| Popis: | The main challenges for the development of an industrial process for carbon nanotubes (CNTs) synthesis are the formation of agglomerates and the control of their size distribution. The project objective was to investigate the feasibility of CNT grinding with two arrangements. Experiments showed that a commercial jet mill can meet product quality requirements. However, in-situ grinding of CNTs, within the fluidized bed reactor, would improve both the productivity and quality of CNTs. A new, two-parameter grinding model shows that the primary grinding mechanism is fragmentation for the jet mill and erosion in the fluidized bed column. |
