    Kinetics of Gasoline Vapor Removal in a Poraver Filled Biofilter-sborník

  • Original language description

    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

    Kinetika degradace benzínových par v poraverovém biofiltru

  • Czech description

    Práce se zabývala výpočtem kinetických konstant degradace benzínových par podél výšky lože v biofiltru o vnitřním průměru 100 mm a výšce lože 750 mm. Aromatické a alifatické benzínové uhlovodíky byly vyhodnocovány zvlášť. Jako náplňový materiál byl použit Poraver s velikostí částic 8 - 16 mm. Biofiltr byl zatěžován průtokem vzduchu zatím co vstupní koncentrace byla udržována konstantní na hodnotě 250 mg m-3. Byly použity modely degradace navržené Ottengrafem. Pro alifatické uhlovodíky byla nejlépe vyhovující kinetika nultého řádu s reakční limitací a pro aromatické kinetika nultého řádu s difuzní limitací.
