Abstract

Some features of water-steam activation in fluidized bed reactor of larch bark and solid residues of bark extraction processing were studied. It was established that the reactivity of charcoal obtained from the extracted bark is significantly higher than the reactivity of charcoal obtained from raw bark and the duration of activation of charcoal from extracted bark is less by 3 times as compared to charcoal from original bark. It was shown that the yield of activated carbon and its sorption characteristics depend on the size of the fraction of the feedstock and they practically do not depend on the number of stages of extraction processing. All samples of activated carbon from larch bark have a high adsorption capacity on iodine (99 %) which is higher than that of the industrial active charcoal BAU
