and local areas with a melted surface
3 Conclusions
In order to obtain PAN granules with a developed porous structure, it is necessary to
use the optimal humidification mode, technological parameters of which are demonstrated in this research. If this mode is not kept, the humidification and heat treatment stages will be ineffective (the uneven humidification mode), or the commodity
qualities of the finished product will be deteriorated (high humidification mode).
The task for further research is to work out the humidification stage with other
humidifiers to define technological parameters for this process implementation.
