols and esters (see also: [[Biochemicals from Pyrolysis]]). Certain phenolic compounds are known for their insecticidal and fungicidal effects.
=Example of Protocol=
Different constituents of [[Pyrolysis Oil|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, when temperature is applied in different stages, different fractional components can be captured (hence: "staged pyrolysis"). In other words, the value fraction from each step is improved and tar formation is minimized.
