The production of alternative fuels recently rediscovered an old process: pyrolysis, which was already used by ancient Egyptian to produce charcoal from wood, and it's still employed nowadays in several industrial processes.
In the field of BTL (biomass-to-fuel) technology, which aims at producing biofuel and syngas from organic waste, pyrolysis is proving to be very promising. Researchers' current objective is to make the process and final product as efficient as possible from an energetic standpoint.
In fact, this is also a rediscovery: pyrolysys was already used to produce fuel during WWII to make up for the scarcity of traditional fuels. After the war however, petrol availability dramatically increased and this field of research was abandoned.
How pyrolysis works
Pyrolysis is a process whereby heat is applied to organic material in absence of oxygen, causing a non-reversible scission of chemical bounds. This way, the typical oxidation of gas compound occurring during combustion is avoided.
The complete process of pyrolyzation is comprised of several phases, and is therefore quite complex. In our workshop we already produce several components for pyrolyzation plants, such as heat exchangers and scrubbers, although we are evaluating the possibility of producing complete plants.
