| Summary: | Chemical vapour deposition (CVD) reactor is one of the processes commonly used for
carbon nanomaterial (CNM) production. This method is economical and provides high yield of
good quality CNM. However, improvement of the CVD reactor system was necessary due to
its long time requirement to complete each batch of production. A two-stage CVD was
designed, locally fabricated and modified to overcome the limitations. Improvements included
multistage system, which can be used to perform different processes such as floating catalyst
reaction, fixed catalyst process, calcination, reduction and oxidation processes. A cooling
system was added to reduce the production time. The system was further modified to increase
the adsorption capacity of the products. The time requirement for one batch of run was reduced
from 8 hours to 3 hours by improving the system. |
