Activated carbons prepared from a broad range of residual agricultural biomass tested for xylene abatement in gas phase

Popis výsledku v původním jazyce

The environmental problems in Peru arise with waste management of the residual agricultural biomass. In our international research cooperation, nine different agricultural wastes from Peru were used as renewable sources to produce activated carbons which were tested in gas phase xylene adsorption. The special properties of agro-waste activated carbons are very large mesopore surface area, narrow pore size distribution within microporous-mesoporous region and slightly acid character with the presence of oxygen-containing surface groups. The textural, structural and surface properties of nine agro-waste activated carbons were correlated with their adsorption capacities in xylene adsorption and compared with a commercial activated carbon made of black coal. Adsorption capacities of agro-waste activated carbons were in the range 371–115 mg xylene/gAC whereas it was 214 mg xylene/gAC for black coal activated carbon. Higher adsorption capacities of ACs can be assigned to the synergism of their textural properties (larger mesopore surface area and higher micropore volume related to total pore volume) and their surface properties (lower content of surface oxygen functional groups related to lower acidic character and higher π-π* transitions in aromatic rings resulting in less defects within graphitic structure).
