Pyrolysis of wood

<< < (2/3) > >>

rolnor:
I made pyrolysis of wood as an experiment as a youth. The tar is mainly used to preserve wood, or? I think before the gas was used in large scale in the same way as propane is today, it is called "lysgas" in swedish, "lightgas".

It appears that during the commercial process they burn the gasses produced during the charcoal process as fuel to produce the charcoal.
