SLOW PYROLYSIS [3 records]

Record 1 1993-07-12

English

Subject field(s)
  • Chemical Engineering
  • Biomass Energy
CONT

Conventional pyrolysis is typically characterized by a slow feedstock heating rate(less than 2 °C/s), low temperatures(less than 500 °C) and relatively long gas and solids residence times(greater than 5 s for the gas; solids residence times can be minutes, hours or days in duration). Tar and char are the primary products due to slow devolatilization of the feedstock, and the secondary coking and polymerization(recombination) reactions which are allowed to occur in the reactor after primary pyrolysis has taken place.

Pyrolysis or thermal decomposition has as an objective the disintegration and depolymerization of lignocellulosics through the action of heat.... slow pyrolysis under reduced pressure : the objective is the separation of the fractions initially depolymerized in order to limit their thermal degradation. We can therefore obtain the primary products of the degradation.

... a term applied to any anaerobic pyrolysis process, fast or slow, which gives a non-condensible synthesis gas or medium energy fuel gas(10-20 MJ/NM3) as the primary product. Tar and char are viewed as undesirable byproducts.
