Biomass is a fuel with a highly volatile content and due to that, pyrolysis
as a part of the combustion process, has a dominant role in the overall
process development, as well as on final products and the process efficiency.
It is of key importance to investigate the influence of the process
parameters; as temperature, furnace/reactor environment, fuel properties,
type, particle size, geometry, and the structure of the pyrolysis process has
an influence regards the design of the combustion/pyrolysis equipment and the
final products of the processes. This paper gives some results of the
investigation’s related to this problem, mainly focussing on wooden biomass
as the most important biomass type, as well as a comparison with relevant
documented literature. Besides that, pyrolysis based technologies are one of
the key directions in synthetic fuels production based on biomass. Biomass
pyrolysis process parameters are crucial in reactor design as well as the
quantity and quality of the final products. This paper provides discussion
dedicated to this aspect with a focus on slow pyrolysis, targeting charcoal
as the key product, and fast pyrolysis, targeting synthetic gas as the key
product.
