Pyrolysis liquid from wood (pine) and from straw
Fast pyrolysis is a process that consists in heating organic materials in absence of air in order to produce organic vapours that can be condensed to obtain a liquid: the pyrolysis oil. Up to 70 wt.% of the feedstock is converted into this dark-coloured liquid, which contains almost no minerals and sulphur components.
The production of pyrolysis oil offers several advantages:
- Pyrolysis oil is easy to store and to transport. Pyrolysis makes it possible to decouple biomass supply and biofuel demand.
- Application of liquid biofuels such as pyrolysis oil is easier than that of solid biofuels.
- Pyrolysis oil is second-generation biomass technology and does not interfere with the food chain.
- Pyrolysis oil is a greenhouse gas neutral biofuel.
Pyrolysis oil characterized (wood derived):
|Higher heating value||17-20 GJ/m3|
|Water content||15-30 wt.%|
|Ash||< 0.1 wt.%|
