Abstract
The adsorption capacity for oil products of granulated sorbents prepared by preliminary carbo-nized larch bark activation with water steam in a fluidized bed was studied. The effect of temper-ature and time of carbonized bark activation on the oil sorption capacity of obtained sorbents was investigated. It has been shown that the increase the temperature of activation from 750 °C to 850 °C and the time of treatment from 30 minutes to 90 minutes leads to the increase of the oil static sorption capacity. The maximum oil capacity (6.8 g/g) was achieved for the sorbent with a grain size of 1-2 mm which was prepared by activation of carbonized bark at 850 °C during 30 minutes.
