Fast Pyrolysis of Flax Shive in a Screw‐Type Reactor

A novel screw‐type reactor for the fast pyrolysis of agricultural waste (flax shive) is described. A preliminary study on the influence of process parameters on the yield, composition, and properties of pyrolysis products was carried out. Based on the results obtained, the optimal conditions of fast pyrolysis of flax shive particles in terms of feedstock particle size, solid residence time, and process temperature were identified. Considering the construction, the developed reactor seems to be close to the screw fluidized bed and auger reactor and is characterized by a simple design and operation control. Moreover, the proposed reactor can be used for continuous pyrolysis without any significant modification. A preliminary study of the flax shive fast pyrolysis process in a novel screw‐type reactor is presented. This technique close to the auger reactor exhibits a simple design and effective control over the heating and residence time of the lignocellulosic feedstock. The influence of the main operational parameters on the yield, composition, and properties of pyrolysis products is evaluated.
