There are many pyrolysis technologies in the market and they differ deeply accordingly to their operational conditions.
The most important differences between pyrolysis technologies regard the reactor type (fluidized bed, fixed bed, rotating drum), the residence time (flash pyrolysis 1s, fast pyrolysis 2s, slow pyrolysis 40min-1h) and the temperature (low 400°C, medium 600-800°C, high >800°C).
The differences in operation conditions result in the generation of different products. For example, the carbonization, is a type of pyrolysis that generates mainly charcoal. Under other conditions it can generates mainly a liquid fuel called biooil and under other conditions gas is the main product, called syngas.
