Method for forming carbon filters |
摘要 |
In a preferred embodiment, an apparatus and method for forming carbon fibers in a gas phase reaction is disclosed wherein a reactor defines a reaction chamber with a closed end and an outlet and a reactant feed tube which extends generally axially therewithin. Gaseous reactants are injected into the reactor through an opening of the feed tube. The feed tube and chamber are constructed and arranged to define a passageway which is a gas flow path. The reactor includes purge means for intermittently and forcibly moving any fibers clogging the passageway out of the reactor, and means for intermittently oxidizing carbonaceous material in the passageway of the reactor. In use, a period of fiber formation is followed by a forced purge. Periodically, an oxidation purge is used to essentially cleanse the reactor.
