Pyrolysis - how it works
The diagram
below shows the pyrolysis process developed by BEST Energies Australia
(www.bestenergies.com),
one of the leading companies in biochar commercialisation.

- Biomass
(agricultural waste, papermill waste, chicken litter etc) is
fed into the drier to obtain a moisture content below 5%, before
transfer to the pyrolysis kiln.
- The outputs
of the pyrolysis process will be char and synthesis gas (syngas).
Syngas is composed of combustible gases including hydrogen,
carbon monoxide, methane, and lower molecular weight hydrocarbons,
as well as nitrogen and carbon dioxide. It can be used to fuel
the pyrolysis kiln and drier, used to generate electricity or
exported for use elsewhere.
- The pyrolysis
process can be changed to reflect the required outputs –
slow pyrolysis is good for producing syngas and char, whereas
fast pyrolysis is better for bio-oils.
