- W2315676541 abstract "The present investigation is conerned with developing a process to produce activated carbon from waste polyacrylonitrile by use a fluidized bed for activation.Polyacrylonitrile was first heated in the air at 270°C for 5 hr. Then the product was activated by steam in a batch fluidized bed at 800-900°C for 10-90min. The yield of activated carbon was 20-27 weight percent at 800-900°C activation.The adsorption properties were as followes: for activation temperature 800-900°C, methylene blue adsorbability, 300-400mg/g internal surface area 1, 300-1, 400m2/g.The obtained activated carbon could adsorb butyl mercaptan of 340 weight percent based on the activated carbon.The value is about six times higher than that of those obtained from coconutshell, wood and coal, this excellent quality is probably due to nitrogenous such as nitrile, diazo, and azino compounds found in the activated carbon.Adsorption of mercury, cadmium, chrome, and lead from aqueous solution on this activated carbon was the same as that on the commercial one. Those results showed that the activated carbon obtained in this study is useful for removal of mercaptan, one of air pollutants which can hardly remove by existant adsorbents." @default.
