DEVELOPMENT OF A PLASMA JETTING FLUIDIZED-BED REACTOR

A plasma jetting fluidized bed reactor was developed for coating particles via PCVD. Conversion of methane was carried out to investigate characteristics of this type of reactor. It was found that introduction of reactive gases from the side of a d.c. plasma jet resulted in no deterioration of the stability of plasma and that the reactive gases were effectively activated even in the presence of particles. Particles packed in the reactor promoted reactions to give carbon in the presence of hydrogen in a large excess, strongly suggesting that PCVD on fluidized particles can be realized.
