The paper studies in depth a new technique for mass production of MWCNTs that is based on thermal cracking of polymers in a solid-gas fluidized bed reactor, operated under specific thermal and hydrodynamic conditions. The paper provides information about the phenomenology of interactions between the bed material and the polymer particles injected into the fluidized bed reactor, which in turn affect the mechanism of formation of MWCNTs. Results obtained with different reactor temperature and bed materials are reported in terms of yield and quality of obtained MWCNTs, all characterized by TG-DTA, SEM and TEM microscopy and Raman spectroscopy. It is noteworthy that high-quality MWCNTs were obtained from virgin or recycled polyolefins as well as from recycled polyethylene terephtalate.
