Adsorption dynamics of phenol in a fixed bed packed with activated carbon and stainless steel fiber-reinforced activated carbon paper
摘要
Abstract
Stainless steel fiber-reinforced activated carbon paper was prepared by a wet papermaking method, followed by a high temperature treatment, using stainless steel fibers as the reinforcement and coniferous wood pulp cellulose as the binder. A fixed bed for phenol adsorption was made by first packing granular activated carbon to a depth of 13 cm followed by 2 cm of the as-made pa-per near the outlet. The adsorption dynamics of phenol in the bed were investigated under different experimental conditions. Results show that the breakthrough curve of phenol in the bed is steeper than that in a bed packed only with activated carbon with the same bed height. The breakthrough time of phenol in the bed decreases and the breakthrough curves become sharper with increasing flow rate and inlet concentration. The length of the unused bed decreases by 14% compared with the bed packed with activated carbon on-ly, indicating that mass transfer in the bed and its utilization ratio are improved by the paper packing.关键词
