Abstract

Manufacturing techniques of activated carbon fiber as well as adsorption system for recovery of dilute methyl bromide have been studied.
As for manufacturing of activated carbon fiber, activated carbon fiber of high adsorbability can be prepared by controlled gasification of carbonized fiber derived from polyvinylidene chloride , phenol resin and coal tar pitch with carbon dioxide or steam.
As for adsorption system, it was found that microwave irradiation for desorption has some advantages over usual hot gas heating.
