About

Slow Pyrolysis technology, according to the International Biochar Initiative (IBI), is  is generally defined as having the following parameters:

• long solids and volatiles residence times [typically greater than 5 s for volatiles; solids residence times can be minutes, hours or days],
  relatively low reactor temperatures [< 400°C],
• atmospheric pressure,
• very low heating rates ranging from 0.01°C/s to up to 2°C/s,
• very low rate of thermal quenching of the products [minutes to hours]
  
  char, viscous tarry liquid and gases are formed in approximately equal mass proportions due to the slow degradation of the biomass and extensive secondary intraparticle and gas/vapour phase reactions.
