Kinetics of Gasoline Vapor Removal in a Poraver Filled Biofilter

Popis výsledku v původním jazyce

The objective of this study was to evaluate the kinetic constants of gasoline degradation in waste gases using a bench-scale biofilter with ID 100 mm and a bed height of 750 mm. The overall, aliphatic and aromatic fractions were analyzed separately. Theconcentrations of pollutants were measured at various points down the bio-reactor to give a concentration profile. The packing material was Poraver (Dennert Poraver GmbH, Germany) with a grain size of 8 - 16 mm. The inlet concentration was kept constantat 250 mg m-3 and the biofilter was loaded by air flow rate.The results showed, as expected, that increasing the residence times improved the removal rates. The aromatic components were removed more rapidly and more completely than the aliphatic compounds. To determine the most appropriate form of the Ottengraf model. The zero order kinetic model was superior. (For aliphatic compounds, use the reaction limited equation and for the aromatic components, diffusion limited was marginally bet
